This document describes changes between tagged Emscripten SDK versions.
Note that version numbers do not necessarily reflect the amount of changes
between versions. A version number reflects a release that is known to pass all
tests, and versions may be tagged more or less frequently at different times.
Note that there is no ABI compatibility guarantee between versions - the ABI
may change, so that we can keep improving and optimizing it. The compiler will
automatically invalidate system caches when the version number updates, so that
libc etc. are rebuilt for you. You should also rebuild object files and
libraries in your project when you upgrade emscripten.
Not all changes are documented here. In particular, new features, user-oriented
fixes, options, command-line parameters, breaking ABI changes, deprecations,
significant internal modifications and optimizations etc. generally deserve a
mention. To examine the full set of changes between versions, you can use git
to browse the changes between the tags.
See docs/process.md for more on how version tagging works.
3.1.6
- Remove support for deprecated EMMAKEN_COMPILER, EMMAKEN_CFLAGS, and
EMMAKEN_NO_SDK environment variables. These are all legacy and redundant
in the face of other settings/flags:
- EMMAKEN_COMPILER -> LLVM_ROOT in the config settings
- EMMAKEN_CFLAGS -> EMCC_CFLAGS
- EMMAKEN_NO_SDK -> standard -nostdlib and -nostdinc flags
- emscripten will no longer automatically create a config file if it can't
find one in the configured location. Instead, it will error out and point the
user to the --generate-config option, in case that is what they want.
(#13962)
3.1.5 - 02/17/2022
- Emscripten no longer uses the allocate() runtime function. For backwards
compatabiliy with external JS code we still include this function by default
but it will no longer be included in -sSTRICT mode. Usages of this function
are generally best replaced with _malloc, stackAlloc or allocateUTF8.
3.1.4 - 02/14/2022
- Due to an llvm change (https://reviews.llvm.org/D118573) some clang flags
that did not previously have any effect are now honored (e.g.
-fnew-alignment and -fshort-wchar).
- llvm dependency updated to 15.0.0 to match upstream. (#16178)
- The __EMSCRIPTEN_major__, __EMSCRIPTEN_minor__ and __EMSCRIPTEN_tiny__
macros are now available via the emscripten/version.h header file. For the
time being, unless you enable -sSTRICT, these are still also defined
directly on the command line. If you use these macros please make sure you
include emscripten/version.h (or emscripten.h which indirectly includes
it). (#16147)
3.1.3 - 01/31/2022
- The file packager now supports embedding files directly into wasm memory and
emcc now uses this mode when the --embed-file option is used. If you
use file_packager directly it is recommended that you switch to the new mode
by adding --obj-output to the command line. (#16050)
- The --bind flag used to enable embind has been deprecated in favor of
-lembind. The semantics have not changed and the old flag continues to
work. (#16087)
- New setjmp/longjmp support using Wasm EH instructions is added, which is
faster and reduces code size. You need a browser that supports Wasm EH spec to
use it. The new SjLj support is enabled by -sSUPPORT_LONGJMP=wasm. This can
be used with Wasm exception support (-fwasm-exceptions), but not with
Emscripten exception support (-fexceptions or
-sDISABLE_EXCEPTION_CATCHING=0). When using Wasm EH with Wasm SjLj, there is
one restriction that you cannot directly call setjmp within a catch
clause. (Calling another function that calls setjmp is fine.)
(#14976 and #16072)
3.1.2 - 01/20/2022
- A new setting, POLYFILL, was added which is on by default but can be disabled
(via -sNO_POLYFILL) to prevent emscripten from outputing needed polyfills.
For default browser targets, no polyfills are needed so this option only has
meaning when targeting older browsers.
- EVAL_CTORS has been rewritten and improved. The main differences from before
are that it is much more capable (it can now eval parts of functions and not
just all or nothing, and it can eval more wasm constructs like globals). It is
no longer run by default, so to use it you should build with -s EVAL_CTORS.
See settings.js for more details. (#16011)
- wasmX test suites that are defined in test_core.py have been renamed to
coreX to better reflect where they are defined. The old suite names such
as wasm2 will continue to work for now as aliases.
3.1.1 - 01/08/2022
- Happy new year!
- Updated SDL 2 port to upstream version 2.0.18 (from a patched 2.0.10). This
includes all downstream patches and many upstream changes.
- libc++ library updated to llvm-13. (#15901)
- libc++-abi library updated to llvm-13. (#15904)
- compiler-rt library updated to llvm-13. (#15906)
- Added new internal/debugging related environment variable
EM_FORCE_RESPONSE_FILES that can be set to 0 to force disable the use of
response files, and to 1 to force enable response files. If not set,
response files will be used if command lines are long (> 8192 chars). (#15973)
3.1.0 - 12/22/2021
- Emscripten in starting to use ES6 features in its core libraries (at last!).
For most users targeting the default set of browsers this is a code size win.
For projects targeting older browsers (e.g. -sMIN_CHROME_VERSION=10),
emscripten will now run closure compiler in WHITESPACE_ONLY mode in order to
traspile any ES6 down to ES5. When this automatic transpilation is performed
we generate a warning which can be disabled (using -Wno-transpile) or by
explicitly opting in-to or out-of closure using --closure=1 or
--closure=0. (#15763).
3.0.1 - 12/17/2021
- Deprecate EMMAKEN_CFLAGS is favor of EMCC_CFLAGS.
- Fixed an issue where user provided --js-library directives would not be
processed as the last item after all system provided JS libraries have been
added to the build. This fix enables overriding WebGL 2 symbols from user JS
libraries.
3.0.0 - 11/22/2021
- A set of internally-unused functions were removed from parseTools.js. While
emscripten no longer needs any of these functions, there is slim chance that
some external JS library is depending on them. Please file issues if any such
library code is found. The removed/unused functions are:
removePointing, pointingLevels, removeAllPointing, isVoidType,
isStructPointerType, isArrayType, isStructType, isVectorType,
isStructuralType getStructuralTypeParts, getStructuralTypePartBits,
isFunctionDef, isPossiblyFunctionType, isFunctionType, getReturnType,
splitTokenList, _IntToHex, IEEEUnHex, Compiletime.isPointerType,
Compiletime.isStructType, Compiletime.INT_TYPES, isType.
- The example shell.html and shell_minimal.html templaces no longer override
printErr on the module object. This means error message from emscripten and
stderr from the application will go to the default location of console.warn
rather than console.error. This only effects application that use the
example shell html files.
- The version of musl libc used by emscripten was upgraded from v1.1.15 to
v1.2.2. There could be some minor size regressions (or gains) due to changes
in upstream musl code but we don't expect anything major. Since this is a
fairly substantial change (at least internally) we are bumping the major
version of Emscripten to 3. (#13006)
- Added support for specifying the text encoding to be used in response filenames
by passing the encoding as a file suffix (e.g. "a.rsp.utf-8" or "a.rsp.cp1252").
If not specified, the encoding is autodetected as either UTF-8 or Python
default "locale.getpreferredencoding()". (#15406, #15292, #15426)
2.0.34 - 11/04/2021
- Symbols marked as visibility hidden are no longer exported from C/C++
code when building with SIDE_MODULE, MAIN_MODULE or LINKABLE. If you
need to export a hidden symbol you can still do so by adding it to
EXPORTED_FUNCTIONS.
2.0.33 - 11/01/2021
- Bug fixes
2.0.32 - 10/19/2021
- Internal-only library functions can now be marked as __internal: true in JS
system libraries. Such symbols should not be used by external libraries and
are subject to change. As of now we generate warning when external libraries
depend on the these symbols.
- Stub functions from library_syscall.js and library.js were replaced with
native code stubs (See system/lib/libc/emscripten_syscall_stubs.c). This
should be better for wasm module portability as well as code size. As part
of this change the return value of popen was fixed to return NULL rather
than -1 and the getpwnam family of functions were changed to return an
error rather than throw a JavaScript exception (this behaviour matches what
the other stub functions do). As before, the ALLOW_UNIMPLEMENTED_SYSCALLS
setting controls whether of not these stubs get included at link time, and
STRICT disables this setting.
- Emscripten will now warn when linker-only flags are specified in
compile-only (-c) mode. Just like with clang itself, this warning can be
disabled using the flag: -Wno-unused-command-line-argument.
- Internal symbol names for musl syscalls changed from number-based (e.g.
__syscall22) to name-based (e.g. __syscall_open). This should not be
a visible change except for folks trying to intercept/implement syscalls
in native code (#15202).
- Fixed launcher batch script issues on Windows, and added two env. vars
EM_WORKAROUND_PYTHON_BUG_34780 and EM_WORKAROUND_WIN7_BAD_ERRORLEVEL_BUG that
can be enabled to work around a Windows Python issue
https://bugs.python.org/issue34780 , and a Windows 7 exit code issue (#15146)
- Support a new CMake propert EMSCRIPTEN_SYSTEM_PROCESSOR which can be used
to override the default value of CMAKE_SYSTEM_PROCESSOR set by the
toolchain file.
- Remove support for the EMIT_EMSCRIPTEN_METADATA setting. This setting has
been deprecated for some time now and we don't know of any remaining reasons to
keep it around.
- Add JavaScript API Emval.{toHandle, toValue} as well as a C++ method
val::as_handle() to allow passing values between the val class and
EM_JS/ EM_ASM JavaScript snippets. (#15279)
- Added SAFE_HEAP=2 option which tests safe heap behavior for wasm-only builds
(allowing unaligned memory accesses, which would not work in Wasm2JS but in
wasm would be correct but potentially slow).
2.0.31 - 10/01/2021
- Bug fixes
2.0.30 - 09/14/2021
- Bug fixes
2.0.29 - 08/26/2021
- Bug fixes
2.0.28 - 08/23/2021
- Added some support for signal handling libc functions (raise, kill,
sigaction, sigpending, etc). We still don't have a way to deliver signals from
the outside but these at least now work for sending signals to the current
thread (JS context) (#14883).
- Remove the workaround used in emcmake and emmake that removed directories
with sh.exe from PATH on Windows when MinGW Makefiles generator was used.
This was needed with CMake versions older than 3.17.0. If you get an error
"sh.exe was found in your PATH" on Windows, you can either update to CMake
3.17.0 or newer, or remove the offending directory from your PATH. See
https://github.com/Kitware/CMake/commit/82ddcf0db1d220564145122c3cce25d25ee0e254
for more information. (#14930)
2.0.27 - 08/12/2021
- Added EM_ASYNC_JS macro - similar to EM_JS, but allows using await
inside the JS block and automatically integrates with Asyncify without
the need for listing the declared function in ASYNCIFY_IMPORTS (#9709).
- Errors that occur on pthreads (e.g. uncaught exception) will now get re-thrown
on the main thread rather than simply being logged (#13666).
2.0.26 - 07/26/2021
- When building ports with the embuilder tool some of the names of the
libraries have changed (they now match the filenames in the tools/ports/
directory). For example sdl-image is now sdl_image (#14737).
- Undefined data symbols (in static executables) are no longer silently ignored
at link time. The previous behaviour (which was to silently give all
undefined data symbols address zero, which could lead to bugs)
can be enabled by passing either -Wl,--allow-undefined or
-Wl,--unresolved-symbols=ignore-all.
- The alignment of long double, which is a 128-bit floating-point value
implemented in software, is reduced from 16 to 8. The lower alignment allows
max_align_t to properly match the alignment we use for malloc, which is 8
(raising malloc's alignment to achieve correctness the other way would come
with a performance regression). (#10072)
- The alignMemory function is now a library function and therefore not
included by default. Debug builds will automatically abort if you try
to use this function without including it. The normal library __deps
mechanism can be used to include it, or can be added to
DEFAULT_LIBRARY_FUNCS_TO_INCLUDE.
- dlopen can now load libraries at runtime from the web without preloading
or embedding. This features relies on ASYNCIFY to suspend execution until
the library is loaded and then continue on as if dlopen was blocking. For
users who don't want to use ASYNCIFY (which has a size and runtime cost)
there is a async (callback-based) version of the dlopen API available as
emscripten_dlopen() declared in emscropten/emscripten.h. See
docs/api_reference/emscripten.h.rst (or the online version) for more
details.
- Constructors, functions and methods bound with Embind can now be awaited.
When Asyncify is used somewhere in the callstack, previously Embind would
return 0 / null / false / instance with a NULL pointer, making it
impossible to wait for the function to actually finish and retrieve its
result. Now in those cases it will return a Promise instead that will
resolve with the function's return value upon completion. (#11890)
2.0.25 - 06/30/2021
- Support for the 'shell' environment is now disabled by default. Running under
d8, js, or jsc is not something that most emscripten users ever want to
do, so including the support code is, more often than not, unnecessary. Users
who want shell support can enable it by including 'shell' in -s ENVIRONMENT
(#14535).
- A new setting called ALLOW_UNIMPLEMENTED_SYSCALLS was added. This setting
is enabled by default but, if disabled, will generate link-time errors if
a program references an unimplemented syscall. This setting is disabled
by default in STRICT mode.
- By default (unless EXIT_RUNTIME=1 is specified) emscripten programs running
under node will no longer call process.exit() on exit(). Instead they
will simply unwind the stack and return to the event loop, much like they do
on the web. In many cases the node process will then exit naturally if there
is nothing keeping the event loop going.
Note for users of node + pthreads: Because of the way that threads are
implemented under node multi-threaded programs now require EXIT_RUNTIME=1
(or call emscripten_force_exit) in order to actually bring down the process.
- Drop support for node versions older than v5.10.0. We now assume the
existence of Buffer.from which was added in v5.10.0. If it turns out
there is still a need to support these older node versions we can
add a polyfil under LEGACY_VM_SUPPORT (#14447).
2.0.24 - 06/10/2021
- Support --preload-file in Node.js. (#11785)
- System libraries are now passed to the linker internally via -lfoo rather
than using their full path. This is in line with how gcc and clang pass system
libraries to the linker. This should not effect any builds unless a project a
happens to have, for example, a file called libc.a in one of its library
paths. This would have the effect of overriding the system library (as it
would with gcc or clang) (#14342).
- CMake projects (those that either use emcmake or use Emscripten.cmake
directly) are new configured to install (by default) directly into the
emscripten sysroot. This means that running cmake --install (or running the
install target, via make install for example) will install resources into
the sysroot such that they can later be found and used by find_path,
find_file, find_package, etc. Previously the default was to attempt to
install into the host system (e.g /usr/local) which is almost always not
desirable. Folks that were previously using CMAKE_INSTALL_PREFIX to build
their own secondary sysroot may be able to simplify their build system by
removing this completely and relying on the new default.
- Reinstated the warning on linker-only -s settings passed when not linking
(i.e. when compiling with -c). As before this can disabled with
-Wno-unused-command-line-argument (#14182).
- Standalone wasm mode no longer does extra binaryen work during link. It used
to remove unneeded imports, in hopes of avoiding nonstandard imports that
could prevent running in WASI VMs, but that has not been needed any more. A
minor side effect you might see from this is a larger wasm size in standalone
mode when not optimizing (but optimized builds are unaffected). (#14338)
- You can now explicitly request that an environment variable remain unset by
setting its value in ENV to undefined. This is useful for variables, such
as LANG, for which Emscripten normally provides a default value.
2.0.23 - 05/26/2021
- libcxxabi updated to llvm-12. (#14288)
- libcxx updated to llvm-12. (#14249)
- compiler-rt updated to llvm-12. (#14280)
2.0.22 - 05/25/2021
- Fix a crash bug that was present in 2.0.21 with the use of -g. See
https://reviews.llvm.org/D102999.
- wasm-ld will now perform string tail merging in debug string sections as well
as regular data sections. This behaviour can be be disabled with -Wl,-O0.
This should significantly reduce the size of dwarf debug information in the
wasm binary.
- The experimental SPLIT_MODULE setting now expects the secondary module to be
named <module>.deferred.wasm instead of <module>.wasm.deferred.
- sendfile.h header removed from musl. (#14248)
2.0.21: 05/18/2021
- Options such as EXPORTED_FUNCTIONS that can take a response file containing
list of symbols can now use a simple one-symbol-per-line format. This new
format is much simpler and doesn't require commas between symbols, opening
or closing braces, or any kind of escaping for special characters.
- The WebAssembly linker (wasm-ld) now performes string tail merging on any
static string data in your program. This has long been part of the native
ELF linker and should not be observable in well-behaved programs. This
behavior can be disabled by passing -Wl,-O0.
- The functions fork, vfork, posix_spawn and system now fail with
the errno value ENOSYS (52) rather than EAGAIN (6). This is more
correct, since they will never work and attempting to retry won't help.
- EXPORT_ES6 will now emit static URLs for main WebAssembly file as well
as for helper Worker used by -pthread that can be statically detected
by modern bundlers at build time. In particular, you no longer have to set
Module.locateFile hook and Module.mainScriptUrlOrBlob settings -
both bundlers and browsers should pick up the required files automatically.
Note: this doesn't yet cover other use-cases that emit external files,
such as dynamic linking, --proxy-to-worker, external memory etc. (#14135)
- EXPORT_ES6 can now be used in combination with -o [filename].html. (#14165)
- EXPORT_ES6 no longer requires setting custom EXPORT_NAME too. (#14139)
- New diagnostics allow Emscripten to issue warnings when using Intel SIMD
intrinsics (from xmmintrin.h) which have slow emulations rather than fast
WebAssembly equivalents. To enable them, define WASM_SIMD_COMPAT_SLOW
in the preprocessor (#14152)
2.0.20: 05/04/2021
- This ChangeLog and the emscripten-version.txt file that is checked into
the repository now reflect the next, upcoming, release once a release is
made. Previously they would continue to reflect the old release until after
we decide to cut the release. Switching to this method allow for a slightly
simpler release process that also allows us to tag a version that contains
the correct version information.
- The version string reported by -v/--version now includes a -git suffix
(e.g. 2.0.19-git) when running from git checkout (to help distinguish
unreleased git versions from official releases) (#14092).
- Temporarily back out new -Wunused-command-line-argument warnings introduced
in 2.0.19.
2.0.19: 05/04/2021
- Emscripten will now warn when linker-only -s settings are specified in
compile-only (-c) mode. Just like with clang itself, this warning can be
disabled using the flag: -Wno-unused-command-line-argument.
- When building with -s MAIN_MODULE emscripten will now error on undefined
symbol by default. This matches the behvious of clang/gcc/msvc. This
requires that your side modules be present on the command line. If you do not
specify your side modules on the command line (either direcly or via
RUNTIME_LINKED_LIBS) you may need to add -s WARN_ON_UNDEFINED_SYMBOLS=0 to
avoid errors about symbol that are missing at link time (but present in your
side modules provided at runtime). We hope that this case is not common and
most users are building with side modules listed on the command line (#14060).
- The RUNTIME_LINKED_LIBS setting is now deprecated. It's better to simply
list dynamic library dependencies directly on the command line.
2.0.18: 04/23/2021
- The makeBigInt function was removed from the emscripten runtime since it
had no internal users.
- Restored support for --cache command line flag to configure location of the
Emscripten cache root directory.
- EXTRA_EXPORTED_RUNTIME_METHODS is deprecated in favor of just using
EXPORTED_RUNTIME_METHODS.
- When building with MAIN_MODULE=2 the linker will now automatically include
any symbols required by side modules found on the command line. This means
that for many users of MAIN_MODULE=2 it should no longer be necessary to
list explicit EXPORTED_FUNCTIONS. Also, users of MAIN_MODULE=1 with
dynamic linking (not dlopen) who list all side modules on the command line,
should be able to switch to MAIN_MODULE=2 and get a reduction in code size.
- When building with MAIN_MODULE it is now possbile to warn or error on
undefined symbols assuming all the side modules are passed at link time. This
means that for many projects it should now be possbile to enable
ERROR_ON_UNDEFINED_SYMBOLS along with MAIN_MODULE.
2.0.17: 04/10/2021
- Use of closure compiler (--closure) is now supported when using dynamic
linking (building with -s MAIN_MODULE) (#13880)
- Specifying EM_CONFIG inline (python code in the environment variable itself)
is no longer supported (#13855). This has been long deprecated but finally
completely removed.
- Deprecate -g4, which is a little confusing as it does not do more than -g3
but instead emits source maps instead of DWARF. -g4 will now warn. A new
flag -gsource-map enables source maps without warning.
- In order to behave more like clang and gcc, emscripten no longer
supports some nonstandard methods of library lookup (that worked
unintentionally and were untested and not documented):
1. Linking with -llibc rather than -lc will no longer work.
2. Linking a library called foo.a via -lfoo will no longer work.
(libraries found via -l have to start with lib)
- Use LLVM's new pass manager by default, as LLVM does. This changes a bunch of
things about how LLVM optimizes and inlines, so it may cause noticeable
changes in compile times, code size, and speed, either for better or for
worse. You can use the old pass manager (until LLVM removes it) by passing
-flegacy-pass-manager (and -Wl,--lto-legacy-pass-manager when doing LTO)
(note however that neither workaround affects the building of system
libraries, unless you modify emscripten or build them manually). (#13427)
- Removed use of Python multiprocessing library because of stability issues.
Added a new environment variable EM_PYTHON_MULTIPROCESSING=1 that can be set
to revert back to using Python multiprocessing, in case there are reports of
regressions (that variable is intended to be temporary). (#13493)
- Binaryen now always inlines single-use functions. This should reduce code size
and improve performance. If you prefer the old default, you can get that with
-sBINARYEN_EXTRA_PASSES=--one-caller-inline-max-function-size=1 (#13744).
- Fix generating of symbol files with --emit-symbol-map for JS targets.
When -s WASM=2 is used. Two symbols are generated:
- [name].js.symbols - storing Wasm mapping
- [name].wasm.js.symbols - storing JS mapping
In other cases a single [name].js.symbols file is created.
2.0.16: 03/25/2021
- Lists that are passed on the command line can now skip the opening an closing
braces, allowing for simpler, more readable settings. e.g.
-s EXPORTED_FUNCTIONS=foo,bar
- Remove/deprecate no longer used --llvm-opts command line option. Any
arguments not processed by emcc will be passed through to clang directly
these days.
- Values returned from sysconf now more closely match the definitions found in
header files and in upstream musl (#13713).
- DISABLE_EXCEPTION_CATCHING=2 is now deprecated since it can be inferred from
the presence of the EXCEPTION_CATCHING_ALLOWED list. This makes
DISABLE_EXCEPTION_CATCHING a simple binary option (0 or 1) which defaults to
0 which will be set to 1 internally if EXCEPTION_CATCHING_ALLOWED list is
specified.
- Values returned from pathconf now match the definitions found in header files
and/or upstream musl:
_PC_LINK_MAX 3200 -> 8
_PC_SYNC_IO -1 -> 1
_PC_REC_INCR_XFER_SIZE -1 -> 4096
_PC_REC_MAX_XFER_SIZE -1 -> 4096
_PC_SYMLINK_MAX -1 -> 255
- Added support for wrapping emcc and em++ via ccache: install Emscripten port
of ccache via emsdk, or from https://github.com/juj/ccache/tree/emscripten,
and run explicitly with "ccache emcc ..." after installing, or automatically
just with "emcc ..." after activating ccache via emsdk (#13498).
- Added support to use a custom set of substitution characters . # and ? to
ease passing arrays of C symbols on the command line to ASYNCIFY_* settings.
(#13477)
- In MINIMAL_RUNTIME build mode, errno support will now be disabled by default
due to the code size that it adds. (MINIMAL_RUNTIME=1 implies SUPPORT_ERRNO=0
by default) Pass -s SUPPORT_ERRNO=1 to enable errno support if necessary.
- Using EM_ASM and EM_JS in a side module will now result in an error (since
this is not implemented yet). This could effect users were previously
inadvertently including (but not actually using) EM_ASM or EM_JS functions in
side modules (#13649).
- Remove dependency on Uglify by finishing the rewrite of passes to acorn
(#13636, #13621).
- Primary development branch switched from master to main.
2.0.15: 03/05/2021
- Calls to newlocale (and new std::locale in C++) with arbirary names will
now succeed. This is the behaviour of musl libc which emscripten had
previously inadvertently disabled.
- System libraries are now compiled with debug info (-g). This doesn't
affect release builds (builds without -g) but allows DWARF debugging of
types defined in system libraries such as C++ STL types (#13078).
- uname machine field is now either wasm32 or wasm64 instead of x86-JS (#13440)
- Several pthreads exit-related fixes (#12985) (#10524).
- Fix IDBFS syncing with existing directories (#13574).
- Add libmodplug port and allow mod files to be played in SDL2 (#13478).
- emscripten_GetProcAddress is now part of libGL. Normally the change is not
noticeable, unless you build in STRICT mode and do not already have -lGL
to link in that library. If not, add -lGL. (#13524)
2.0.14: 02/14/2021
- Add new setting: REVERSE_DEPS. This can be used to control how emscripten
decides which reverse dependecies to include. See settings.js for more
information. The default setting ('auto') is the traditional way emscripten
has worked in the past so there should be no change unless this options is
actually used. This option partially replaces the EMCC_ONLY_FORCED_STDLIBS
environment variable which (among other things) essentially had the effect of
setting REVERSE_DEPS to be 'all'.
- Clang now performs loop unrolling when targeting WebAssembly at -O2 and
higher. It can be disabled using -fno-unroll-loops.
2.0.13: 01/19/2021
- Remove unused Browser.safeSetInterval and Browser.safeCallback. These
had no callers in emscripten itself or any testing. If there are users of
these functions we could re-enable them with some testing.
- Fix race condition when running many emcc processes after clearing the cache.
The processes would race to run the sanity checks and could interfere with
each other (#13299).
- Emscripten now builds a complete sysroot inside the EM_CACHE directory.
This includes the system headers which get copied into place there rather
than adding a sequence of extra include directories.
- Added support for -s MALLOC=emmalloc when -s MAXIMUM_MEMORY is more than 2GB.
(#13258)
- Add back support for calling the legacy dynCall_sig() API to invoke function
pointers to wasm functions from JavaScript. Pass -s DYNCALLS=1
to include that functionality in the build. This fixes a regression that
started in Aug 31st 2020 (Emscripten 2.0.2) in #12059. Also implement
support for dynCall() in MINIMAL_RUNTIME builds. (#13296)
- SDL2_ttf now uses upstream compiled with TTF_USE_HARFBUZ flag.
- The system for linking native libraries on demand (based on the symbols
present in input object files) has been removed. Libraries such as libgl,
libal, and libhtml5 are now included on the link line by default unless
-s AUTO_NATIVE_LIBRARIES=0 is used. This should not effect most builds
in any way since wasm-ld ignores unreferenced library files. Only users
of the --whole-archive linker flag (which is used when MAIN_MODULE=1 is
set) should be effected.
2.0.12: 01/09/2021
- emscripten/vr.h and other remnants of WebVR support removed. (#13210, which
is a followup to #10460)
- Stop overriding CMake default flags based on build type. This will
result in builds that are more like CMake does on other platforms. You
may notice that RelWithDebInfo will now include debug info (it did not
before, which appears to have been an error), and that Release will
use -O3 instead of -O2 (which is a better choice anyhow). (#13083)
2.0.11: 12/17/2020
- emcc -v no longer forces the running the sanity checks. Sanity checks
are always run on first use or can be forced with --check or by setting
EMCC_DEBUG is set in the environment.
- An upstream LLVM regression with global initializer linking has been fixed
(#13038).
- Remove a racy unneeded assertion about async dynamic linking (#13060).
2.0.10: 12/04/2020
- Fix handling of exit() in pthreads. (#12933)
- Added support for C11 thread API. (#9243)
- The WebAssembly memory used by emscripten programs is now, by default, created
in the wasm file and exported to JavaScript. Previously we could create the
memory in JavaScript and import it into the wasm file. The new
IMPORTED_MEMORY setting can be used to revert to the old behaviour.
Breaking change: This new setting is required if you provide a runtime
value for wasmMemory or INITIAL_MEMORY on the Module object.
- Internally, emscripten now uses the --sysroot argument to point clang at
it headers. This should not effect most projects but has a minor effect the
order of the system include paths: The root include path
(<emscritpen_root>/system/include) is now always last in the include path.
- Fix JS pthreads proxying + WASM_BIGINT (#12935)
- Optimize makeDynCall to use dynCall_xx function directly where needed (#12741)
2.0.9: 11/16/2020
- dlopen, in conformace with the spec, now checks that one of either RTDL_LAZY
or RTDL_NOW flags ar set. Previously, it was possible set nether of these
without generating an error.
- Allow -lSDL2_mixer to just work. (Others like -lSDL2 always worked, but
for SDL2_mixer things were broken because we build multiple variations of
that library.) That link flag is now the same as -s USE_SDL2_MIXER=2.
- Stack state is no longer stored in JavaScript. The following variables have
been replaced with native functions in <emscripten/stack.h>:
- STACK_BASE
- STACK_MAX
- STACKTOP
- TOTAL_STACK
- The ABI used for importing symbol by address in dynamic linking (MAIN_MODULE +
SIDE_MODULE) is now the same as the ABI used by llvm and wasm-ld. That is,
symbol addresses are imported from the 'GOT.mem' and 'GOT.func' pseudo
modules. As one side effect of this change it is now required that JavaScript
functions that are imported by address are now required to have a __sig
specified in the library JavaScript file.
- MODULARIZE + WASM_ASYNC_COMPILATION=0, that is, modularize mode but with
async compilation turned off, so that startup is synchronous, now returns the
Module object from the factory function (as it would not make sense to return
a Promise without async startup). See #12647
- Added experimental support for using emscripten as a post link tool. In this
case the input to emscripten is a single wasm file (for example the output of
wasm-ld). When emcc is run with --post-link it will take a wasm file as
input that perform all the normal post link steps such as finalizing and
optimizing the wasm file and generating the JavaScript and/or html that will
run it.
- Added emulation support and a build time warning for calling Wasm function
pointers from JS library files via the old syntax
{{{ makeDynCall('sig') }}} (ptr, arg1, arg2);
that was broken on Aug 31st 2020 (Emscripten 2.0.2). A build warning will now
be emitted if the old signature is used. Convert to using the new signature
{{{ makeDynCall('sig', 'ptr') }}} (arg1, arg2);
instead.
2.0.8: 10/24/2020
- -s ASSERTIONS=2 now implies -s STACK_OVERFLOW_CHECK=2. Previously only
-s ASSERTIONS=1 implied -s STACK_OVERFLOW_CHECK=1.
- Dynamic linking (MAIN_MODULE + SIDE_MODULE) now produces wasm binaries that
depend on mutable globals. Specifically the stack pointer global is mutable
and shared between the modules. This is an ABI change for dynamic linking.
(#12536)
- emcc now accepts --arg=foo as well as --arg foo. For example
--js-library=file.js.
- Reject promises returned from the factory function created by using the
MODULARIZE build option if initialization of the module instance fails
(#12396).
- emrun: Passing command line flags (arguments that start with -) to the
program bring run now requires a -- on the command line to signal the
end of emrun arguments. e.g:
emrun filename.html -- --arg-for-page
This is standard behaviour for command line parsing and simplifies the
emrun logic.
2.0.7: 10/13/2020
- Don't run Binaryen postprocessing for Emscripten EH/SjLj. This lets us avoid
running wasm-emscripten-finalize just for C++ exceptions or longjmp. This
is an ABI change. (#12399)
- Run SAFE_HEAP on user JS code using a new Acorn pass, increasing the
coverage of those tests to all JS in the output (#12450).
- EM_LOG_DEMANGLE is now deprecated. Function names shown in wasm backtraces
are never mangled (they are either missing or demangled already) so demangled
is not possible anymore.
- In STRICT mode we no longer link in C++ mode by default. This means if you
are building a C++ program in STRICT mode you need to link via em++ rather
than emcc. This matches the behaviour of gcc and clang.
- IDBFS now persists files whenever their timestamp changes; previously it acted
on sync only if the timestamp increased and ignored the file changes otherwise.
- When -s SUPPORT_LONGJMP=0 is passed to disable longjmp, do not run the LLVM
wasm backend path that handles longjmp. Before this only affected linking, and
now the flag gives you the ability to affect codegen at compile time too. This
is necessary if one does not want any invokes generated for longjmp at all.
(#12394)
2.0.6: 10/02/2020
- Add new COMPILER_WRAPPER settings (with corresponding EM_COMPILER_WRAPPER
environment variable. This replaces the existing EMMAKEN_COMPILER
environment variable which is deprecated, but still works for the time being.
The main differences is that EM_COMPILER_WRAPPER only wrapps the configured
version of clang rather than replacing it.
- ASAN_SHADOW_SIZE is deprecated. When using AddressSanitizer, the correct
amount of shadow memory will now be calculated automatically.
2.0.5: 09/28/2020
- Fix a rare pthreads + exceptions/longjmp race condition (#12056).
- Add WEBGL_multi_draw_instanced_base_vertex_base_instance bindings (#12282).
- Fix a rare pthreads main thread deadlock (that worsened in 2.0.2, but existed
before). (#12318)
- The WebAssembly table is now created and exported by the generated wasm
module rather then constructed by the JS glue code. This is an implemention
detail that should not affect most users, but reduces code size. (#12296)
- Add getentropy in sys/random.h, and use that from libc++'s
random_device. This is more efficient, see #12240.
- Fixed ABORT_ON_WASM_EXCEPTIONS to work with the recent dynCall changes where
functions can be called via the WASM table directly, bypassing WASM exports
(#12269).
- Add ASYNCIFY_ADVISE to output which functions have been instrumented for
Asyncify mode, and why they need to be handled. (#12146)
2.0.4: 09/16/2020
- First release with Bazel support.
- Stop including malloc and free by default. If you need access to them from
JS, you must export them manually using
-s EXPORTED_FUNCTIONS=['_malloc', ..].
- Stop running Binaryen optimizations in -O1. This makes -O1 builds a little
larger but they compile a lot faster, which makes more sense in a "compromise"
build (in between -O0 and higher optimization levels suitable for release
builds). (#12178)
- Add ERROR_ON_WASM_CHANGES_AFTER_LINK option that errors if we need to do
any work in wasm-emscripten-finalize or wasm-opt after linking. This
can verify the link is maximally fast and also does no DWARF rewriting.
(#12173)
2.0.3: 09/10/2020
- Breaking changes to calling Wasm function pointers from JavaScript:
1. It is no longer possible to directly call dynCall_sig(funcPtr, param) to
call a function pointer from JavaScript code. As a result, JavaScript code
outside all JS libraries (pre-js/post-js/EM_ASM/EM_JS/external JS code) can no
longer call a function pointer via static signature matching dynCall_sig, but
must instead use the dynamic binding function
dynCall(sig, ptr, args);
This carries a significant performance overhead. The function dynCall is not
available in -s MINIMAL_RUNTIME=1 builds.
2. old syntax for calling a Wasm function pointer from a JS library file used
to be
{{{ makeDynCall('sig') }}} (ptr, arg1, arg2);
This syntax will no longer work, and until Emscripten <2.0.9 causes
a runtime error TypeError: WebAssembly.Table.get(): Argument 0 must be
convertible to a valid number.
New syntax for calling Wasm function pointers from JS library files is
{{{ makeDynCall('sig', 'ptr') }}} (arg1, arg2);
See PR #12059 for details.
- The native optimizer and the corresponding config setting
(EMSCRIPTEN_NATIVE_OPTIMIZER) have been removed (it was only relevant to
asmjs/fastcomp backend).
- Remove ALLOC_DYNAMIC and deprecate dynamicAlloc. (#12057, which also
removes the internal DYNAMICTOP_PTR API.)
- Add ABORT_ON_WASM_EXCEPTIONS which will abort when an unhandled WASM exception
is encountered. This makes the Emscripten program behave more like a native
program where the OS would terminate the process and no further code can be
executed when an unhandled exception (e.g. out-of-bounds memory access) happens.
Once the program aborts any exported function calls will fail with a "program
has already aborted" exception to prevent calls into code with a potentially
corrupted program state.
- Use __indirect_function_table as the import name for the table, which is
what LLVM does.
- Remove BINARYEN_SCRIPTS setting.
- The default output format is now executable JavaScript. Previously we would
default to output objecting files unless, for example, the output name ended
in .js. This is contrary to behaviour of clang and gcc. Now emscripten
will always produce and executable unless the -c, -r or -shared flags
are given. This is true even when the name of the output file ends in .o.
e.g, emcc foo.c -o foo.o will produce a JavaScript file called foo.o.
This might surprise some users (although it matches the behavior of existing
toolchains) so we now produce a warning in this case.
2.0.2: 09/02/2020
- Simplify Fetch C API error handling: we used to check if the error code was
0 and switch that to 404, but that only really helps file:// URLs, which
are not very useful for testing anyhow for other reasons (like not working
in chrome), and it made things more complex. The behavior has been changed
to be simpler and just leave the browser's error code as it is.
- Enable --no-heap-copy file packager option by default, and remove the old
default behavior entirely. That is the behavior we should have had from the
beginning as it is more memory-efficient. (#12027)
- --no-entry is now required in STANDALONE_WASM mode when building a reactor
(application without a main function). Previously exporting a list of
functions that didn't include _main would imply this. Now the list of
EXPORTED_FUNCTIONS is not relevant in the deciding the type of application
to build. (#12020)
- Allow polymorphic types to be used without RTTI when using embind. (#10914)
- Do not remove __original_main using --inline-main. We used to do this
so that it didn't show up in stack traces (which could be confusing because
it is added by the linker - it's not in the source code). But this has had
several downsides, so we are stopping that now. This does not affect program
behavior, unless you look at the wasm internals. However, one noticeable
effect is that if you use ASYNCIFY_ADD or ASYNCIFY_ONLY then you may need
to add __original_main to there (since you are doing manual fine-tuning of
the list of functions, which depends on the wasm's internals). Note that this
should not matter in -O2+ anyhow as normal inlining generally removes
__original_main. (#11995)
2.0.1: 08/21/2020
- Change the default value of STACK_OVERFLOW_CHECK in builds with ASSERTIONS
from 2 to 1. This means that plain debug builds (-O0, which enables
ASSERTIONS) do not have the most expensive stack checks on by default. You
can still add them with -s STACK_OVERFLOW_CHECK=2.
- Remove the RESERVED_FUNCTION_POINTERS setting, which is no longer needed as
we have ALLOW_TABLE_GROWTH. The old option allowed a fixed number of
functions to be added to the table, while the new one allows an unlimited
number. (We needed the old option for fastcomp, which could not support
growth.) The old setting is mapped to the new one, so that building with
-s RESERVED_FUNCTION_POINTERS=K for any K > 0 will simply turn on
table growth. The only noticeable effect of this is that you will be able to
add an unlimited amount of functions and not just K.
2.0.0: 08/10/2020
- First release that only supports the new upstream wasm backend (which has been
the default for a long time) and no longer supports the old fastcomp backend.
(#11319)
- Python2 is no longer supported by Emscripten. Emsdk now includes a bundled
copy of Python3 on both macOS and Windows. This means that only non-emsdk
users and linux users should be affected by this change.
- Store exceptions metadata in wasm memory instead of JS. This makes exception
handling almost 100% thread-safe. (#11518)
1.40.1: 08/01/2020
- Last release that still has optional support for the old fastcomp backend.
The new upstream backend, which has been the default for a long time, will
be the only one supported from 2.0.0 and onward (#11319).
- Fix the WebGL2 regression in 1.40.0 due to #11738 (#11780).
- If input files don't have a known extension assume they are object files
(linker inputs) rather then source files. This matches gcc/clang behaviour.
See #10560.
1.40.0: 07/30/2020
- This release contains a WebGL2 regression due to #11738.
- The EM_CONFIG environment variable and --em-config command line option no
longer support a literal python string. Instead the name of a config file is
required. Since all config file settings are individually override-able using
EM_FOO this should be enough.
- Running emscripten under python2 is now deprecated. It will show up as a
warning (which can be disabled with -Wno-deprecated). Please update to
python3 as we hope to remove support completely in the next releaase.
1.39.20: 07/20/2020
- Remove the --save-bc command line option. This was specific to fastcomp,
which is deprecated, and for debugging purposes we already have EMCC_DEBUG
which saves all intermediate files.
- It is now an error if a function listed in the EXPORTED_FUNCTIONS list is
missing from the build (can be disabled via -Wno-undefined)
(ERROR_ON_UNDEFINED_SYMBOLS and WARN_ON_UNDEFINED_SYMBOLS no longer apply
to these symbols which are explicly exported).
- Support for pthreads with wasm2js (WASM=0; #11505).
- Rename emscripten/math.h to emscripten/em_math.h because if a user adds
emscripten/ as an include path with -I, that can override libc math.h,
which leads to very confusing errors.
1.39.19: 07/07/2020
- In standalone mode make main mandatory by default (#11536). To build a
library ("reactor"), use --no-entry. The compiler will suggest that if
main is not present.
- Automatically resume AudioContexts on user input in SDL and OpenAL (#10843).
- Asyncify now does liveness analysis to find which locals to save
(Binaryen#2890).
- Settings on the command line no longer require a space between the -s and
the name of the setting. For example, -sEXPORT_ALL is now equivalent to
-s EXPORT_ALL.
- Rename EXCEPTION_CATCHING_WHITELIST to EXCEPTION_CATCHING_ALLOWED. The
functionality is unchanged, and the old name will be allowed as an alias
for a few releases to give users time to migrate.
- Add support for the new add-list in Asyncify and update existing list names
following the updates in Binaryen, so that now we have ASYNCIFY_ADD to
add a function, ASYNCIFY_REMOVE to remove one (previously this was
called ASYNCIFY_BLACKLIST), and ASYNCIFY_ONLY to set a list of the
only functions to instrument and no others (previously this was called
ASYNCIFY_WHITELIST). The updated lists also handle indirect calls properly,
so that if you use ASYNCIFY_IGNORE_INDIRECT and then add (using either the
add-list or the only-list) all the functions that are on the stack when
pausing, then things will work (for more, see
https://github.com/WebAssembly/binaryen/pull/2913).
1.39.18: 06/12/2020
- Disable LIBCXX_ABI_OPTIMIZED_FUNCTION which is an ABI change in libc++
(changing the layout of the std::function object) (#11403).
- New WASM2C option that integrates with wabt's wasm2c tool in order to
compile everything into a single C file (#11213).
1.39.17: 06/05/2020
- Use Promise polyfill for MODULARIZE when supporting legacy browsers. (#11320)
- Fix minification of wasm2js output when using --emit-symbol-map. (#11279)
- On first use, emscripten creates a sample config file. This config file
is now created in the emscripten directory by default. The traditional
~/.emscripten config file in the $HOME directory is still supported and
the sample config will still be written there in the case that the emscripten
root is read-only.
- The default location for downloaded ports is now a directory called "ports"
within the cache directory. In practice these means by default they live
in cache/ports inside the emscripten source directory. This can be
controlled by setting the location of the cache directory, or for even more
fine grained control the EM_PORTS environment variable and the PORTS
config setting can be used.
- Added support for compiling SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE 4.2 and
128-bit wide AVX intrinsics, emulated on top of Wasm SIMD instruction set.
(#11193, #11243, #11290, #11327). Pass -msimd128 -msse to enable
targeting SSE.
- Removed obsolete SIMD.js support (-s SIMD=1). Use -msimd128 to target Wasm
SIMD. (#11180)
- Add warning about fastcomp deprecation (can be disabled via -Wno-fastcomp).
- The mmap method of JavaScript filesystem drivers (based on library_fs.js) no
longer takes a target memory. It's safer/cleaner/smaller to assume the target
is the global memory buffer.
- Remove emterpreter and EMTERPRETIFY settings. Emterpreter has largely
been replaced by asyncify and is fastcomp only so due for removing in
the near future anyway.
- Upgrade various musl string functions to 1.2 to fix aliasing issues. (#11215)
1.39.16: 05/15/2020
- Add Math C API for direct access to JavaScript Math object (#11151).
- Address Sanitizer support now includes JavaScript as well, that is, memory
access of HEAP* arrays is checked by ASan. That allows errors to be found if
JS glue code does something wrong like forget to shift a pointer. To use this,
just build with ASan normally, -fsanitize=address at link (#11147).
- Fix embind string conversions in multithreaded builds (#10844).
- ALLOW_MEMORY_GROWTH used to silently disable ABORTING_MALLOC. It now
just changes the default, which means you can pass -s ABORTING_MALLOC=1 to
override the default, which was not possible before. (If you pass the flag
and don't want that behavior, stop passing the flag.) (#11131)
- Change the factory function created by using the MODULARIZE build option to
return a Promise instead of the module instance. That is, beforehand
Module()
would return an instance (which was perhaps not ready yet if startup was
async). In the new model, that returns a Promise which you can do .then or
await on to get notified when the instance is ready, and the callback
receives the instance. Note that both before and after this change
doing Module() creates and runs an instance, so the only change is
the return value from that call.
This fixes some long-standing bugs with that option which have been reported
multiple times, but is a breaking change - sorry about that. To reduce the
risk of confusing breakage, in a build with ASSERTIONS we will show a clear
warning on common errors. For more, see detailed examples for the current
usage in src/settings.js on MODULARIZE. (#10697)
- A new PRINTF_LONG_DOUBLE option allows printf to print long doubles at full
float128 precision. (#11130)
- emscripten_async_queue_on_thread has been renamed to
emscripten_dispatch_to_thread which no longer implies that it is async -
the operation is in fact only async if it is sent to another thread, while it
is sync if on the same one. A new emscripten_dispatch_to_thread_async
function is added which is always async.
- The emscripten cache now lives in a directory called cache at the root
of the emscripten tree by default. The CACHE config setting and the
EM_CACHE environment variable can be used to override this (#11126).
- Honor CACHE setting in config file as an alternative to EM_CACHE
environment variable.
- Remove --cache command line arg. The CACHE config setting and the
EM_CACHE environment variable can be used to control this.
- Compiling to a file with no suffix will now generate an executable (JS) rather
than an object file. This means simple cases like emcc -o foo foo.c do the
expected thing and generate an executable.
- System libraries such as libc and libc++ are now included by default at
link time rather than selectively included based on the symbols used in the
input object files. For small programs that don't use any system libraries
this might result in slightly slower link times with the old fastcomp
backend. In order to exclude these libraries build with -nostdlib and/or
-nostdlib++.
1.39.15: 05/06/2020
- Add --extern-pre-js and --extern-post-js emcc flags. Files provided there
are prepended/appended to the final JavaScript output, after all other
work has been done, including optimization, optional MODULARIZE-ation,
instrumentation like SAFE_HEAP, etc. They are the same as prepending/
appending those files after emcc finishes running, and are just a convenient
way to do that. (For comparison, --pre-js and --post-js optimize that code
together with everything else, keep it in the same scope if running
MODULARIZE, etc.).
- Stop defining FE_INEXACT and other floating point exception macros in libc,
since we don't support them. That also prevents musl from including code using
pragmas that don't make sense for wasm. Ifdef out other uses of those pragmas
as well, as tip of tree LLVM now fails to compile them on wasm. (#11087)
- Update libcxx and libcxxabi to LLVM 10 release branch (#11038).
- Remove BINARYEN_PASSES setting (#11057). We still have
BINARYEN_EXTRA_PASSES (the removed setting completely overrides the set
of passes from the command line, which doesn't make much sense as some of
them are mandatory like setting the sbrk ptr).
- Remove MODULARIZE_INSTANCE build option (#11037). This was a seldom used
option that was complicating the logic for MODULARIZE. Module instances can
be created by using MODULARIZE and calling the factory function explicitly.
See the new --extern-post-js option added in this release, which can help
code that used MODULARIZE_INSTANCE (you can add an extern post js which
does Module = Module(); for example).
1.39.14: 05/01/2020
- Update SDL2 to latest in ports, which has recently been updated to include
upstream 2.0.10.
- Add warning on use of EMTERPRETIFY which is soon to be removed.
- Emscripten can now compile assembly files in llvm's .s/.S file format.
- Remove test-only environment variable handling for EMCC_LEAVE_INPUTS_RAW.
The two uses cases in our test code were covered by the -nostdlib option.
- Remove untested CONFIGURE_CC. This could be used to override the underlying
compiler used in emcc/em++ but only during configure tests. There are other
ways to control/fake the detected configure features that don't require such
monkey patching. For example setting defaults via a site file:
https://www.gnu.org/software/autoconf/manual/autoconf-2.67/html_node/Site-Defaults.html
- Remove undocumented and untested config settings: COMPILER_OPTS. This was
a global setting in the emscripten config file that would inject extra
compiler options.
- Allow spaces in a path to Python interpreter when running emscripten from Unix
shell (#11005).
- Support atexit() in standalone mode (#10995). This also fixes stdio stream
flushing on exit in that mode.
v1.39.13: 04/17/2020
- Support for WebAssembly BigInt integration with a new WASM_BIGINT flag. With
that the VM will use a JS BigInt for a wasm i64, avoiding the need for JS
legalization. See #10860.
- Add another value for ENVIRONMENT named 'webview' - it is a companion
option for 'web' and enables some additional compatibility checks
so that generated code works both in normal web and in a webview like Cordova.
See #10846
v1.39.12: 04/09/2020
- Pass linker flags directly to wasm-ld by default. We still filter out certain
flags explicitly. If there are other flags that it would be useful for us
to ignore we can add them to the list of ignored flags.
- Optionally support 2GB+ heap sizes. To do this we make the JS code have unsigned
pointers (we need all 32 bits in them now), which can slightly increase code
size (>>> instead of >>). This only happens when the heap size may be over
2GB, which you must opt into explicitly, by setting MAXIMUM_MEMORY to a
higher value (i.e. by default you do not get support for 2GB+ heaps).
See #10601
- --llvm-lto flag is now ignored when using the upstream llvm backend.
With the upstream backend LTO is controlled via -flto.
- Require format string for emscripten_log.
- Program entry points without extensions are now shell scripts rather than
python programs. See #10729. This means that python emcc no longer works.
However emcc, emcc.py and python emcc.py all continue to work.
The reason for this change is that #!/usr/bin/env python is no longer
portable since the python symlink was dropped from Ubuntu 20.04.
- New EM_IMPORT macro to mark C/C++ symbols as imported from outside the module
(i.e. imported from JS). Currently we still default to assuming that all
undefined symbols can come from JS, but in the future we hope to mark such
symbols explicitly to allow the linker to report on genuinely undefined
symbols.
- Dynamic linking optimizations: Stop emitting unnecessary fp$ and g$
accessors in main modules, possible in Binaryen thanks to ensuring function
table indexes are unique (#10741).
- New JS_MATH option to use Math.* in JS instead of compiled musl (#10821).
- Pass Module to Module callback functions like Module.preRun (#10777).
- Support not having ports, for packagers of emscripten that don't want
them (#10810).
- Rename syscalls to have meaningful names (#10750).
v1.39.11: 03/20/2020
- The default c++ version is no longer fixed at c++03. We now fall back to
clang's default which is currently c++14.
- Remove arc4random function form library.js. This is a BSD-only library
function. Anyone requiring BSD compat should be able to use something like
https://libbsd.freedesktop.org/.
- Change the meaning of ASYNCIFY_IMPORTS: it now contains only new imports
you add, and does not need to contain the list of default system imports like
emscripten_sleep. There is no harm in providing them, though, so this
is not a breaking change.
- Enable DWARF support: When compiling with -g, normal DWARF emitting happens,
and when linking with -g we preserve that and update it. This is a change
from before, where we assumed DWARF was unneeded and did not emit it, so this
can increase the size of debug builds (i.e. builds compiling and/or linking
with -g). This change is necessary for full debugging support, that is, to
be able to build with -g and use a debugger. Before this change only the
-gforce_dwarf flag enabled DWARF; that flag is now removed. If you want
the old behavior, build your object files with -gline-tables-only (that will
only add line table info, which is just enough for things like source maps and
does not include full debug info). For more info and background see #10325.
- Remove hacks from memset handling, in particular, in the wasm backend,
completely remove the JS version of memset from the JS library and from
DEFAULT_LIBRARY_FUNCS_TO_INCLUDE. The regular C version will be linked in
from compiler_rt normally. A noticeable difference you may see is that
a JS library cannot add a __dep to memset - deps only work for JS
library functions, but now we only have the regular C version. If you hit that
issue, just add _memset to EXPORTED_FUNCTIONS (or adjust
deps_info.json).
- Minimal runtime code size optimizations, see #10725, #10724, #10663.
- wasm2js fix for a long-existing but very rare correctness bug, see #10682.
- Use atomics in musl lock/unlock in pthreads builds, which may fix very rare
pthreads + stdio issues (none have been reported though). See #10670.
v1.39.10: 03/09/2020
- Fix a SIMD regression in 1.39.9 (#10658).
- Fix emscripten_atomic_exchange_u8,16,32,64 (#10657).
- Switch bzip2 to an emscripten-ports mirror.
v1.39.9: 03/05/2020
- Add support for -Wall, -Werror, -w, -Wno-error=, -Werror=, for controlling
internal emscripten errors. The behavior of these flags matches the gcc/clang
counterparts.
- Rename TOTAL_MEMORY to INITIAL_MEMORY and WASM_MEM_MAX to MAXIMUM_MEMORY,
which are more accurate and match wasm conventions. The old names are still
supported as aliases.
- Updated of libc++abi and libc++ to llvm 9.0.0 (#10510)
- Refactor syscall interface: Syscalls are no longer variadic (except those
that are inherently such as open) and no longer take the syscall number as
arg0. This should be invisible to most users but will effect any external
projects that try to implement/emulate the emscripten syscall interface.
See #10474
- Removed src/library_vr.js, as it was outdated and nonfunctional, and the WebVR
specification has been obsoleted in favor of the upcoming WebXR specification.
(#10460)
- Deprecate WASM_OBJECT_FILES setting. There are many standard ways to enable
bitcode objects (-flto, -flto=full, -flto=thin, -emit-llvm).
- Removed EmscriptenWebGLContextAttributes::preferLowPowerToHighPerformance
option that has become unsupported by WebGL. Access
EmscriptenWebGLContextAttributes::powerPreference instead. (#10505)
- When implementing forwarding function aliases in JS libraries, either the
alias or the target function must contain a signature annotation. (#10550)
- Add a check in Asyncify builds with ASSERTIONS that we do not have
compiled code on the stack when starting to rewind, which is dangerous.
- Implement libc system() for node.js (#10547).
- Standalone mode improvements, time (#10530, #10536), sysconf (#10535),
getpagesize (#10533), _Exit (#10534)
- Fix many closure compiler warnings (e.g. #10525).
- Avoid unnecessary syscall proxying (#10511).
- Added new link time command line option -jsDfoo=val to allow specifying
custom preprocessor options to JS library files. (#10624, #10580)
v1.39.8: 02/14/2020
- Add LLD_REPORT_UNDEFINED option that should allow for more detailed
diagnostics when symbols are undefined at link time. This currently has
some limitations and is not enabled by default. For example, EM_JS symbols
are reported as undefined at link time, as are __invoke_* functions.
- wasm2js optimizations. See binaryen#2623.
- WebGPU Compute fixes. Simple examples now work. See #10367.
- Many DWARF debug info fixes. Emitting of DWARF is correct as far as we know,
including when optimizing (a few passes are disabled for now, but almost all
work). We still only generate it behind the -gforce_dwarf flag for now,
though (but that should be removed soon).
v1.39.7: 02/03/2020
- The checked-in copy of the Closure compiler was removed in favor of getting it
from npm. This means that developers now need to run npm install after
checking out emscripten if they want to use closure (--closure). emsdk users
are not effected because emsdk runs this as a post install step (#9989).
- Added support for specifying JSDoc minification annotations for Closure in
JS library, pre and post files. See
https://github.com/google/closure-compiler/wiki/Annotating-JavaScript-for-the-Closure-Compiler
(#10272)
- Add new Fibers API for context switching, that supersedes the old coroutine
API that only ran on fastcomp. See #9859
- Added new linker option -s WASM=2 which produces a dual Wasm+JS build, which
falls back to using a JavaScript version if WebAssembly is not supported in
target browser/shell. (#10118)
- Added new linker option -s CLOSURE_WARNINGS=quiet|warn|error that allows aborting
the build if the Closure compiler produced any warnings.
v1.39.6: 01/15/2020
- Development has switched from the "incoming" branch to "master".
- Added new system header <emscripten/heap.h>, which enables querying information
about the current WebAssembly heap state.
- Reduced default geometric memory overgrowth rate from a very generous 2x factor
to a more memory conserving +20% factor, and capped maximum reservation to 96MB
at most.
- Added options MEMORY_GROWTH_GEOMETRIC_STEP and MEMORY_GROWTH_GEOMETRIC_CAP
to allow customizing the heap growth rates.
- Renamed MEMORY_GROWTH_STEP option to MEMORY_GROWTH_LINEAR_STEP option.
- Added new linker option -s HTML5_SUPPORT_DEFERRING_USER_SENSITIVE_REQUESTS=0
(default enabled) to allow disabling support for deferred fullscreen mode and
pointer lock requests for applications that do not need deferring support.
v1.39.5: 12/20/2019
- Added support for streaming Wasm compilation in MINIMAL_RUNTIME (off by default)
- All ports now install their headers into a shared directory under
EM_CACHE. This should not really be a user visible change although one
side effect is that once a given port is built, its headers are then
universally accessible, just like the library is universally available as
-l<name>.
- Removed timestamp field from mouse, wheel, devicemotion and
deviceorientation events. The presence of a timestamp on these events was
slightly arbitrary, and populating this field caused a small profileable
overhead that all users might not care about. It is easy to get a timestamp of
an event by calling emscripten_get_now() or emscripten_performance_now()
inside the event handler function of any event.
- Add fine-grained options for specific legacy browser support,
MIN_FIREFOX_VERSION, MIN_SAFARI_VERSION, MIN_IE_VERSION,
MIN_EDGE_VERSION, MIN_CHROME_VERSION. The existing LEGACY_VM_SUPPORT
option sets all of them to 0, that is, maximal backwards compatibility.
Note that going forward, we will use these settings in more places, so if
you do need very old legacy browser support, you may need to set either
LEGACY_VM_SUPPORT or the fine-grained options. For more details see #9937
- Default DISABLE_DEPRECATED_FIND_EVENT_TARGET_BEHAVIOR to 1. See #9895.
With this change the old deprecated HTML5 API event target lookup behavior is
disabled. There is no "Module.canvas" object, no magic "null" default handling,
and DOM element 'target' parameters are taken to refer to CSS selectors, instead
of referring to DOM IDs. For more information see:
https://groups.google.com/forum/#!msg/emscripten-discuss/xScZ_LRIByk/_gEy67utDgAJ
- WASI API updated from wasi_unstable to wasi_snapshot_preview1. This
is mostly an implementation detail, but if you use STANDALONE_WASM it means
that the output of emscripten now requires a runtime with
wasi_snapshot_preview1 support.
- SAFE_STACK has been removed, as it overlaps with STACK_OVERFLOW_CHECK.
Replace SAFE_STACK=1 with STACK_OVERFLOW_CHECK=2 (note the value is 2).
This also has the effect of enabling stack checking on upstream builds when
ASSERTIONS are enabled (as assertions enable STACK_OVERFLOW_CHECK=2).
v1.39.4: 12/03/2019
- Remove deprecated requestFullScreen method from library_browser.js, please
use requestFullscreen (without the capital S).
- Remove deprecated requestFullScreen and cancelFullScreen from library_glut.js
- Remove deprecated requestFullScreen and cancelFullScreenfrom library_glfw.js
- Fix SDL2_mixer support for ogg vorbis. See #9849
- Various source maps fixes, see #9926 #9882 #9837 #9814
v1.39.3: 11/14/2019
v1.39.2: 11/06/2019
- Archives with missing indexes will now have ranlib run on them automatically
at link time. This avoids linker errors when using GNU ar to build archive
files.
- ERROR_ON_MISSING_LIBRARIES now also applies to internal symbols that start
with emscripten_. Prior to this change such missing symbols would result
in a runtime error, now they are reported at compile time.
- Pthread blocking on the main thread will now warn in the console. If
ALLOW_BLOCKING_ON_MAIN_THREAD is unset then the warning is an error.
- Add pthread_tryjoin_np, which is a POSIX API similar to pthread_join
but without blocking.
- New function emscripten_has_asyncify().
- Add support for pthreads in Node.js, using Node Workers. See #9745
v1.39.1: 10/30/2019
- Only MEMFS is included by default, others (NODEFS, IDBFS, WORKERFS, PROXYFS)
must be linked in explicitly, using -lnodefs.js, -lidbfs.js',
-lworkerfs.js, -lproxyfs.js. See #9645
v1.39.0: 10/18/2019
- The emsdk defaults to the upstream backend (instead of fastcomp) from this
release onward (but both backends are still fully supported). See
https://emscripten.org/docs/compiling/WebAssembly.html#backends
- Add support for overriding .emscripten config variables using environment
variables. Any config variable FOO can be overridden by EM_FOO in the
environment.
- -Werror now also turns warnings in the python driver code into errors.
- Internal settings have moved from settings.js to settings_internal.js.
These are settings that are for internal use only and are not set-able from
the command line. If we misclassified any of these please open a bug.
- STANDALONE_WASM mode now supports setting up argv via wasi APIs.
- STANDALONE_WASM mode now supports running static constructors in _start.
v1.38.48: 10/11/2019
- Add support for MAIN_THREAD_EM_ASM in wasm backend. #9560
- Add ability to disable FETCH worker in Fastcomp backend via
USE_FETCH_WORKER=0. This is useful for people who use FETCH, but don't
perform any synchronous fetches on the main thread. #9567
- Remove EMCONFIGURE_JS. Since #6269 we have set it to "2" which means never
use native, always use JS.
v1.38.47: 10/02/2019
- Add support for FETCH API in WASM backend. This doesn't support FETCH in the
main thread (USE_FETCH_WORKER=0 is enforced). #9490
- Redefine errno values to be consistent with wasi. This will let us avoid
needing to convert the values back and forth as we use more wasi APIs.
This is an ABI change, which should not be noticeable from user code
unless you use errno defines (like EAGAIN) and keep around binaries
compiled with an older version that you link against. In that case, you
should rebuild them. See #9545.
- Removed build option -s ONLY_MY_CODE as we now have much better solutions
for that, like building to a wasm object file or using STANDALONE_WASM
etc. (see
https://github.com/emscripten-core/emscripten/wiki/WebAssembly-Standalone).
- Emscripten now supports the config file (.emscripten) being placed in the
emscripten directory rather that the current user's home directory.
See #9543
v1.38.46: 09/25/2019
- Rename libpthreads to libpthread to match its normal name on other platforms.
This change should be completely internal to emscripten.
- Remove redundant COMPILER_ENGINE and JS_ENGINE options. We only support
node as the compiler engine so just use a single NODE_JS option for that.
- Module.abort is no longer exported by default. It can be exported in the normal
way using EXTRA_EXPORTED_RUNTIME_METHODS, and as with other such changes in
the past, forgetting to export it will show a clear error in ASSERTIONS mode.
- Remove EMITTING_JS flag, and replace it with STANDALONE_WASM. That flag indicates
that we want the wasm to be as standalone as possible. We may still emit JS in
that case, but the JS would just be a convenient way to run the wasm on the Web
or in Node.js.
- ASYNCIFY_BLACKLIST and ASYNCIFY_WHITELIST now support simple '*' wildcard matching
v1.38.45: 09/12/2019
v1.38.44: 09/11/2019
- Remove Binaryen from the ports system. This means that emscripten will
no longer automatically build Binaryen from source. Instead, either use
the emsdk (binaries are provided automatically, just like for LLVM), or
build it yourself and point BINARYEN_ROOT in .emscripten to it. See #9409
v1.38.43: 08/30/2019
- noExitRuntime is no longer a property on the Module object. Use noExitRuntime
instead of Module.noExitRuntime.
v1.38.42: 08/19/2019
- Add support for address sanitizer
and standalone leak sanitizer
with multiple threads. (#9060, #9076)
- Remove ERROR_ON_MISSING_LIBRARIES setting (it's always on now)
- Remove the ability to use Python operators in flags that support KB/MB/GB/TB
suffixes, e.g. TOTAL_MEMORY. This means that -s TOTAL_MEMORY=1024*1024
will no longer work. This is done because the mechanism may result in
execution of arbitrary code via command line flags.
v1.38.41: 08/07/2019
- Remove fastcomp's implementation of Asyncify. This has been deprecated for
a long time, since we added Emterpreter-Async, and now we have a new Asyncify
implementation in the upstream wasm backend. It is recommended to upgrade to
the upstream backend and use Asyncify there if you need it. (If you do still
need the older version, you can use 1.38.40.)
- Drop ExitStatus from inheriting from Error(), as that could capture the whole
global scope, preventing temporary variables at page startup from being garbage
collected. (#9108)
- __builtin_return_address now requires -s USE_OFFSET_CONVERTER=1 to work. (#9073)
- emrun now uses HTTP/1.1 instead of HTTP/1.0.
- callMain is no longer exported by default on Module, to allow better JS
minification. You must add it to EXTRA_EXPORTED_RUNTIME_METHODS if you want
to call it on Module. (In assertions builds, an error with an explanation is
shown.)
- Allow expressions with side effects as EM_ASM's arguments and prohibit
non-arithmetic arguments (e.g. pointers, functions, arrays, objects). (#9054)
- emcc on Windows now uses native newline byte sequence to get a line to
print for parse error reporting. (#9088)
- Internal API update: one can now specialize embind's (un)marshalling for a
group of types via SFINAE, instead of a single type. (#9089)
- Options passed on the Module object during startup, like Module.arguments,
are now copied to a local (in order to avoid writing Module.* everywhere,
which wastes space). You can still provide them as always, but you can't
modify Module.arguments and other things after startup (which is now
after we've finished processing them). In a build with assertions enabled you
will get an error if you access those properties after startup. (#9072)
v1.38.40: 07/24/2019
- LLVM backend pthread builds no longer use external memory initialization
files, replacing them with passive data segments.
- LLVM backend now supports thread local storage via the C extension __thread
and the C11/C++11 keyword thread_local. (#8976)
- Internal API change: Move read, readAsync, readBinary, setWindowTitle from
the Module object to normal JS variables. If you use those internal APIs,
you must change Module.readAsync()/Module['readAsync']() to readAsync().
Note that read is also renamed to read_ (since "read" is an API call in
the SpiderMonkey shell). In builds with ASSERTIONS, an error message is
shown about the API change. This change allows better JS minification
(the names read, readAsync etc. can be minified, and if the variables are
not used they can be removed entirely). Defining these APIs on Module
(which was never documented or intended, but happened to work) is also
no longer allowed (but you can override read_ etc. from JS).
v1.38.39: 07/16/2019
- Add support for address sanitizer. (#8884)
- Currently, only supports one thread without dynamic linking.
- Rename Bysyncify (the name used during development) to Asyncify. This keeps
the name consistent with the old ASYNCIFY flag, no need for a new one, as
they basically do the same thing.
v1.38.38: 07/08/2019
- Add support for standalone leak sanitizer. (#8711)
v1.38.37: 06/26/2019
- Set ENV['LANG'] following the user's preferred language (HTTP Accept-Language / navigator.languages[0])
- emscripten_run_script_string now returns C NULL instead of the string null
or undefined when the result of the eval is JavaScript null or undefined.
- Add a new system for managing system libraries. (#8780)
This may require minor changes when performing certain operations:
- When using embuilder.py to build a specific library, the name may have
changed: for consistency, all library names are prefixed with lib now.
- embuilder.py now only builds the requested library, and not its dependencies
and certain system libraries that are always built. For example, running
embuilder.py build libc no longer builds libcompiler_rt if it hasn't be built.
- When using EMCC_FORCE_STDLIBS with a list of libraries, you must now use
the simplified names, for example, libmalloc and libpthreads instead of
libdlmalloc or libpthreads_stub. These names will link in the correct
version of the library: if the build is configured to use emmalloc, libmalloc
will mean libemmalloc, and if thread support is disabled, libpthreads will
mean libpthreads_stub. This allows you to say libmalloc or libpthreads without
worrying about which implementation is supposed to be used, and avoid duplicate
symbols if you used the wrong implementation.
- LLVM wasm backend pthreads fixes, see #8811, #8718
v1.38.36: 06/15/2019
v1.38.35: 06/13/2019
- Include some waterfall fixes
for the emsdk builds on linux regarding libtinfo.
- NOTE: due to a CI failure, builds for mac and windows were not generated.
v1.38.34: 06/01/2019
- Add support for undefined behavior sanitizer.
- This allows emcc -fsanitize=undefined to work. (#8651)
- The minimal runtime (-fsanitize-minimal-runtime) also works. (#8617)
v1.38.33: 05/23/2019
- First release to use the new chromium build infrastructure
https://groups.google.com/forum/#!msg/emscripten-discuss/WhDtqVyW_Ak/8DfDnfk0BgAJ
- Add emscripten_return_address which implements the functionality of
gcc/clang's __builtin_return_address. (#8617)
v1.38.32: SKIPPED
- The transition from the old to the new CI occurred around here. To avoid
ambiguity while both CIs were still generating builds, we just tagged a new
one (1.38.33) on the new CI and skipped 1.38.32.
- The transition also moves all builds and downloads away from the old
mozilla-games infrastructure to the new chromium ones. As a result all links
to mozilla-games URLs will not work (these were never documented, but could
be seen from the internals of the emsdk; the new emsdk uses the proper new
URLs, so you can either use the sdk normally or find the URLs from there).
v1.38.31: 04/24/2019
- Change ino_t/off_t to 64-bits. (#8467)
- Add port for bzip2 library (libbz2.a). (#8349)
- Add port for libjpeg library. (#8361)
- Enable ERROR_ON_MISSING_LIBRARIES by default (#8461)
v1.38.30: 03/21/2019
- Remove Module.buffer which was exported by default unnecessarily. This was an
undocumented internal detail, but in theory, code may have relied on it.
(#8277)
v1.38.29: 03/11/2019
v1.38.28: 02/22/2019
- Option -s EMTERPRETIFY_WHITELIST now accepts shell-style wildcards;
this allows matching static functions with conflicting names that
the linker distinguishes by appending a random suffix.
- Normalize mouse wheel delta in library_browser.js. This changes the scroll
amount in SDL, GLFW, and GLUT. (#7968)
v1.38.27: 02/10/2019
- Change how EMCC_LOCAL_PORTS works, to be more usable. See #7963
- Remove deprecated Pointer_stringify (use UTF8ToString instead). See #8011
- Added a new option -s DISABLE_DEPRECATED_FIND_EVENT_TARGET_BEHAVIOR=1 that
changes the lookup semantics of DOM elements in html5.h event handler
callbacks and WebGL context creation. The new behavior is to use CSS selector
strings to look up DOM elements over the old behavior, which was somewhat
ad hoc constructed rules around default Emscripten uses. The old behavior
will be deprecated and removed in the future. Build with -s ASSERTIONS=1
to get diagnostics messages related to this transition.
- Breaking change with -s USE_PTHREADS=1 + -s FETCH=1: When building with
-o a.html, the generated worker script is now named "a.fetch.js" according
to the base name of the specified output, instead of having a fixed name
"fetch-worker.js".
v1.38.26: 02/04/2019
- Fix some pthreads proxying deadlocks. See #7865
v1.38.25: 01/18/2019
- Move kripken/emscripten,emscripten-fastcomp,emscripten-fastcomp-clang to
emscripten-core/*
v1.38.24: 01/17/2019
- Perform JS static allocations at compile time (#7850)
v1.38.23: 01/10/2019
- Remove BINARYEN_METHOD: no more support for interpret modes, and if you want
non-wasm, use WASM=0.
- Support specifying multiple possible ENVIRONMENTs (#7809)
v1.38.22: 01/08/2019
- Add Regal port. See #7674
- System libraries have been renamed to include the lib prefix. If you use
EMCC_FORCE_STDLIBS or EMCC_ONLY_FORCED_STDLIBS to select system libraries
you may need to add the lib prefix.
- Rename pthread-main.js to NAME.worker.js, where NAME is the main
name of your application, that is, if you emit program.js then you'll get
program.worker.js (this allows more than one to exist in the same
directory, etc.).
- Dynamic linker has been taught to handle library -> library dependencies.
v1.38.21: 11/30/2018
- fastcomp: Remove runPostSets function and replace with normal static
constructor function. See #7579
v1.38.20: 11/20/2018
- Remove SPLIT_MEMORY option.
- Move getTempRet0/setTempRet0 to be JS library functions rather than
auto-generated by fastcomp.
- Change strptime()'s handling of the "%c" to match that of strftime().
This is a breaking change for code which depends on the old definition of
"%c".
v1.38.19: 11/15/2018
v1.38.18: 11/08/2018
- Wasm dynamic linking: Rename tableBase/memoryBase to
__table_base/__memory_base (#7467)
v1.38.17: 11/07/2018
- Minify wasm import and export names. This decreases JS and wasm size by
minifying the identifiers where JS calls into wasm or vice versa, which
are not minifiable by closure or other JS-only tools. This happens in
-O3, -Os and above. See #7431
v1.38.16: 11/02/2018
- Breaking change: Do not automatically set EXPORT_ALL for MAIN_MODULES or
SIDE_MODULES. This means that you must explicitly export things that will
be called from outside (normally, on EXPORTED_FUNCTIONS), or
you can manually enable EXPORT_ALL yourself (which returns to the exact
same behavior as before). This change brings us in line with more standard
dynamic linking, and will match what the LLVM wasm backend will have.
See #7312.
- Invalid -s flags on the command line are now treated as errors.
- Remove BUILD_AS_SHARED_LIBRARY setting.
v1.38.15: 10/25/2018
v1.38.14: 10/22/2018
- Errors are now reported when functions listed in EXPORTED_FUNCTIONS are not
defined. This can be disabled via ERROR_ON_UNDEFINED_SYMBOLS=0. See #7311.
v1.38.13: 10/10/2018
- Support -s NO_X=1 as an alias for -s X=0 and vice versa, which
simplifies current settings with NO_-prefixed names. See #7151.
- Various EMULATED_FUNCTION_POINTER improvements. See #7108, #7128.
- ERROR_ON_UNDEFINED_SYMBOLS is now the default. See #7196
v1.38.12: 09/03/2018
- Update SDL2 to 2.0.7. See #7016.
- Optionally build using native object files (wasm backend only).
For now this is behind a new option flag: -s WASM_OBJECT_FILES=1.
See #6875.
v1.38.11: 08/02/2018
- Support for loading wasm files in the same dir as the JS file, using
node.js/Web-specific techniques as applicable. See #5368 and followups.
- Add an API for async side module compilation in wasm. See #6663.
- Remove builtin Crunch support. See #6827.
v1.38.10: 07/23/2018
- Change the type of size_t and friends from int to long. This may have
noticeable effects if you depend on the name mangling of a function that uses
size_t (like in EXPORTED_FUNCTIONS), and you must rebuild source files to
bitcode (so your bitcode is in sync with the system libraries after they are
rebuilt with this change). Otherwise this should not have any noticeable
effects for users. See #5916.
v1.38.9: 07/22/2018
- Fix Module.locateFile to resolve relative paths to *.wasm, *.mem and other
files relatively to the main JavaScript file rather than the current working
directory (see #5368).
- Add second argument prefix to Module.locateFile function that contains
the path to the JavaScript file where files are loaded from by default.
- Remove Module.*PrefixURL APIs (use Module.locateFile instead).
v1.38.8: 07/06/2018
- Fix a regression in 1.38.7 with binaryen no longer bundling binaryen.js
(which emscripten doesn't need, that's just for handwritten JS users, but
emscripten did check for its presence).
v1.38.7: 07/06/2018
- Correctness fix for stack handling in invoke_*()s. This may add noticeable
overhead to programs using C++ exceptions and (less likely) setjmp/longjmp -
please report any issues. See #6666 #6702
- Deprecate Module.ENVIRONMENT: Now that we have a compile-time option to set
the environment, also having a runtime one on Module is complexity that we
are better off without. When Module.ENVIRONMENT is used with ASSERTIONS it
will show an error to direct users to the new option (-s ENVIRONMENT=web , or
node, etc., at compile time).
- Breaking change: Do not export print/printErr by default. Similar to other
similar changes (like getValue/setValue). We now use out() and err()
functions in JS to print to stdout/stderr respectively. See #6756.
v1.38.6: 06/13/2018
v1.38.5: 06/04/2018
- Update libc++ to 6.0, bringing c++17 support (std::byte etc.)
v1.38.4: 05/29/2018
- Fix asm.js validation regression from 1.38.2.
v1.38.3: 05/25/2018
- Upgrade to LLVM 6.0.1.
v1.38.2: 05/25/2018
- Add ENVIRONMENT option to specify at compile time we only need JS to support
one runtime environment (e.g., just the web). When emitting HTML, set that to
web so we emit web code only. #6565
- Regression in asm.js validation due to cttz optimization #6547
v1.38.1: 05/17/2018
- Remove special-case support for src/struct_info.compiled.json: Make it a
normal cached thing like system libraries, not something checked into the
source tree.
- Breaking change: Emit WebAssembly by default. Only the default is changed -
we of course still support asm.js, and will for a very long time. But
changing the default makes sense as the recommended output for most use cases
should be WebAssembly, given it has shipped in all major browsers and
platforms and is more efficient than asm.js. Build with -s WASM=0 to
disable wasm and use asm.js if you want that (or use -s LEGACY_VM_SUPPORT=1, which emits output that can run in older browsers,
which includes a bunch of polyfills as well as disables wasm). (#6419)
v1.38.0: 05/09/2018
v1.37.40: 05/07/2018
- Fix regression in 1.37.39 on -s X=@file parsing (see #6497, #6436)
v1.37.39: 05/01/2018
- Regression: Parsing of -s X=@file broke if the file contains a newline
(see #6436; fixed in 1.37.40)
v1.37.38: 04/23/2018
- Breaking change: Simplify exception handling, disabling it by default.
Previously it was disabled by default in -O1 and above and enabled in -O0,
which could be confusing. You may notice this change if you need exceptions
and only run in -O0 (since if you test in -O1 or above, you'd see you need to
enable exceptions manually), in which case you will receive an error at
runtime saying that exceptions are disabled by default and that you should
build with -s DISABLE_EXCEPTION_CATCHING=0 to enable them.
- Fix regression in 1.37.37 on configure scripts on MacOS (see #6456)
v1.37.37: 04/13/2018
- Regression: configure scripts on MacOS may be broken (see #6456; fixed in 1.37.38)
v1.37.36: 03/13/2018
v1.37.35: 02/23/2018
- MALLOC option, allowing picking between dlmalloc (previous allocator and
still the default) and emmalloc, a new allocator which is smaller and
simpler.
- Binaryen update that should fix all known determinism bugs.
v1.37.34: 02/16/2018
- addFunction is now supported on LLVM wasm backend, but when being used on
the wasm backend, you need to provide an additional second argument, a Wasm
function signature string. Each character within a signature string
represents a type. The first character represents the return type of a
function, and remaining characters are for parameter types.
- 'v': void type
- 'i': 32-bit integer type
- 'j': 64-bit integer type (currently does not exist in JavaScript)
- 'f': 32-bit float type
- 'd': 64-bit float type
For asm.js and asm2wasm you can provide the optional second argument, but it
isn't needed. For that reason this isn't a breaking change, however,
providing the second argument is recommended so that code is portable across
all backends and modes.
v1.37.33: 02/02/2018
v1.37.32: 01/31/2018
v1.37.31: 01/31/2018
- LLVM and clang updates from upstream (5.0svn, close 5.0 release).
v1.37.30: 01/31/2018
v1.37.29: 01/24/2018
v1.37.28: 01/08/2018
- Breaking change: Don't export the ALLOC_* numeric constants by default. As
with previous changes, a warning will be shown in -O0 and when ASSERTIONS
are on if they are used.
- Breaking change: Don't export FS methods by default. As with previous
changes, a warning will be shown in -O0 and when ASSERTIONS are on, which
will suggest either exporting the specific methods you need, or using
FORCE_FILESYSTEM which will auto export all the main filesystem methods.
Aside from using FS methods yourself, you may notice this change when using a
file package created standalone, that is, by running the file packager
directly and then loading it at run time (as opposed to telling emcc to
package the files for you, in which case it would be aware of them at compile
time); you should build with FORCE_FILESYSTEM to ensure filesystem support
for that case.
v1.37.27: 12/24/2017
- Breaking change: Remove the Runtime object, and move all the useful methods
from it to simple top-level functions. Any usage of Runtime.func should be
changed to func.
v1.37.26: 12/20/2017
- Breaking change: Change NO_EXIT_RUNTIME to 1 by default. This means that by
default we don't include code to shut down the runtime, flush stdio streams,
run atexits, etc., which is better for code size. When ASSERTIONS is on, we
warn at runtime if there is text buffered in the streams that should be
flushed, or atexits are used.
- Meta-DCE for JS+wasm: remove unused code between JS+wasm more aggressively.
This should not break valid code, but may break code that depended on unused
code being kept around (like using a function from outside the emitted JS
without exporting it - only exported things are guaranteed to be kept alive
through optimization).
v1.37.24: 12/13/2017
- Breaking change: Similar to the getValue/setValue change from before (and
with the same ASSERTIONS warnings to help users), do not export the
following runtime methods by default: ccall, cwrap, allocate,
Pointer_stringify, AsciiToString, stringToAscii, UTF8ArrayToString,
UTF8ToString, stringToUTF8Array, stringToUTF8, lengthBytesUTF8, stackTrace,
addOnPreRun, addOnInit, addOnPreMain, addOnExit, addOnPostRun,
intArrayFromString, intArrayToString, writeStringToMemory,
writeArrayToMemory, writeAsciiToMemory.
v1.37.23: 12/4/2017
- Breaking change: Do not polyfill Math.{clz32, fround, imul, trunc} by
default. A new LEGACY_VM_SUPPORT option enables support for legacy
browsers. In ASSERTIONS mode, a warning is shown if a polyfill was needed,
suggesting using that option.
- Breaking change: Do not export getValue/setValue runtime methods by default.
You can still use them by calling them directly in code optimized with the
main file (pre-js, post-js, js libraries; if the optimizer sees they are
used, it preserves them), but if you try to use them on Module then you
must export them by adding them to EXTRA_EXPORTED_RUNTIME_METHODS. In -O0
or when ASSERTIONS is on, a run-time error message explains that, if they
are attempted to be used incorrectly.
v1.37.17: 7/25/2017
- Updated to libc++'s "v2" ABI, which provides better alignment for string data
and other improvements. This is an ABI-incompatible change, so bitcode files
from previous versions will not be compatible.

with respect to reading debug symbol names in Wasm callstacks. Use of the new
Names section format first shipped in Emscripten 1.37.10, Binaryen version
32, Firefox 55, Firefox Nightly 2017-05-18 and Chrome 59; earlier versions
still used the old format. For more information, see
