Introduction
============
The SPIR-V target provides code generation for the SPIR-V binary format described
in `the official SPIR-V specification <https://www.khronos.org/registry/SPIR-V/>`_.

Target Triples
==============
For cross-compilation into SPIR-V use option
``-target <Architecture><Subarchitecture>-<Vendor>-<OS>-<Environment>``
to specify the target triple:
.. table:: SPIR-V Architectures
============ ==============================================================
Architecture Description
============ ==============================================================
``spirv32`` SPIR-V with 32-bit pointer width.
``spirv64`` SPIR-V with 64-bit pointer width.
============ ==============================================================
.. table:: SPIR-V Subarchitectures
=============== ==============================================================
Subarchitecture Description
=============== ==============================================================
*<empty>* SPIR-V version deduced by tools based on the compiled input.
``v1.0`` SPIR-V version 1.0.
``v1.1`` SPIR-V version 1.1.
``v1.2`` SPIR-V version 1.2.
``v1.3`` SPIR-V version 1.3.
``v1.4`` SPIR-V version 1.4.
``v1.5`` SPIR-V version 1.5.
=============== ==============================================================
.. table:: SPIR-V Vendors
===================== ==============================================================
Vendor Description
===================== ==============================================================
*<empty>*/``unknown`` Generic SPIR-V target without any vendor-specific settings.
===================== ==============================================================
.. table:: Operating Systems
===================== ============================================================
OS Description
===================== ============================================================
*<empty>*/``unknown`` Defaults to the OpenCL runtime.
===================== ============================================================
.. table:: SPIR-V Environments
===================== ==============================================================
Environment Description
===================== ==============================================================
*<empty>*/``unknown`` Defaults to the OpenCL environment.
===================== ==============================================================
Example:
``-target spirv64v1.0`` can be used to compile for SPIR-V version 1.0 with 64-bit pointer width.
