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:
