The SPIR-V target provides code generation for the SPIR-V binary format described in the official SPIR-V specification.
For cross-compilation into SPIR-V use option
-target <Architecture><Subarchitecture>-<Vendor>-<OS>-<Environment>
to specify the target triple:
SPIR-V Architectures Architecture Description spirv32 SPIR-V with 32-bit pointer width. spirv64 SPIR-V with 64-bit pointer width.
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.
SPIR-V Vendors Vendor Description <empty>/unknown Generic SPIR-V target without any vendor-specific settings.
Operating Systems OS Description <empty>/unknown Defaults to the OpenCL runtime.
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.
