User Guide for SPIR-V Target¶
Introduction¶
The SPIR-V target provides code generation for the SPIR-V binary format described in the official SPIR-V specification.
Target Triples¶
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.
