SPIR-V portability fix for single element vectors #719

Closed linehill closed 9 months ago

linehill commented 9 months ago

Adjust a HIP header for avoiding single element vectors to appear in LLVM IR. Single element vectors are not supported in SPIR-V without an extension (e.g. SPV_INTEL_vector_compute) which are enabled with hard coded --spirv-ext=+all option in clang.

I'll make clang patch to disable all SPIR-V extension which will cause an assertion to be triggered in llvm-spirv if there are single element vectors in the input device code.

Related to issue #713.

(We had this patch previously but it got lost in #521)

Let's add also to 1.1.
