Hopefully we can do better before landing. Posting for discussion.
Didn't learn a huge amount. spirv rejects the clang::amdgpu_kernel annotation and I can't work out how that's supposed to be spelled.
Libc doesn't do anything with address spaces which upsets spirv (unlike openmp which does lots)
The libc build streams bitcode through lld which refuses to do anything with it, but that can be patched.
Port is mostly copying the amdgpu folders to spirv64. Not happy with cmake assuming that spirv64 means amdgpu but also don't understand how to stop it making that assumption.
Lots of libm seems to be dead. I'm hoping Joseph will delete said dead code as it makes this patch look excessively large.
Also doesn't seem ideal to have copy&pasted the config entrypoints stuff.
Don't have a loader, probably reasonable to write one that calls llvm to jit spirv though.
