Add 'amdgcn' (additionally to/instead of 'amd') Product: gcc Version: 13.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: target Assignee: unassigned at gcc dot gnu.org Reporter: burnus at gcc dot gnu.org CC: ams at gcc dot gnu.org, jakub at gcc dot gnu.org Target Milestone: --- I note that GCC has in gcc/config/gcn/t-omp-device: echo kind: gpu > $@ echo arch: gcn >> $@ echo isa: fiji gfx900 gfx906 gfx908 >> $@ That is, GCC supports as context selector: match(construct={target},device={arch(gcn)}) In contrast, llvm has, e.g. in clang/lib/Headers/openmp_wrappers/cmath: #pragma omp begin declare variant match(device = {arch(amdgcn)}) Thus: LLVM uses 'amdgcn'. Expected: arch = 'amdgcn' (also) works in GCC for better compatibility. I did not find a documentation and I think either variant is fine – albeit 'amdgcn' seems to be more natural. ^ permalink raw reply [flat|nested] 3+ messages in thread
