[PATCH] D77885: AMDGPU: Search for new ROCm bitcode library structure

[Yaxun Liu via Phabricator via cfe-commits]

yaxunl added a comment.

If we really want to do this, device lib change and hipcc change need to be ready. Since once this is committed without corresponding device lib and hipcc change, HIP will break.

On ROCM, device lib is currently installed at /opt/rocm/lib with extension .amdgcn.bc. This change requires device libs to be installed to /opt/rocm/amdgcn/bitcode and with extension .bc (drop amdgcn in extension). Also -device-lib-path option needs to point to /opt/rocm/amdgcn/bitcode or dropped.

On Windows, device lib Makefiles need to be changed to drop amdgcn in extension.

Another issue: is /opt/rocm/amdgcn/bitcode the right installation path for device lib? Shouldn't it be /opt/rocm/lib/amdgcn/bitcode or /opt/rocm/lib/amdgcn ?
