  "message": "Reland HIP offload PGO compiler support and link the device-profile runtime (#201607)\n\nThis mostly relands the compiler part of #177665 (approved and merged,\nthen reverted in #201416). The first commit restores it as merged: the\nAMDGPU instrumentation in LLVM and the HIP codegen in Clang.\n\n#177665 was reverted because of a Windows CRT problem, fixed by\nsplitting the ROCm runtime into a separate library clang_rt.profile_rocm\n(see the compiler-rt PR). The second commit links that library on the\nhost for HIP device PGO, in addOffloadRTLibs for the Linux and MSVC\ntoolchains, gated on HIP + profiling + the library being present. It is\na superset of clang_rt.profile and is linked first, so the base library\nstays inert. Non-HIP links are unaffected.\n\nDepends on the compiler-rt PR that adds clang_rt.profile_rocm.",
