>From 9de8a92c3bcda9d1fa414b9b355cb8ac77ae0812 Mon Sep 17 00:00:00 2001 From: Joseph Huber <hube...@outlook.com> Date: Fri, 11 Oct 2024 14:53:17 -0500 Subject: [PATCH] [HIP] Replace use of `llvm-mc` with `clang` Summary: We currently use `llvm-mc` which is intended for internal testing and not expected to be present in every installation. This patch changes that to just use clang instead to get the `.o` from the HIP registration code. My preferred solution would be to use the new driver, but I still haven't gotten the test suite to pass on this one weird OpenMP case.
