When save-temps is enabled and the given offload-archs differ only in target features with the same arch, the intermediate postlink.bc and postopt.bc files were getting overwritten. This fix, suffixes the intermediate file names with the complete TargetID. E.g. `helloworld.amdgcn-amd-amdhsa.gfx90a:xnack+.postlink.bc` and `helloworld.amdgcn-amd-amdhsa.gfx90a:xnack+.postopt.bc` >From e83a9d37633dbc069ed6a0e00ed84e5a03402208 Mon Sep 17 00:00:00 2001 From: Saiyedul Islam <saiyedul.is...@amd.com> Date: Wed, 17 Jul 2024 08:04:59 -0500 Subject: [PATCH] [ClangLinkerWrapper] Fix intermediate file naming for multi-arch compilation When save-temps is enabled and the given offload-archs differ only in target features with the same arch, the intermediate postlink.bc and postopt.bc files were getting overwritten.
