Hmm I tried to fiddle around with this but I'm out of my depth here. Pulling in @MaskRay @compnerd @phosek in the hopes that one of you is able to provide some insight or pull in someone else who is able to help. When building a static compiler-rt with thinlto every downstream target breaks because of the missing `__extendxftf2` and `__trunctfxf2`. AFAIU this blocks everyone from using thinlto with compiler-rt. ld.lld: error: undefined symbol: __extendxftf2 >>> referenced by extendsftf2.c:18 (./external/llvm-project-overlay~17-init-bcr.0~llvm_project_overlay~llvm-project/compiler-rt/lib/builtins/extendsftf2.c:18) >>> lto.tmp:(__extendsftf2) >>> referenced by extenddftf2.c:18 (./external/llvm-project-overlay~17-init-bcr.0~llvm_project_overlay~llvm-project/compiler-rt/lib/builtins/extenddftf2.c:18) >>> lto.tmp:(__extenddftf2) >>> referenced by floattitf.c:75 (./external/llvm-project-overlay~17-init-bcr.0~llvm_project_overlay~llvm-project/compiler-rt/lib/builtins/floattitf.c:75) >>> lto.tmp:(__floattitf) >>> referenced 1 more times >>> did you mean: __extenddftf2 >>> defined in: lto.tmp ld.lld: error: undefined symbol: __trunctfxf2 >>> referenced by trunctfsf2.c:17 (./external/llvm-project-overlay~17-init-bcr.0~llvm_project_overlay~llvm-project/compiler-rt/lib/builtins/trunctfsf2.c:17) >>> lto.tmp:(__trunctfsf2) >>> referenced by trunctfdf2.c:17 (./external/llvm-project-overlay~17-init-bcr.0~llvm_project_overlay~llvm-project/compiler-rt/lib/builtins/trunctfdf2.c:17) >>> lto.tmp:(__trunctfdf2) bazel-out/k8-fastbuild-ST-1b2103630309/bin/external/llvm-project-overlay~17-init-bcr.0~llvm_project_overlay~llvm-project/clang/clang-linker-wrapper: error: 'ld.lld' failed I also vaguely remember this leading to issues with static CUDA linking, but I don't have stacktraces for that :/ Repository: rG LLVM Github Monorepo CHANGES SINCE LAST ACTION https://reviews.llvm.org/D53608/new/ https://reviews.llvm.org/D53608 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
