URL: https://github.com/llvm/llvm-project/commit/83cb8bd4c9b17d031d6a4519d74c76650e850427 DIFF: https://github.com/llvm/llvm-project/commit/83cb8bd4c9b17d031d6a4519d74c76650e850427.diff LOG: [Clang] Enable UBSan for AMDGPU device offload (#219973) Summary: This enables the device UBSan runtime for AMDGPU devices. Primarily this required modifications to the `addSanitizerRuntime` interface so we can query the compilation's offload status. Also need to forward it through the linker wrapper interface. Works on all AMDGPU offload, slight hacks around the other targets as they do not advertise sanitizer runtimes properly. This is linked in via a new `-u __ubsan_offload_init` hook to pull in the side library. This is standard behavior and keeps the core logic mostly unchanged and re-used. --- <sub>Stack created with <a href="https://github.com/github/gh-stack";>GitHub Stacks CLI</a> • <a href="https://gh.io/stacks-feedback";>Give Feedback 💬</a></sub> Added: clang/test/Driver/Inputs/resource_dir_with_amdgpu_per_target_subdir/lib/amdgpu-amd-amdhsa/libclang_rt.ubsan_standalone.a clang/test/Driver/Inputs/resource_dir_with_amdgpu_per_target_subdir/lib/x86_64-unknown-linux-gnu/libclang_rt.ubsan_offload.a clang/test/Driver/Inputs/resource_dir_with_amdgpu_per_target_subdir/lib/x86_64-unknown-linux-gnu/libclang_rt.ubsan_standalone.a clang/test/Driver/fsanitize-undefined-offload.c Modified: clang/include/clang/Driver/CommonArgs.h clang/lib/Driver/ToolChains/AMDGPU.cpp clang/lib/Driver/ToolChains/Clang.cpp clang/lib/Driver/ToolChains/CommonArgs.cpp clang/lib/Driver/ToolChains/Cuda.cpp clang/lib/Driver/ToolChains/Cygwin.cpp clang/lib/Driver/ToolChains/FreeBSD.cpp clang/lib/Driver/ToolChains/Fuchsia.cpp clang/lib/Driver/ToolChains/Gnu.cpp clang/lib/Driver/ToolChains/Haiku.cpp clang/lib/Driver/ToolChains/Hexagon.cpp clang/lib/Driver/ToolChains/NetBSD.cpp clang/lib/Driver/ToolChains/OpenBSD.cpp clang/lib/Driver/ToolChains/Solaris.cpp clang/lib/Driver/ToolChains/UEFI.cpp Removed: ################################################################################ diff --git a/clang/include/clang/Driver/CommonArgs.h b/clang/include/clang/Driver/CommonArgs.h index f631cdbd23d03..6ba7657e283b8 100644 --- a/clang/include/clang/Driver/CommonArgs.h +++ b/clang/include/clang/Driver/CommonArgs.h @@ -57,7 +57,7 @@ void renderDebugInfoCompressionArgs(const llvm::opt::ArgList &Args, void claimNoWarnArgs(const llvm::opt::ArgList &Args);
