<!--LLVM PR SUMMARY COMMENT--> @llvm/pr-subscribers-clang-driver Author: Rainer Orth (rorth) <details> <summary>Changes</summary> `clang` currently fails to find a GCC installation on Linux/sparc64 with `-m32`. `strace` reveals that `clang` tries to access `/usr/lib/gcc/sparcv9-linux-gnu` (which doesn't exist) instead of `/usr/lib/gcc/sparc64-linux-gnu`. It turns out that 20d497c26fc95c80a1bacb38820d92e5f52bec58 was overeager in removing some of the necessary directories. Fixed by reverting the Linux/sparc* part of the patch. Tested on `sparc64-unknown-linux-gnu`. --- Full diff: https://github.com/llvm/llvm-project/pull/98124.diff 1 Files Affected: - (modified) clang/lib/Driver/ToolChains/Gnu.cpp (+4-2) ``````````diff diff --git a/clang/lib/Driver/ToolChains/Gnu.cpp b/clang/lib/Driver/ToolChains/Gnu.cpp index b141e5f2adfab..ff5e4022a2763 100644 --- a/clang/lib/Driver/ToolChains/Gnu.cpp +++ b/clang/lib/Driver/ToolChains/Gnu.cpp @@ -2563,9 +2563,11 @@ void Generic_GCC::GCCInstallationDetector::AddDefaultGCCPrefixes( "riscv64-unknown-elf"}; static const char *const SPARCv8LibDirs[] = {"/lib32", "/lib"}; - static const char *const SPARCv8Triples[] = {"sparcv8-linux-gnu"}; + static const char *const SPARCv8Triples[] = {"sparc-linux-gnu", + "sparcv8-linux-gnu"}; static const char *const SPARCv9LibDirs[] = {"/lib64", "/lib"}; - static const char *const SPARCv9Triples[] = {"sparcv9-linux-gnu"}; + static const char *const SPARCv9Triples[] = {"sparc64-linux-gnu", + "sparcv9-linux-gnu"}; static const char *const SystemZLibDirs[] = {"/lib64", "/lib"}; static const char *const SystemZTriples[] = { `````````` </details> https://github.com/llvm/llvm-project/pull/98124 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
