URL: https://github.com/llvm/llvm-project/commit/41bcfe81742ed6462096ccb42aa5f2b9d67027fc DIFF: https://github.com/llvm/llvm-project/commit/41bcfe81742ed6462096ccb42aa5f2b9d67027fc.diff LOG: [AIX] Define _ARCH_PPC64 macro for 32-bit %%% The macro _ARCH_PPC64 is already defined for 64-bit, but this patch defines it for 32-bit on AIX to follow xlc. See: https://www.ibm.com/docs/en/xl-c-and-cpp-aix/13.1.0?topic=features-macros-related-architecture-settings Note: This change creates a discrepancy between GCC, which defines _ARCH_PPC64 only for 64-bit mode. Tested with SPEC. %%% Reviewed By: cebowleratibm Differential Revision: https://reviews.llvm.org/D107244 Added: Modified: clang/lib/Basic/Targets/PPC.cpp clang/test/Preprocessor/init-ppc.c Removed: ################################################################################ diff --git a/clang/lib/Basic/Targets/PPC.cpp b/clang/lib/Basic/Targets/PPC.cpp index 4ee7282c06ce..711ba2837a9b 100644 --- a/clang/lib/Basic/Targets/PPC.cpp +++ b/clang/lib/Basic/Targets/PPC.cpp @@ -257,6 +257,9 @@ void PPCTargetInfo::getTargetDefines(const LangOptions &Opts, Builder.defineMacro("__powerpc64__"); Builder.defineMacro("__ppc64__"); Builder.defineMacro("__PPC64__"); + } else if (getTriple().isOSAIX()) { + // The XL compilers on AIX define _ARCH_PPC64 for both 32 and 64-bit modes. + Builder.defineMacro("_ARCH_PPC64"); } if (getTriple().isOSAIX()) { Builder.defineMacro("__THW_PPC__"); diff --git a/clang/test/Preprocessor/init-ppc.c b/clang/test/Preprocessor/init-ppc.c index abf2e919cff6..fedc1b6c9140 100644 --- a/clang/test/Preprocessor/init-ppc.c +++ b/clang/test/Preprocessor/init-ppc.c @@ -391,6 +391,7 @@ // PPC-AIX-NOT:#define __64BIT__ 1 // PPC-AIX:#define _AIX 1 // PPC-AIX:#define _ARCH_PPC 1 +// PPC-AIX:#define _ARCH_PPC64 1 // PPC-AIX:#define _BIG_ENDIAN 1 // PPC-AIX:#define _IBMR2 1 // PPC-AIX:#define _LONG_LONG 1 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
