URL: https://github.com/llvm/llvm-project/commit/d7c6794aff6625c420a719d64402827cbae55292 DIFF: https://github.com/llvm/llvm-project/commit/d7c6794aff6625c420a719d64402827cbae55292.diff LOG: [OpenMP] [cmake] Don't use -fno-semantic-interposition on Windows (#81113) This was added in 4b7beab4187ab0766c3d7b272511d5751431a8da. When the flag was added implicitly elsewhere, it was added via llvm/cmake/modules/HandleLLVMOptions.cmake, where it wasn't added on Windows/Cygwin targets. This avoids one warning per object file in OpenMP. (cherry picked from commit 72f04fa0734f8559ad515f507a4a3ce3f461f196) Added: Modified: openmp/cmake/HandleOpenMPOptions.cmake Removed: ################################################################################ diff --git a/openmp/cmake/HandleOpenMPOptions.cmake b/openmp/cmake/HandleOpenMPOptions.cmake index 71346201129b68..9387d9b3b0ff75 100644 --- a/openmp/cmake/HandleOpenMPOptions.cmake +++ b/openmp/cmake/HandleOpenMPOptions.cmake @@ -46,7 +46,11 @@ append_if(OPENMP_HAVE_WEXTRA_FLAG "-Wno-extra" CMAKE_C_FLAGS CMAKE_CXX_FLAGS) append_if(OPENMP_HAVE_WPEDANTIC_FLAG "-Wno-pedantic" CMAKE_C_FLAGS CMAKE_CXX_FLAGS) append_if(OPENMP_HAVE_WMAYBE_UNINITIALIZED_FLAG "-Wno-maybe-uninitialized" CMAKE_C_FLAGS CMAKE_CXX_FLAGS) -append_if(OPENMP_HAVE_NO_SEMANTIC_INTERPOSITION "-fno-semantic-interposition" CMAKE_C_FLAGS CMAKE_CXX_FLAGS) +if (NOT (WIN32 OR CYGWIN)) + # This flag is not relevant on Windows; the flag is accepted, but produces warnings + # about argument unused during compilation. + append_if(OPENMP_HAVE_NO_SEMANTIC_INTERPOSITION "-fno-semantic-interposition" CMAKE_C_FLAGS CMAKE_CXX_FLAGS) +endif() append_if(OPENMP_HAVE_FUNCTION_SECTIONS "-ffunction-section" CMAKE_C_FLAGS CMAKE_CXX_FLAGS) append_if(OPENMP_HAVE_DATA_SECTIONS "-fdata-sections" CMAKE_C_FLAGS CMAKE_CXX_FLAGS) _______________________________________________ llvm-branch-commits mailing list llvm-branch-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-branch-commits
