[clang] [clang] Don't use -Wno-nested-anon-types on GCC (PR #95029)
https://github.com/Endilll approved this pull request. `-Wnested-anon-types` isn't supported even by GCC 7.4, so yeah, thank you for fixing this. https://github.com/llvm/llvm-project/pull/95029 ___ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
[clang] [clang] Don't use -Wno-nested-anon-types on GCC (PR #95029)
llvmbot wrote: @llvm/pr-subscribers-clang Author: Martin Storsjö (mstorsjo) Changes GCC usually doesn't warn about unrecognized -Wno-foo options, if no diagnostics are printed. However if some diagnostics are printed, it also mentions that there were unrecognized -Wno-foo options. Before 4feae05c6abda364a9295aecfa600d7d4e7dfeb6, we checked for whether -Wnested-anon-types was supported, and added the -Wno-foo form if the positive form of the option was supported. As of GCC 14, -Wnested-anon-types isn't supported, thus limit the use of the option to actual Clang (and still only while using the GCC compatible driver). This avoids unnecessary mentions about unrecognized -Wno-foo options when building with GCC. --- Full diff: https://github.com/llvm/llvm-project/pull/95029.diff 1 Files Affected: - (modified) clang/CMakeLists.txt (+3-1) ``diff diff --git a/clang/CMakeLists.txt b/clang/CMakeLists.txt index 2ac0bccb42f50..2b5269f2ce2e7 100644 --- a/clang/CMakeLists.txt +++ b/clang/CMakeLists.txt @@ -350,7 +350,9 @@ if (LLVM_COMPILER_IS_GCC_COMPATIBLE) set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -pedantic -Wno-long-long") endif () - set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wno-nested-anon-types" ) + if (CMAKE_CXX_COMPILER_ID MATCHES "Clang") +set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wno-nested-anon-types" ) + endif () endif () # Determine HOST_LINK_VERSION on Darwin. `` https://github.com/llvm/llvm-project/pull/95029 ___ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
