I can see 20-30% buildtime saved with the few tests I've tried.The change may reorder compiler output and also generated code, butshould be generally safe and produce functionally identical code.There are some rare cases that do not compile with it,such as test/PCH/pch-instantiate-templates-forward-decl.cpp. Iftemplate instantiation bailed out instead of reporting the error,these instantiations could even be postponed, which would make themwork.Enable this by default for clang-cl. MSVC creates PCHs by compilingthem using an empty .cpp file, which means templates are instantiatedwhile building the PCH and so the .h needs to be self-contained,making test/PCH/pch-instantiate-templates-forward-decl.cpp to failwith MSVC anyway. So the option being enabled for clang-cl matches this.Differential Revision: https://reviews.llvm.org/D69585 List of files: /llvm-project-15.0.7/clang/test/PCH/cxx-dependent-sized-ext-vector.cpp Sun, 19 Apr 2020 15:49:47 +0000 Luboš Luňák <l.lunak@centrum.cz> http://172.16.0.5:8080/history/llvm-project-15.0.7/clang/test/PCH/cxx-dependent-sized-ext-vector.cpp#00aee437 [Serialization] Serialize DependentSizedExtVectorTyperdar://30659700Differential Revision: https://reviews.llvm.org/D31134llvm-svn: 298493 List of files: /llvm-project-15.0.7/clang/test/PCH/cxx-dependent-sized-ext-vector.cpp Wed, 22 Mar 2017 10:04:48 +0000 Alex Lorenz <arphaman@gmail.com>
