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/cxx11-enum-template.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/cxx11-enum-template.cpp#b13eb8dc Allow -verify directives to be filtered by preprocessing.This is accomplished by making VerifyDiagnosticsConsumer a CommentHandler,which then only reads the -verify directives that are actually in liveblocks of code. It also makes it simpler to handle -verify directives thatappear in header files, though we still have to manually reparse some filesdepending on how they are generated.This requires some test changes. In particular, all PCH tests now have their-verify directives outside the "header" portion of the file, using the @linesyntax added in r159978. Other tests have been modified mostly to make itclear what is being tested, and to prevent polluting the expected output withthe directives themselves.Patch by Andy Gibbs! (with slight modifications)The new Frontend/verify-* tests exercise the functionality of this commit,as well as r159978, r159979, and r160053 (Andy's other -verify enhancements).llvm-svn: 160068 List of files: /llvm-project-15.0.7/clang/test/PCH/cxx11-enum-template.cpp Wed, 11 Jul 2012 19:58:23 +0000 Jordan Rose <jordan_rose@apple.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/clang/test/PCH/cxx11-enum-template.cpp#4b38ded6 Instantiating a class template should not instantiate the definition of anyscoped enumeration members.
