a45f713c - add option to instantiate templates already in the PCH

Sun, 19 Apr 2020 15:49:47 +0000

add option to instantiate templates already in the PCHAdd -fpch-instantiate-templates which makes template instantiations beperformed already in the PCH instead of it being done in every singlefile that uses the PCH (but every single file will still do it as wellin order to handle its own instantiations). 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-exprs.cpp

[c++20] Implement P1009R2: allow omitting the array bound in an arraynew expression.This was voted into C++20 as a defect report resolution, so weretroactively apply it to all prior language modes (though it can neveractually be used before C++11 mode).llvm-svn: 360006 List of files: /llvm-project-15.0.7/clang/test/PCH/cxx-exprs.cpp

Deserialize the direct-initialization range of a "new" expressionproperly. Previously, we deserialized it but failed to set thecorresponding member in CXXNewExpr. Fixes .llvm-svn: 150963 List of files: /llvm-project-15.0.7/clang/test/PCH/cxx-exprs.cpp
