# 2a3b86c1	17-Jun-2020	Richard Smith <[email protected]>	Fix rejects-valid when referencing an implicit operator== from within a templated class. When a defaulted operator<=> results in the injection of a defaulted operator==, that operator== can be named Fix rejects-valid when referencing an implicit operator== from within a templated class. When a defaulted operator<=> results in the injection of a defaulted operator==, that operator== can be named by unqualified name within the same class, even if the class is templated. To make this work, perform the transform from defaulted operator<=> to defaulted operator== in the template definition context instead of the template instantiation context. This results in our substituting into a declaration from a context where we don't have a full list of template arguments (or indeed any), for which we are now more careful to not spuriously instantiate declarations that are not dependent on the arguments we're substituting. show more ...

# a45f713c	19-Apr-2020	Luboš Luňák <[email protected]>	add option to instantiate templates already in the PCH Add -fpch-instantiate-templates which makes template instantiations be performed already in the PCH instead of it being done in every single fi add option to instantiate templates already in the PCH Add -fpch-instantiate-templates which makes template instantiations be performed already in the PCH instead of it being done in every single file that uses the PCH (but every single file will still do it as well in order to handle its own instantiations). I can see 20-30% build time saved with the few tests I've tried. The change may reorder compiler output and also generated code, but should 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. If template instantiation bailed out instead of reporting the error, these instantiations could even be postponed, which would make them work. Enable this by default for clang-cl. MSVC creates PCHs by compiling them using an empty .cpp file, which means templates are instantiated while building the PCH and so the .h needs to be self-contained, making test/PCH/pch-instantiate-templates-forward-decl.cpp to fail with MSVC anyway. So the option being enabled for clang-cl matches this. Differential Revision: https://reviews.llvm.org/D69585 show more ...

We need to perform unqualified lookups from the context of a defaulted comparison, but not until we implicitly define the function, at which point we can't do those lookups any more. So perform the lookup from the end of the class containing the =default declaration and store the lookup results on the defaulted function until we synthesize the body. show more ...
