commit dd8297b0669f8e69b03ba40171b195b5acf0f963 Author: Richard Smith <richard@metafoo.co.uk> Date: Fri Oct 30 18:30:56 2020 -0700 PR42513: Fix handling of function definitions lazily instantiated from friends. When determining whether a function has a template instantiation pattern, look for other declarations of that function that were instantiated from a friend function definition, rather than assuming that checking for member specialization information on whichever declaration name lookup found will be sufficient. clang/include/clang/AST/Decl.h | 14 +++- clang/lib/AST/Decl.cpp | 61 ++++++++++++-- clang/lib/Sema/SemaDecl.cpp | 84 +++++-------------- clang/lib/Sema/SemaDeclCXX.cpp | 11 +++ clang/lib/Sema/SemaTemplateInstantiateDecl.cpp | 110 ++++++++++++------------- clang/test/SemaTemplate/friend.cpp | 7 ++ 6 files changed, 159 insertions(+), 128 deletions(-) https://bugs.llvm.org/show_bug.cgi?id=42513 https://bugs.llvm.org/show_bug.cgi?id=42513
