From 6de0b449c07ec7adbcb34e7c94c544ee37ef5963 Mon Sep 17 00:00:00 2001 From: Nicolas Lesser Date: Sat, 4 May 2019 00:09:00 +0000 Subject: [clang] adding explicit(bool) from c++2a this patch adds support for the explicit bool specifier. Changes: - The parsing for the explicit(bool) specifier was added in ParseDecl.cpp. - The storage of the explicit specifier was changed. the explicit specifier was stored as a boolean value in the FunctionDeclBitfields and in the DeclSpec class. now it is stored as a PointerIntPair with a flag and a potential expression in CXXConstructorDecl, CXXDeductionGuideDecl, CXXConversionDecl and in the DeclSpec class. - Following the AST change, Serialization, ASTMatchers, ASTComparator and ASTPrinter were adapted. - Template instantiation was adapted to instantiate the potential expressions of the explicit(bool) specifier When instantiating their associated declaration. - The Add*Candidate functions were adapted, they now take a Boolean indicating if the context allowing explicit constructor or conversion function and this boolean is used to remove invalid overloads that required template instantiation to be detected. - Test for Semantic and Serialization were added. This patch is not yet complete. I still need to check that interaction with CTAD and deduction guides is correct. and add more tests for AST operations. But I wanted first feedback. Perhaps this patch should be spited in smaller patches, but making each patch testable as a standalone may be tricky.
