We previously didnot instantiate exception specifications of functions if they were only used inunevaluated contexts (other than 'noexcept' expressions).In C++17 onwards, this becomes essential since the exception specification isnow part of the function's type.Note that this means that constructs like the following no longer work: struct A { static T f() noexcept(...); decltype(f()) *p; };... because the decltype expression now needs the exception specification of'f', which has not yet been parsed.llvm-svn: 284549 List of files: /llvm-project-15.0.7/clang/test/SemaCXX/libstdcxx_pair_swap_hack.cpp Tue, 18 Oct 2016 23:39:12 +0000 Richard Smith <richard-llvm@metafoo.co.uk> http://172.16.0.5:8080/history/llvm-project-15.0.7/clang/test/SemaCXX/libstdcxx_pair_swap_hack.cpp#8643639a PR28423: Compare primary declaration contexts.In certain cases (mostly coming from modules), Sema's idea of the StdNamespacedoes not point to the first declaration of namespace std.Patch by Cristina Cristescu!Reviewed by Richard Smith.llvm-svn: 279371 List of files: /llvm-project-15.0.7/clang/test/SemaCXX/libstdcxx_pair_swap_hack.cpp Sat, 20 Aug 2016 14:50:22 +0000 Vassil Vassilev <v.g.vassilev@gmail.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/clang/test/SemaCXX/libstdcxx_pair_swap_hack.cpp#3ef3e899 PR21565: Further refine the conditions for enabling eager parsing ofstd::X::swap exception specifications (allowing parsing of non-conforming codein libstdc++).

With delay-parsed exception specifications, thecall to 'swap' unambiguously finds the function being declared, which thenfails because the arguments don't work for that function.llvm-svn: 221955 List of files: /llvm-project-15.0.7/clang/test/SemaCXX/libstdcxx_pair_swap_hack.cpp Fri, 14 Nov 2014 00:37:55 +0000 Richard Smith <richard-llvm@metafoo.co.uk>
