Small testcase.zip
I didn't compile lib/CodeGen/CGExprConstant.cpp with -fcxx-modules.
clang/lib/CodeGen/CGExprConstant.cpp:1041:16: error:
no matching function for call to 'cast'
return cast<ConstantAddress>(Res.getAddress());
^~~~~~~~~~~~~~~~~~~~~
llvm/include/llvm/Support/Casting.h:229:44: note:
candidate function [with X = clang::CodeGen::ConstantAddress, Y =
clang::CodeGen::Address] not viable: expects an l-value for 1st argument
inline typename cast_retty<X, Y>::ret_type cast(Y &Val) {
^
Seems namespace forwarders, Basic/LLVM.h, might not be effective there.
Appeased in r251713.
A small testcase is attached.
$ clang++ -std=c++11 -fmodules -fcxx-modules -c a.cc
