New Revision: 338083
URL: http://llvm.org/viewvc/llvm-project?rev=338083&view=rev
Log:
[MS] Add L__FUNCSIG__ for compatibility
Clang already has L__FUNCTION__ as a workaround for dealing with
pre-processor code that expects to be able to do L##__FUNCTION__ in a
macro. This patch implements the same logic for __FUNCSIG__.
Fixes PR38295.
