Author: mstorsjo Date: Thu Apr 4 10:50:14 2019 New Revision: 357711 URL: http://llvm.org/viewvc/llvm-project?rev=357711&view=rev Log: Move the alias definition of unw_getcontext to within !defined(__USING_SJLJ_EXCEPTIONS__)
For builds with SJLJ, there is no __unw_getcontext symbol. On Windows, the weak alias macro also expands to a dllexport directive, which fails if the symbol doesn't exist.
