This caused PR32977. Original commit message: > Make it illegal for two Functions to point to the same DISubprogram > > As recently discussed on llvm-dev [1], this patch makes it illegal for > two Functions to point to the same DISubprogram and updates > FunctionCloner to also clone the debug info of a function to conform > to the new requirement. To simplify the implementation it also factors > out the creation of inlineAt locations from the Inliner into a > general-purpose utility in DILocation. > > [1] http://lists.llvm.org/pipermail/llvm-dev/2017-May/112661.html > <rdar://problem/31926379> > > Differential Revision: https://reviews.llvm.org/D32975 llvm-svn: 302533
