Duncan P. N. Exon Smith f5d17528ee Module: Don't rename in getOrInsertFunction() ... During LTO, user-supplied definitions of C library functions often exist. -instcombine uses Module::getOrInsertFunction() to get a handle on library functions (e.g., @puts, when optimizing @printf). Previously, Module::getOrInsertFunction() would rename any matching functions with local linkage, and create a new declaration. In LTO, this is the opposite of desired behaviour, as it skips by the user-supplied version of the library function and creates a new undefined reference which the linker often cannot resolve. After some discussing with Rafael on the list, it looks like it's undesired behaviour. If a consumer actually *needs* this behaviour, we should add new API with a more explicit name. I added two testcases: one specifically for the -instcombine behaviour and one for the LTO flow. <rdar://problem/16165191> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@203513 91177308-0d34-0410-b5e6-96231b3b80d8		2014-03-10 23:42:28 +00:00
