Pre-instrumentation inline (pre-inliner) greatly improves the IR instrumentation code performance, among other benefits. One issue of the pre-inliner is it can introduce CFG-mismatch for COMDAT functions. This is due to the fact that the same COMDAT function may have different early inline decisions across different modules -- that means different copies of COMDAT functions will have different CFG checksum. In this patch, we propose a partially renaming the COMDAT group and its member function/variable so we have different profile counter for each version. We will post-fix the COMDAT function and the group name with its FunctionHash. Differential Revision: http://reviews.llvm.org/D22600 llvm-svn: 276673
