Wei Mi 6e3344ed98 Limiting gep merging to fix the performance problem described in ... https://llvm.org/bugs/show_bug.cgi?id=23163. Gep merging sometimes behaves like a reverse CSE/LICM optimizations, which has negative impact on performance. In this patch we restrict gep merging to happen only when the indexes to be merged are both consts, which ensures such merge is always beneficial. The patch makes gep merging only happen in very restrictive cases. It is possible that some analysis/optimization passes rely on the merged geps to get better result, and we havn't notice them yet. We will be ready to further improve it once we see the cases. Differential Revision: http://reviews.llvm.org/D9007 llvm-svn: 235451		2015-04-21 22:37:09 +00:00
