Dehao Chen a75059ebaa Encode duplication factor from loop vectorization and loop unrolling to discriminator. ... Summary: This patch starts the implementation as discuss in the following RFC: http://lists.llvm.org/pipermail/llvm-dev/2016-October/106532.html When optimization duplicates code that will scale down the execution count of a basic block, we will record the duplication factor as part of discriminator so that the offline process tool can find the duplication factor and collect the accurate execution frequency of the corresponding source code. Two important optimization that fall into this category is loop vectorization and loop unroll. This patch records the duplication factor for these 2 optimizations. The recording will be guarded by a flag encode-duplication-in-discriminators, which is off by default.
