* Sink store based on alias analysisElena Demikhovsky2014-12-151-40/+35
| | | | | | | | | | | | - by Ella Bolshinsky The alias analysis is used define whether the given instruction is a barrier for store sinking. For 2 identical stores, following instructions are checked in the both basic blocks, to determine whether they are sinking barriers. http://reviews.llvm.org/D6420 llvm-svn: 224247

Merges equivalent loads on both sides of a hammock/diamond and hoists into into the header. Merges equivalent stores on both sides of a hammock/diamond and sinks it to the footer. Can enable if conversion and tolerate better load misses and store operand latencies. llvm-svn: 213396
