This new pass removes unnecessary accesses and writes. It currently supports 2 simplifications, but more are planned. It removes write accesses that write a loaded value back to the location it was loaded from. It is a typical artifact from DeLICM. Removing it will get rid of bogus dependencies later in dependency analysis. It also removes statements without side-effects. ScopInfo already removes these, but the removal of unnecessary writes can result in more side-effect free statements. Differential Revision: https://reviews.llvm.org/D30820 llvm-svn: 297473 |
