Chandler Carruth f5837aacd4 Rework the rewriting of loads and stores for vector and integer allocas ... to properly handle the combinations of these with split integer loads and stores. This essentially replaces Evan's r168227 by refactoring the code in a different way, and trynig to mirror that refactoring in both the load and store sides of the rewriting. Generally speaking there was some really problematic duplicated code here that led to poorly founded assumptions and then subtle bugs. Now much of the code actually flows through and follows a more consistent style and logical path. There is still a tiny bit of duplication on the store side of things, but it is much less bad. This also changes the logic to never re-use a load or store instruction as that was simply too error prone in practice. I've added a few tests (one a reduction of the one in Evan's original patch, which happened to be the same as the report in PR14349). I'm going to look at adding a few more tests for things I found and fixed in passing (such as the volatile tests in the vectorizable predicate). This patch has survived bootstrap, and modulo one bugfix survived Duncan's test suite, but let me know if anything else explodes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168346 91177308-0d34-0410-b5e6-96231b3b80d8		2012-11-20 01:12:50 +00:00
