2012-12-10Merging r169719: into 3.2 release branch.Pawel Wodnicki
Fix PR14548: SROA was crashing on a mixture of i1 and i8 loads and stores. When SROA was evaluating a mixture of i1 and i8 loads and stores, in just a particular case, it would tickle a latent bug where we compared bits to bytes rather than bits to bits. As a consequence of the latent bug, we would allow integers through which were not byte-size multiples, a situation the later rewriting code was never intended to handle. In release builds this could trigger all manner of oddities, but the reported issue in PR14548 was forming invalid bitcast instructions. The only downside of this fix is that it makes it more clear that SROA in its current form is not capable of handling mixed i1 and i8 loads and stores. Sometimes with the previous code this would work by luck, but usually it would crash, so I'm not terribly worried. I'll watch the LNT numbers just to be sure. git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_32@169735 91177308-0d34-0410-b5e6-96231b3b80d8

Fix PR14060, an infinite loop in reassociate. The problem was that one of the operands of the expression being written was wrongly thought to be reusable as an inner node of the expression resulting in it turning up as both an inner node *and* a leaf, creating a cycle in the def-use graph. This would have caused the verifier to blow up if things had gotten that far, however it managed to provoke an infinite loop first. git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_32@168489 91177308-0d34-0410-b5e6-96231b3b80d8

Fix PR14361: wrong simplification of A+B==B+A. You may think that the old logic replaced by this patch is equivalent to the new logic, but you'd be wrong, and that's exactly where the bug was. There's a similar bug in instsimplify which manifests itself as instsimplify failing to simplify this, rather than doing it wrong, see next commit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_32@168447 91177308-0d34-0410-b5e6-96231b3b80d8
2012-11-21Merging r168035: into 3.2 release branch.Pawel Wodnicki
Fix a crash observed by Shuxin Yang. The issue here is that LinearizeExprTree, the utility for extracting a chain of operations from the IR, thought that it might as well combine any constants it came across (rather than just returning them along with everything else). On the other hand, the factorization code would like to see the individual constants (this is quite reasonable: it is much easier to pull a factor of 3 out of 2*3 than it is to pull it out of 6; you may think 6/3 isn't so hard, but due to overflow it's not as easy to undo multiplications of constants as it may at first appear). This patch therefore makes LinearizeExprTree stupider: it now leaves optimizing to the optimization part of reassociate, and sticks to just analysing the IR. git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_32@168446 91177308-0d34-0410-b5e6-96231b3b80d8
2012-11-21Merging r168361, r168346 and r168227 into 3.2 branch releasePawel Wodnicki
Merging r168361: Fix PR14132 and handle OOB loads speculated throuh PHI nodes. The issue is that we may end up with newly OOB loads when speculating a load into the predecessors of a PHI node, and this confuses the new integer splitting logic in some cases, triggering an assertion failure. In fact, the branch in question must be dead code as it loads from a too-narrow alloca. Add code to handle this gracefully and leave the requisite FIXMEs for both optimizing more aggressively and doing more to aid sanitizing invalid code which triggers these patterns. Merging r168346: ------------------------------------------------------------------------ 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.
