Chandler Carruth 50bc165c54 [SROA] Fix PR18615 with some long overdue simplifications to the bounds ... checking in SROA. The primary change is to just rely on uge for checking that the offset is within the allocation size. This removes the explicit checks against isNegative which were terribly error prone (including the reversed logic that led to PR18615) and prevented us from supporting stack allocations larger than half the address space.... Ok, so maybe the latter isn't *common* but it's a silly restriction to have. Also, we used to try to support a PHI node which loaded from before the start of the allocation if any of the loaded bytes were within the allocation. This doesn't make any sense, we have never really supported loading or storing *before* the allocation starts. The simplified logic just doesn't care. We continue to allow loading past the end of the allocation in part to support cases where there is a PHI and some loads are larger than others and the larger ones reach past the end of the allocation. We could solve this a different and more conservative way, but I'm still somewhat paranoid about this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@202224 91177308-0d34-0410-b5e6-96231b3b80d8		2014-02-26 03:14:14 +00:00
