Chandler Carruth aa3cb334af Teach the integer-promotion rewrite strategy to be endianness aware. ... Sorry for this being broken so long. =/ As part of this, switch all of the existing tests to be Little Endian, which is the behavior I was asserting in them anyways! Add in a new big-endian test that checks the interesting behavior there. Another part of this is to tighten the rules abotu when we perform the full-integer promotion. This logic now rejects cases where there fully promoted integer is a non-multiple-of-8 bitwidth or cases where the loads or stores touch bits which are in the allocated space of the alloca but are not loaded or stored when accessing the integer. Sadly, these aren't really observable today as the rest of the pass will already ensure the invariants hold. However, the latter situation is likely to become a potential concern in the future. Thanks to Benjamin and Duncan for early review of this patch. I'm still looking into whether there are further endianness issues, please let me know if anyone sees BE failures persisting past this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165219 91177308-0d34-0410-b5e6-96231b3b80d8		2012-10-04 10:39:28 +00:00
