2011-02-12AsmMatcher custom operand parser failure enhancements.Jim Grosbach
Teach the AsmMatcher handling to distinguish between an error custom-parsing an operand and a failure to match. The former should propogate the error upwards, while the latter should continue attempting to parse with alternative matchers. Update the ARM asm parser accordingly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125426 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-11Per discussion with Dan G, inbounds geps *certainly* can haveChris Lattner
unsigned overflow (e.g. "gep P, -1"), and while they can have signed wrap in theoretical situations, modelling an AddRec as not having signed wrap is going enough for any case we can think of today. In the future if this isn't enough, we can revisit this. Modeling them as having NUW isn't causing any known problems either FWIW. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125410 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-11When lowering an inbounds gep, the intermediate adds can haveChris Lattner
unsigned overflow (e.g. due to a negative array index), but the scales on array size multiplications are known to not sign wrap. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125409 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-11Fix #9190Nadav Rotem
The bug happens when the DAGCombiner attempts to optimize one of the patterns of the SUB opcode. It tries to create a zero of type v2i64. This type is legal on 32bit machines, but the initializer of this vector (i64) is target dependent. Currently, the initializer attempts to create an i64 zero constant, which fails. Added a flag to tell the DAGCombiner to create a legal zero, if we require that the pass would generate legal types. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125391 91177308-0d34-0410-b5e6-96231b3b80d8
