Dan Gohman 5be18e8476 Teach SCEVExpander to expand arithmetic involving pointers into GEP ... instructions. It attempts to create high-level multi-operand GEPs, though in cases where this isn't possible it falls back to casting the pointer to i8* and emitting a GEP with that. Using GEP instructions instead of ptrtoint+arithmetic+inttoptr helps pointer analyses that don't use ScalarEvolution, such as BasicAliasAnalysis. Also, make the AddrModeMatcher more aggressive in handling GEPs. Previously it assumed that operand 0 of a GEP would require a register in almost all cases. It now does extra checking and can do more matching if operand 0 of the GEP is foldable. This fixes a problem that was exposed by SCEVExpander using GEPs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72093 91177308-0d34-0410-b5e6-96231b3b80d8		2009-05-19 02:15:55 +00:00
