* Add a little heuristic to Value::isUsedInBasicBlock to speed it up for small ↵Benjamin Kramer2011-12-051-8/+1
| | | | | | | | | | basic blocks. - Calling getUser in a loop is much more expensive than iterating over a few instructions. - Use it instead of the open-coded loop in AddrModeMatcher. - 5% speedup on ARMDisassembler.cpp Release builds. llvm-svn: 145810

* Revert 101465, it broke internal OpenGL testing.Eric Christopher2010-04-161-2/+2

* Teach SCEVExpander to expand arithmetic involving pointers into GEPDan Gohman2009-05-191-30/+31
| | | | | | | | | | | | | | | | 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. llvm-svn: 72093
