2010-04-07Generalize IVUsers to track arbitrary expressions rather than expressionsDan Gohman
explicitly split into stride-and-offset pairs. Also, add the ability to track multiple post-increment loops on the same expression. This refines the concept of "normalizing" SCEV expressions used for to post-increment uses, and introduces a dedicated utility routine for normalizing and denormalizing expressions. This fixes the expansion of expressions which are post-increment users of more than one loop at a time. More broadly, this takes LSR another step closer to being able to reason about more than one loop at a time. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100699 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-07Fixed a bug where the disassembler would allow an immediateSean Callanan
argument that had to be between 0 and 7 to have any value, firing an assert later in the AsmPrinter. Now, the disassembler rejects instructions with out-of-range values for that immediate. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100694 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-07VHADD differs from VHSUB at least on A9 - the former reads both operands in ↵Anton Korobeynikov
