2008-01-11More CellSPU refinement and progress:Scott Michel
- Cleaned up custom load/store logic, common code is now shared [see note below], cleaned up address modes - More test cases: various intrinsics, structure element access (load/store test), updated target data strings, indirect function calls. Note: This patch contains a refactoring of the LoadSDNode and StoreSDNode structures: they now share a common base class, LSBaseSDNode, that provides an interface to their common functionality. There is some hackery to access the proper operand depending on the derived class; otherwise, to do a proper job would require finding and rearranging the SDOperands sent to StoreSDNode's constructor. The current refactor errs on the side of being conservatively and backwardly compatible while providing functionality that reduces redundant code for targets where loads and stores are custom-lowered. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45851 91177308-0d34-0410-b5e6-96231b3b80d8

Cosmetic changes to spacing to match gcc (some dejagnu tests actually care). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45848 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-10Simplify the side effect stuff a bit more and make licm/sinkingChris Lattner
both work right according to the new flags. This removes the TII::isReallySideEffectFree predicate, and adds TII::isInvariantLoad. It removes NeverHasSideEffects+MayHaveSideEffects and adds UnmodeledSideEffects as machine instr flags. Now the clients can decide everything they need. I think isRematerializable can be implemented in terms of the flags we have now, though I will let others tackle that. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45843 91177308-0d34-0410-b5e6-96231b3b80d8

Likewise fix up a bunch of other libcalls. While there I remove NEG_F32 and NEG_F64 since they are not used anywhere. This fixes 9 Ada ACATS failures. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45833 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-10Start inferring side effect information more aggressively, and fix many bugs ↵Chris Lattner
in the x86 backend where instructions were not marked maystore/mayload, and perf issues where instructions were not marked neverHasSideEffects. It would be really nice if we could write patterns for copy instructions. I have audited all the x86 instructions down to MOVDQAmr. The flags on others and on other targets are probably not right in all cases, but no clients currently use this info that are enabled by default. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45829 91177308-0d34-0410-b5e6-96231b3b80d8

2008-01-07Add predicates methods to TargetOperandInfo, and switch all clients Chris Lattner
over to using them, instead of diddling Flags directly. Change the various flags from const variables to enums. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45677 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-07Rename MachineInstr::getInstrDescriptor -> getDesc(), which reflectsChris Lattner
that it is cheap and efficient to get. Move a variety of predicates from TargetInstrInfo into TargetInstrDescriptor, which makes it much easier to query a predicate when you don't have TII around. Now you can use MI->getDesc()->isBranch() instead of going through TII, and this is much more efficient anyway. Not all of the predicates have been moved over yet. Update old code that used MI->getInstrDescriptor()->Flags to use the new predicates in many places. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45674 91177308-0d34-0410-b5e6-96231b3b80d8
