2009-10-29Rename usesCustomDAGSchedInserter to usesCustomInserter, and update aDan Gohman
bunch of associated comments, because it doesn't have anything to do with DAGs or scheduling. This is another step in decoupling MachineInstr emitting from scheduling. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85517 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-18-Revert parts of 84326 and 84411. Distinquishing between fixed and non-fixedEvan Cheng
stack slots and giving them different PseudoSourceValue's did not fix the problem of post-alloc scheduling miscompiling llvm itself. - Apply Dan's conservative workaround by assuming any non fixed stack slots can alias other memory locations. This means a load from spill slot #1 cannot move above a store of spill slot #2. - Enable post-alloc scheduling for x86 at optimization leverl Default and above. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84424 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-14I don't see any point in having both eh.selector.i32 and eh.selector.i64,Duncan Sands
so get rid of eh.selector.i64 and rename eh.selector.i32 to eh.selector. Likewise for eh.typeid.for. This aligns us with gcc, which always uses a 32 bit value for the selector on all platforms. My understanding is that the register allocator used to assert if the selector intrinsic size didn't match the pointer size, and this was the reason for introducing the two variants. However my testing shows that this is no longer the case (I fixed some bugs in selector lowering yesterday, and some more today in the fastisel path; these might have caused the original problems). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84106 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-13Introduce new convenience methods for sign extending orDuncan Sands
truncating an SDValue (depending on whether the target type is bigger or smaller than the value's type); or zero extending or truncating it. Use it in a few places (this seems to be a popular operation, but I only modified cases of it in SelectionDAGBuild). In particular, the eh_selector lowering was doing this wrong due to a repeated rather than inverted test, fixed with this change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84027 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-10Create a new InstrEmitter class for translating SelectionDAG nodesDan Gohman
into MachineInstrs. This is mostly just moving the code from ScheduleDAGSDNodesEmit.cpp into a new class. This decouples MachineInstr emitting from scheduling. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@83699 91177308-0d34-0410-b5e6-96231b3b80d8
