* Change the post-RA scheduler to iterate through theDan Gohman2009-02-031-9/+11
| | | | | | | | basic-block segments bottom-up instead of top down. This is the first step in a general restructuring of the way register liveness is tracked in the post-RA scheduler. llvm-svn: 63643
* First initialize DAG otherwise dwarf writer is used uninitialized.Devang Patel2009-02-032-2/+2
| | | | | | Duncan spotted this. Thanks! llvm-svn: 63641
* Fix PR3411. When replacing values, nodes are analyzedDuncan Sands2009-02-031-5/+7
| | | | | | | | | in any old order. Since analyzing a node analyzes its operands also, this can mean that when we pop a node off the list of nodes to be analyzed, it may already have been analyzed. llvm-svn: 63632
* Explicitly pass in debug location information to BuildMI.Bill Wendling2009-02-034-4/+6

* Pass in something sensible for the debug location information when creating theBill Wendling2009-02-033-6/+52

* Fill in some missing DL propagation in getNode()s.Dale Johannesen2009-02-031-22/+24
| | | | llvm-svn: 63595
* Use SDL->getCurDebugLoc() instead of unknown loc for landing pads.Bill Wendling2009-02-031-1/+1
| | | | llvm-svn: 63594
* Explicitly pass in the "unknown" debug location. This is probably notBill Wendling2009-02-032-2/+3
| | | | | | | correct. We need more infrastructure before we can get the DebugLoc info for these instructions. llvm-svn: 63593

* Propagate debug loc info during SDNode -> machine instr creation.Bill Wendling2009-02-031-6/+9
| | | | llvm-svn: 63585
* Create DebugLoc information in FastISel. Several temporary methods wereBill Wendling2009-02-033-29/+39
| | | | | | | created. Specifically, those BuildMIs which use "DebugLoc::getUnknownLoc()". I'll remove them soon. llvm-svn: 63584
* Propagation in TargetLowering. Includes passing a DLDale Johannesen2009-02-035-113/+132
| | | | | | into SimplifySetCC which gets called elsewhere. llvm-svn: 63583
* Use the SubclassData field to hold ExtType, isTrunc, and MemIndexedModeDan Gohman2009-02-031-45/+40
| | | | | | | | information. This eliminates the need for the Flags field in MemSDNode, so this makes LoadSDNode and StoreSDNode smaller. Also, it makes FoldingSetNodeIDs for loads and stores two AddIntegers smaller. llvm-svn: 63577
* Last DebugLoc propagation for this file.Dale Johannesen2009-02-021-180/+204

* MergeValueInto is too smart: it might choose to do the merge the opposite ↵Owen Anderson2009-02-022-3/+21

* Fix PR3453 and probably a bunch of other potentialDuncan Sands2009-02-013-22/+22
| | | | | | | | | crashes or wrong code with codegen of large integers: eliminate the legacy getIntegerVTBitMask and getIntegerVTSignBit methods, which returned their value as a uint64_t, so couldn't handle huge types. llvm-svn: 63494

* Fix PR3401: when using large integers, the typeDuncan Sands2009-01-318-101/+100
| | | | | | | | | | | | | returned by getShiftAmountTy may be too small to hold shift values (it is an i8 on x86-32). Before and during type legalization, use a large but legal type for shift amounts: getPointerTy; afterwards use getShiftAmountTy, fixing up any shift amounts with a big type during operation legalization. Thanks to Dan for writing the original patch (which I shamelessly pillaged). llvm-svn: 63482
