* From Chris' review: use cast instead of dyn_cast with an assert.Dan Gohman2008-02-111-8/+4

* Added "Profile" method to APFloat for use with FoldingSet.Ted Kremenek2008-02-111-3/+3
| | | | | | | | | | Added member template "Add" to FoldingSetNodeID that allows "adding" arbitrary objects to a profile via dispatch to FoldingSetTrait<T>::Profile(). Removed FoldingSetNodeID::AddAPFloat and FoldingSetNodeID::APInt, as their functionality is now replaced using the above mentioned member template. llvm-svn: 46957

* Dwarf requires variable entries to be in the source order. Right now, since ↵Evan Cheng2008-02-041-4/+7
| | | | | | we are recording variable information at isel time this means parameters would appear in the reverse order. The short term fix is to issue recordVariable() at asm printing time instead. llvm-svn: 46724
* I don't see how NodeUpdated can be called with aDuncan Sands2008-02-041-5/+10
| | | | | | | | | | | | | | | | | | | | ReadyToProcess node - add an assertion to check this. Add an assertion to NodeDeleted that checks that processed/ready nodes are indeed not deleted. It is because they are never deleted that none of the maps can have a deleted node as the source of a mapping. It does however seem to be possible in theory to have a deleted value as the target of a mapping, however this has not yet been spotted in the wild. Still mulling on what to do about this. [The theoretical situation is this: a node A is expanded/promoted/whatever to a newly created node B. Thus A->B is added to a map. When the subtree rooted at B is legalized it is conceivable that B is deleted due to RAUW on a node somewhere above it]. llvm-svn: 46705

* Use the new infrastructure for listening to node updates to Chris Lattner2008-02-032-31/+34
| | | | | | | | keep the LegalizeTypes node flags up to date when doing a RAUW. This fixes a nasty bug that Duncan ran into and makes the previous (nonbuggy case) more efficent. llvm-svn: 46679
* the world doesn't need my debugging code.Chris Lattner2008-02-031-1/+0
| | | | llvm-svn: 46678
* Change the 'global modification' APIs in SelectionDAG to take a newChris Lattner2008-02-032-162/+209
| | | | | | | | | | DAGUpdateListener object pointer instead of just returning a vector of deleted nodes. This makes the interfaces more efficient (no more allocating a vector [at least a malloc], filling it in, then walking it) and more clean. This also allows the client to be notified of nodes that are *changed* but not deleted. llvm-svn: 46677
* Generalize the SDOperand->SDOperand form of Chris Lattner2008-02-031-17/+16
| | | | | | | | | SelectionDAG::ReplaceAllUsesWith to handle replacement of an SDOperand with *any* sdoperand, not just one for a node with a single result. Note that this has a horrible FIXME'd hack in it to work around PR1975. This should be removed when PR1975 is fixed. llvm-svn: 46674

* Get rid of the annoying blank lines before labels.Evan Cheng2008-02-021-3/+3
| | | | llvm-svn: 46667
* SDIsel processes llvm.dbg.declare by recording the variable debug ↵Evan Cheng2008-02-027-16/+51
| | | | | | | | | information descriptor and its corresponding stack frame index in MachineModuleInfo. This only works if the local variable is "homed" in the stack frame. It does not work for byval parameter, etc. Added ISD::DECLARE node type to represent llvm.dbg.declare intrinsic. Now the intrinsic calls are lowered into a SDNode and lives on through out the codegen passes. For now, since all the debugging information recording is done at isel time, when a ISD::DECLARE node is selected, it has the side effect of also recording the variable. This is a short term solution that should be fixed in time. llvm-svn: 46659
* Remove the nasty LABEL hack with a much less evil one. Now ↵Evan Cheng2008-02-015-35/+24
| | | | | | llvm.dbg.func.start implies a stoppoint is set. SelectionDAGISel records a new source line but does not create a ISD::LABEL node for this special stoppoint. Asm printer will magically print this label. This ensures nothing is emitted before. llvm-svn: 46635
* Rename RecordLabel to RecordSourceLine because that's what it is doing.Evan Cheng2008-02-012-4/+4

| | | | llvm-svn: 46610
* Add an extra operand to LABEL nodes which distinguishes between debug, EH, ↵Evan Cheng2008-01-318-22/+51
| | | | | | or misc labels. This fixes the EH breakage. However I am not convinced this is *the* solution. llvm-svn: 46609
* Add more thorough error checking for NULL register classes.Christopher Lamb2008-01-311-1/+2
| | | | llvm-svn: 46605
* MRegisterInfo::getLocation() is a really bad idea. Its function is to ↵Evan Cheng2008-01-311-1/+2
| | | | | | | | calculate the offset from frame pointer to a stack slot and then storing the delta in a MachineLocation object. The name is bad (it implies a getter), and MRegisterInfo doesn't need to know about MachineLocation. Replace getLocation() with getFrameIndexOffset() which returns the delta from frame pointer to stack slot. Dwarf writer can then use the information for whatever it wants. llvm-svn: 46597
* Rename ISD::FLT_ROUNDS to ISD::FLT_ROUNDS_ to avoid conflictingDan Gohman2008-01-313-3/+3
| | | | | | with the real FLT_ROUNDS (defined in <float.h>). llvm-svn: 46587
* Also avoid adding callee save code before debug labels.Evan Cheng2008-01-311-1/+9
| | | | llvm-svn: 46586
* Create a new class, MemOperand, for describing memory referencesDan Gohman2008-01-315-48/+190
| | | | | | | | | | | | | | | | in the backend. Introduce a new SDNode type, MemOperandSDNode, for holding a MemOperand in the SelectionDAG IR, and add a MemOperand list to MachineInstr, and code to manage them. Remove the offset field from SrcValueSDNode; uses of SrcValueSDNode that were using it are all all using MemOperandSDNode now. Also, begin updating some getLoad and getStore calls to use the PseudoSourceValue objects. Most of this was written by Florian Brander, some reorganization and updating to TOT by me. llvm-svn: 46585

| | | | | | | | | | dbg_func_start label. Make sure nothing else is inserted before them. Note this solution might be somewhat fragile since ISD::LABEL may be used for other purposes. If that ends up to be an issue, we may need to introduce a different node for debug labels. llvm-svn: 46571
