* SDIsel processes llvm.dbg.declare by recording the variable debug ↵Evan Cheng2008-02-0217-18/+72
| | | | | | | | | 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 Cheng2008-02-017-55/+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: 46628

* Chris' change to print an approximation to long doublesDale Johannesen2008-01-311-1/+2
| | | | | | | exposed a bug in APFloat's long double->double conversion of NaNs. Broke several things in the ieee part of gcc testsuite. llvm-svn: 46617
* Add a comment for a nasty short term hack.Evan Cheng2008-01-311-0/+4

* Add an extra operand to LABEL nodes which distinguishes between debug, EH, ↵Evan Cheng2008-01-3112-34/+63
| | | | | | or misc labels. This fixes the EH breakage. However I am not convinced this is *the* solution. llvm-svn: 46609
* Allow ComplexExpressions in InstrInfo.td files to be slightly more... ↵Christopher Lamb2008-01-311-1/+9
| | | | | | | | | | complex! ComplexExpressions can now have attributes which affect how TableGen interprets the pattern when generating matchin code. The first (and currently, only) attribute causes the immediate parent node of the ComplexPattern operand to be passed into the matching code rather than the node at the root of the entire DAG containing the pattern. llvm-svn: 46606
* Add more thorough error checking for NULL register classes.Christopher Lamb2008-01-311-1/+2
| | | | llvm-svn: 46605
* Add x86 specific getFrameIndexOffset(). This fixes local variable debugging ↵Evan Cheng2008-01-312-0/+15

* MRegisterInfo::getLocation() is a really bad idea. Its function is to ↵Evan Cheng2008-01-312-13/+8
| | | | | | | | 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
* Makes the same change in ppc backend: avoid inserting prologue before debug ↵Evan Cheng2008-01-311-0/+10

* Create a new class, MemOperand, for describing memory referencesDan Gohman2008-01-3111-142/+287
| | | | | | | | | | | | | | | | 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
* Fixed a bug in MergeValueInAsValue() pointed out by David Greene. Replace ↵Evan Cheng2008-01-301-3/+3
| | | | | | val# with previous liverange's. llvm-svn: 46579
* Treat the label for the first @llvm.dbg.stoppoint the same way as the ↵Evan Cheng2008-01-302-8/+12
| | | | | | | | | | 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
* Adjust loop per review feedback.Dale Johannesen2008-01-301-4/+2
| | | | llvm-svn: 46569

* Accept getelementptr starting at GV with all 0 indices as aDale Johannesen2008-01-301-0/+14
| | | | | | legitimate way of representing global variable GV in debug info. llvm-svn: 46565
* Even though InsertAtEndOfBasicBlock is an ugly hack it still deserves a ↵Evan Cheng2008-01-3012-35/+19
| | | | | | | | proper name. Rename it to EmitInstrWithCustomInserter since it does not necessarily insert instruction at the end. llvm-svn: 46562
* Add a new PseudoSourceValue class, which will be used to help trackDan Gohman2008-01-301-0/+33
| | | | | | | memory reference information in the backend. Most of this was written by Florian Brander, cleanup and updating to TOT by me. llvm-svn: 46556
* Remove a couple more cases of "getNumUses() == 0". No need to walk the linkedNick Lewycky2008-01-301-2/+2

| | | | llvm-svn: 46545
* More cleanups for CellSPU:Scott Michel2008-01-3018-3868/+4951
| | | | | | | | | - Expand tabs... (poss 80-col violations, will get them later...) - Consolidate logic for SelectDFormAddr and SelectDForm2Addr into a single function, simplifying maintenance. Also reduced custom instruction generation for SPUvecinsert/INSERT_MASK. llvm-svn: 46544
* Make DSE much more aggressive by performing DCE earlier. Update a testcase ↵Owen Anderson2008-01-301-2/+55
| | | | | | to reflect this increased aggressiveness. llvm-svn: 46542
* Fix an issue where, under very specific circumstances, memdep could end up ↵Owen Anderson2008-01-301-2/+2
| | | | | | | | dereferencing the end of one of its internal maps. llvm-svn: 46541
* Fix a bug where scalarrepl would discard offset if type would match.Chris Lattner2008-01-301-2/+2
| | | | | | | In practice this can only happen on code with already undefined behavior, but this is still a good thing to handle correctly. llvm-svn: 46539
* Factor the addressing mode and the load/store VT out of LoadSDNodeDan Gohman2008-01-3014-108/+108
| | | | | | | | and StoreSDNode into their common base class LSBaseSDNode. Member functions getLoadedVT and getStoredVT are replaced with the common getMemoryVT to simplify code that will handle both loads and stores. llvm-svn: 46538
* Work in progress. This patch *fixes* x86-64 calls which are modelled as ↵Evan Cheng2008-01-296-96/+283
| | | | | | | | StructRet but really should be return in registers, e.g. _Complex long double, some 128-bit aggregates. This is a short term solution that is necessary only because llvm, for now, cannot model i128 nor call's with multiple results. Status: This only works for direct calls, and only the caller side is done. Disabled for now. llvm-svn: 46527
* When expanding an operand, it's not the result valueDuncan Sands2008-01-291-2/+2
| | | | | | | | | | | type that matters but the operand type. This fixes 2008-01-08-IllegalCMP.ll which crashed with the new legalize infrastructure because SETCC with result type i8 and operand type i64 was being custom expanded by the X86 backend. With this fix, the gcc build gets as far as the first libcall. llvm-svn: 46525
