* detabify llvm, patch by Mike Stump!Chris Lattner2008-03-201-36/+36
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48577 91177308-0d34-0410-b5e6-96231b3b80d8
* Miscellaneous clean-ups based on Evan's feedback:Bill Wendling2008-03-031-42/+52
| | | | | | | | | | | - Cleaned up how the prologue-epilogue inserter loops over the instructions. - Instead of restarting the processing of an instruction if we remove an implicit kill, just update the end iterator and make sure that the iterator isn't incremented. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47870 91177308-0d34-0410-b5e6-96231b3b80d8

* Rename MRegisterInfo to TargetRegisterInfo.Dan Gohman2008-02-101-11/+11

* SDIsel processes llvm.dbg.declare by recording the variable debug ↵Evan Cheng2008-02-021-2/+5
| | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46659 91177308-0d34-0410-b5e6-96231b3b80d8
* Remove the nasty LABEL hack with a much less evil one. Now ↵Evan Cheng2008-02-011-7/+0
| | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46635 91177308-0d34-0410-b5e6-96231b3b80d8
* Add an extra operand to LABEL nodes which distinguishes between debug, EH, ↵Evan Cheng2008-01-311-1/+1
| | | | | | or misc labels. This fixes the EH breakage. However I am not convinced this is *the* solution. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46609 91177308-0d34-0410-b5e6-96231b3b80d8
* Also avoid adding callee save code before debug labels.Evan Cheng2008-01-311-1/+9

* rename TargetInstrDescriptor -> TargetInstrDesc.Chris Lattner2008-01-071-3/+3
| | | | | | | | Make MachineInstr::getDesc return a reference instead of a pointer, since it can never be null. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45695 91177308-0d34-0410-b5e6-96231b3b80d8
* Move a bunch more accessors from TargetInstrInfo to TargetInstrDescriptorChris Lattner2008-01-071-3/+2
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45680 91177308-0d34-0410-b5e6-96231b3b80d8
* Rename MachineInstr::getInstrDescriptor -> getDesc(), which reflectsChris Lattner2008-01-071-1/+1
| | | | | | | | | | | | | | | | | | 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

* Rename SSARegMap -> MachineRegisterInfo in keeping with the idea Chris Lattner2007-12-311-4/+5
| | | | | | | | | | | | | | | | that "machine" classes are used to represent the current state of the code being compiled. Given this expanded name, we can start moving other stuff into it. For now, move the UsedPhysRegs and LiveIn/LoveOuts vectors from MachineFunction into it. Update all the clients to match. This also reduces some needless #includes, such as MachineModuleInfo from MachineFunction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45467 91177308-0d34-0410-b5e6-96231b3b80d8
