* fix another bozo bugChris Lattner2009-08-181-2/+2
| | | | llvm-svn: 79313
* fix accidentally inverted conditional and add comment.Chris Lattner2009-08-181-1/+4
| | | | llvm-svn: 79312
* turn this conditional into something humans might actuallyChris Lattner2009-08-181-8/+25
| | | | | | be able to understand ;-) llvm-svn: 79311
* Re-apply LiveInterval index dumping patch, with fixes suggested by BillDavid Greene2009-08-031-4/+6
| | | | | | and others. llvm-svn: 78003
* Move more to raw_ostream, provide support for writing MachineBasicBlock,Daniel Dunbar2009-07-241-1/+11
| | | | | | LiveInterval, etc to raw_ostream. llvm-svn: 76965
* revert r76602, 76603, and r76615, pending design discussions.Chris Lattner2009-07-211-3/+1
| | | | llvm-svn: 76646
* Add PrefixPrinter arguments to the dump routines for MachineFunction andDavid Greene2009-07-211-1/+3
| | | | | | MachineBasicBlock. We'll use these shortly. llvm-svn: 76603
* If a MachineBasicBlock has multiple ways of reaching another block,Dan Gohman2009-05-051-4/+2
| | | | | | | | allow it to have multiple CFG edges to that block. This is needed to allow MachineBasicBlock::isOnlyReachableByFallthrough to work correctly. This fixes PR4126. llvm-svn: 71018
* Reapply 68073, with fixes. EH Landing-pad basic blocks are notDan Gohman2009-03-311-0/+10
| | | | | | | | entered via fall-through. Don't miss fallthroughs from blocks terminated by conditional branches. Also, move isOnlyReachableByFallthrough out of line. llvm-svn: 68129
* Constify arguments in isSuccessor and isLayoutSuccessor.Dan Gohman2009-03-301-2/+2
| | | | llvm-svn: 68054
* Delete unnecessary parens around return values.Dan Gohman2009-01-081-1/+1
| | | | llvm-svn: 61950
* Switch the MachineOperand accessors back to the short names likeDan Gohman2008-10-031-1/+1
| | | | | | isReg, etc., from isRegister, etc. llvm-svn: 57006
* Add a new MachineBasicBlock utility function, isLayoutSuccessor, thatDan Gohman2008-10-021-0/+5
| | | | | | | can be used when deciding if a block can transfer control to another via a fall-through instead of a branch. llvm-svn: 56968
* Remove isImm(), isReg(), and friends, in favor of Dan Gohman2008-09-131-1/+2
| | | | | | | | | isImmediate(), isRegister(), and friends, to avoid confusion about having two different names with the same meaning. I'm not attached to the longer names, and would be ok with changing to the shorter names if others prefer it. llvm-svn: 56189
* Fold the useful features of alist and alist_node into ilist, andDan Gohman2008-07-281-24/+12
| | | | | | | | | | | | | | | | a new ilist_node class, and remove them. Unlike alist_node, ilist_node doesn't attempt to manage storage itself, so it avoids the associated problems, including being opaque in gdb. Adjust the Recycler class so that it doesn't depend on alist_node. Also, change it to use explicit Size and Align parameters, allowing it to work when the largest-sized node doesn't have the greatest alignment requirement. Change MachineInstr's MachineMemOperand list from a pool-backed alist to a std::list for now. llvm-svn: 54146
* Re-introduce LeakDetector support for MachineInstrs and MachineBasicBlocks.Dan Gohman2008-07-171-0/+12
| | | | | | | Fix a leak that this turned up in LowerSubregs.cpp. And, comment a leak in LiveIntervalAnalysis.cpp. llvm-svn: 53746
* Pool-allocation for MachineInstrs, MachineBasicBlocks, andDan Gohman2008-07-071-53/+53
| | | | | | | | | | | MachineMemOperands. The pools are owned by MachineFunctions. This drastically reduces the number of calls to malloc/free made during the "Emit" phase of scheduling, as well as later phases in CodeGen. Combined with other changes, this speeds up the "instruction selection" phase of CodeGen by 10% in some cases. llvm-svn: 53212
* Added addition atomic instrinsics and, or, xor, min, and max.Mon P Wang2008-05-051-0/+13

| | | | | | 16-byte boundaries. llvm-svn: 47703
* Rename PrintableName to Name.Bill Wendling2008-02-261-1/+1
| | | | llvm-svn: 47629
* Change "Name" to "AsmName" in the target register info. Gee, a refactoring toolBill Wendling2008-02-261-1/+1
| | | | | | would have been a Godsend here! llvm-svn: 47625
* Rename MRegisterInfo to TargetRegisterInfo.Dan Gohman2008-02-101-7/+7
| | | | llvm-svn: 46930
* remove #includageChris Lattner2008-01-071-1/+1
| | | | llvm-svn: 45697
* 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. llvm-svn: 45695
* Rename MachineInstr::getInstrDescriptor -> getDesc(), which reflectsChris Lattner2008-01-071-4/+3
| | | | | | | | | | | | | | | 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. llvm-svn: 45674
* Implement automatically updated def/use lists for all MachineInstr register Chris Lattner2008-01-011-4/+55
| | | | | | | operands. The lists are currently kept in MachineRegisterInfo, but it does not yet provide an iterator interface to them. llvm-svn: 45477
* properly encapsulate the parent field of MBB and MI with get/set accessors.Chris Lattner2007-12-311-19/+21
| | | | llvm-svn: 45469
* Add new shorter predicates for testing machine operands for various types: Chris Lattner2007-12-301-3/+2
| | | | | | | | | | | | e.g. MO.isMBB() instead of MO.isMachineBasicBlock(). I don't plan on switching everything over, so new clients should just start using the shorter names. Remove old long accessors, switching everything over to use the short accessor: getMachineBasicBlock() -> getMBB(), getConstantPoolIndex() -> getIndex(), setMachineBasicBlock -> setMBB(), etc. llvm-svn: 45464
* Remove attribution from file headers, per discussion on llvmdev.Chris Lattner2007-12-291-2/+2
