2004-06-29Do not dereference end iterators. It hurts when you do that.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14474 91177308-0d34-0410-b5e6-96231b3b80d8
2004-06-27Do not find these ugly sparc-specific objects by using the annotation API onChris Lattner
instructions. Instead, keep a map of instructions -> MCFI objects in the already sparc-specific class MachineFunctionInfo. This will slow down the sparc backend a bit, but it does not penalize the rest of LLVM! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14438 91177308-0d34-0410-b5e6-96231b3b80d8
2004-06-25Made a fix so that you can print out MachineInstrs that belong to a ↵Tanya Lattner
MachineBasicBlock that is not yet attached to a MachineFunction. This change includes changing the third operand (TargetMachine) to a pointer for the MachineInstr::print function. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14389 91177308-0d34-0410-b5e6-96231b3b80d8

2004-06-22Making an archive version of the CodeGen library is unnecessary if we justMisha Brukman
move InstructionLowering itself. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14324 91177308-0d34-0410-b5e6-96231b3b80d8
2004-06-22Provide archive version of CodeGen library (for those tools that only needMisha Brukman
IntrinsicLowering, for instance). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14323 91177308-0d34-0410-b5e6-96231b3b80d8
2004-06-21Rename Interval class to LiveInterval to avoid conflicting with the alreadyChris Lattner
existing llvm::Interval class. Patch contributed by Vladimir Prus! http://mail.cs.uiuc.edu/pipermail/llvmbugs/2004-June/000710.html git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14281 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14201 91177308-0d34-0410-b5e6-96231b3b80d8
2004-06-16Fix a recent regression in Applications/sgefa that Alkis pointed out to me.Chris Lattner
The vector may actually be empty if the register that we are marking as recently used is not actually allocatable. This happens for physical registers that are not allocatable, like the ST(x) registers on X86. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14195 91177308-0d34-0410-b5e6-96231b3b80d8

2004-06-11Fix fallout from getOffsetOfLocalArea() being negated. Debugging dumps were ↵Chris Lattner
being printed incorrectly, and we were reserving 8 extra bytes of stack space for functions on X86. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14152 91177308-0d34-0410-b5e6-96231b3b80d8

targets whose stack grows up. Patch contributed by Vladimir Prus git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14111 91177308-0d34-0410-b5e6-96231b3b80d8
2004-06-05Remove an unused variable.Chris Lattner
Work around for bogus errors: no those static functions don't need to be executed to be initialized! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14040 91177308-0d34-0410-b5e6-96231b3b80d8

2004-05-30When spilling an register, introduce a new temporary for each of itsAlkis Evlogimenos
spills. This allows for more flexibility when allocating registers for spill code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13907 91177308-0d34-0410-b5e6-96231b3b80d8

2004-05-26Updating my cvs versions. THis is still in progress and much will be changed.Tanya Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13782 91177308-0d34-0410-b5e6-96231b3b80d8
2004-05-24Moved MachineBasicBlock deconstructor to cpp file and removed it from ↵Tanya Lattner
LeakDetector to fix memory leak bug. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13718 91177308-0d34-0410-b5e6-96231b3b80d8
2004-05-24Added MachineFunction parent* to MachineBasicBlock. Customized ilist templateTanya Lattner
to set the parent when a MachineBasicBlock is added to a MachineFunction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13716 91177308-0d34-0410-b5e6-96231b3b80d8
2004-05-24Eliminate an explicit use of the LLVM basic block, using getParent instead,Chris Lattner
which simplifies the code git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13707 91177308-0d34-0410-b5e6-96231b3b80d8
2004-05-24Changed clone to be const.Tanya Lattner
Changed copy constructor to set parent, prev, and next pointers to null. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13706 91177308-0d34-0410-b5e6-96231b3b80d8
2004-05-23Fixed up my changes to add support for cloning Machine Instructions.Tanya Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13665 91177308-0d34-0410-b5e6-96231b3b80d8
2004-05-23Adding support to clone MachineInstrTanya Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13661 91177308-0d34-0410-b5e6-96231b3b80d8
2004-05-12Fix a really nasty bug from my changes on Monday to PHIElim. These changesChris Lattner
broke obsequi and a lot of other things. It all boiled down to MBB being overloaded in an inner scope and me confusing it with the one in the outer scope. Ugh! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13517 91177308-0d34-0410-b5e6-96231b3b80d8
2004-05-12Start NextMBBNumber out at zero.Brian Gaeke
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13515 91177308-0d34-0410-b5e6-96231b3b80d8
2004-05-12Add non-const MachineBasicBlock::getParent() accessor method.Brian Gaeke
MBBs start out as #-1. When a MBB is added to a MachineFunction, it gets the next available unique MBB number. If it is removed from a MachineFunction, it goes back to being #-1. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13514 91177308-0d34-0410-b5e6-96231b3b80d8
2004-05-10Switch this from using an std::map to using a DenseMap. This speeds upChris Lattner
phi-elimination from 0.6 to 0.54s on kc++. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13454 91177308-0d34-0410-b5e6-96231b3b80d8
2004-05-10Use a new VRegPHIUseCount to compute uses of PHI values by other phi valuesChris Lattner
in the basic block being processed. This fixes PhiElimination on kimwitu++ from taking 105s to taking a much more reasonable 0.6s (in a debug build). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13453 91177308-0d34-0410-b5e6-96231b3b80d8
2004-05-10Now that we use an ilist of machine instructions, iterators are more robustChris Lattner
than before. Because this is the case, we can compute the first non-phi instruction once when de-phi'ing a block. This shaves ~4s off of phielimination of _Z7yyparsev in kimwitu++ from 109s -> 105s. There are still much more important gains to come. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13452 91177308-0d34-0410-b5e6-96231b3b80d8
2004-05-10Patch to fix PR337. Make sure to mark all aliased physical registers as usedChris Lattner
when we see a read of a register. This is important in cases like: AL = ... AH = ... = AX The read of AX must make both the AL and AH defs live until the use. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13444 91177308-0d34-0410-b5e6-96231b3b80d8
