git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46930 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-08It's not always safe to fold movsd into xorpd, etc. Check the alignment of ↵Evan Cheng
the load address first to make sure it's 16 byte aligned. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46893 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-15Remove DefInst from LiveVariables::VarInfo. Use the facilities on ↵Owen Anderson
MachineRegisterInfo instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46016 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-11rename MachineInstr::setInstrDescriptor -> setDescChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45871 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-07Only mark instructions that load a single value without extension as ↵Evan Cheng
isSimpleLoad = 1. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45727 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-07rename TargetInstrDescriptor -> TargetInstrDesc.Chris Lattner
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
2008-01-07Rename all the M_* flags to be namespace qualified enums, and switch Chris Lattner
all clients over to using predicates instead of these flags directly. These are now private values which are only to be used to statically initialize the tables. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45692 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-07Move a bunch more accessors from TargetInstrInfo to TargetInstrDescriptorChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45680 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-07remove MachineOpCode typedef.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45679 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-07Rename MachineInstr::getInstrDescriptor -> getDesc(), which reflectsChris Lattner
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
2008-01-07Move even more functionality from MRegisterInfo into TargetInstrInfo.Owen Anderson
Some day I'll get it all moved over... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45672 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-06rename isLoad -> isSimpleLoad due to evan's desire to have such a predicate.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45667 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-04Move some more functionality from MRegisterInfo to TargetInstrInfo.Owen Anderson
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45603 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-01Move some more instruction creation methods from RegisterInfo into InstrInfo.Owen Anderson
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45484 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-01Fix a problem where lib/Target/TargetInstrInfo.h would include and useChris Lattner
a header file from libcodegen. This violates a layering order: codegen depends on target, not the other way around. The fix to this is to split TII into two classes, TII and TargetInstrInfoImpl, which defines stuff that depends on libcodegen. It is defined in libcodegen, where the base is not. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45475 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-31Move copyRegToReg from MRegisterInfo to TargetInstrInfo. This is part of theOwen Anderson
Machine-level API cleanup instigated by Chris. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45470 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-30Add new shorter predicates for testing machine operands for various types: Chris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45464 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-30Use MachineOperand::getImm instead of MachineOperand::getImmedValue. ↵Chris Lattner
Likewise setImmedValue -> setImm git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45453 91177308-0d34-0410-b5e6-96231b3b80d8

2007-09-14Remove isReg, isImm, and isMBB, and change all their users to use Dan Gohman
isRegister, isImmediate, and isMachineBasicBlock, which are equivalent, and more popular. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@41958 91177308-0d34-0410-b5e6-96231b3b80d8
2007-09-07Add lengthof and endof templates that hide a lot of sizeof computations.Owen Anderson
Patch by Sterling Stein! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@41758 91177308-0d34-0410-b5e6-96231b3b80d8
2007-07-12ARM: make branch folder remove unconditional branchesDale Johannesen
following jump tables that it earlier inserted. This would be OK on other targets but is needed for correctness only on ARM (constant islands needs to find jump tables). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@39782 91177308-0d34-0410-b5e6-96231b3b80d8

2007-06-26Revert the earlier change that removed the M_REMATERIALIZABLE machineDan Gohman
instruction flag, and use the flag along with a virtual member function hook for targets to override if there are instructions that are only trivially rematerializable with specific operands (i.e. constant pool loads). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37728 91177308-0d34-0410-b5e6-96231b3b80d8
2007-06-19Replace M_REMATERIALIZIBLE and the newly-added isOtherReMaterializableLoadDan Gohman
with a general target hook to identify rematerializable instructions. Some instructions are only rematerializable with specific operands, such as loads from constant pools, while others are always rematerializable. This hook allows both to be identified as being rematerializable with the same mechanism. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37644 91177308-0d34-0410-b5e6-96231b3b80d8
