2008-01-04Add a really quick hack at a machine code sinking pass, enabled with ↵Chris Lattner
--enable-sinking. It is missing validity checks, so it is known broken. However, it is powerful enough to compile this contrived code: void test1(int C, double A, double B, double *P) { double Tmp = A*A+B*B; *P = C ? Tmp : A; } into: _test1: movsd 8(%esp), %xmm0 cmpl $0, 4(%esp) je LBB1_2 # entry LBB1_1: # entry movsd 16(%esp), %xmm1 mulsd %xmm1, %xmm1 mulsd %xmm0, %xmm0 addsd %xmm1, %xmm0 LBB1_2: # entry movl 24(%esp), %eax movsd %xmm0, (%eax) ret instead of: _test1: movsd 16(%esp), %xmm0 mulsd %xmm0, %xmm0 movsd 8(%esp), %xmm1 movapd %xmm1, %xmm2 mulsd %xmm2, %xmm2 addsd %xmm0, %xmm2 cmpl $0, 4(%esp) je LBB1_2 # entry LBB1_1: # entry movapd %xmm2, %xmm1 LBB1_2: # entry movl 24(%esp), %eax movsd %xmm1, (%eax) ret woo. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45570 91177308-0d34-0410-b5e6-96231b3b80d8

2008-01-03don't hoist FP additions into unconditional adds + selects. This Chris Lattner

2008-01-03Remove the function attr cache for intrinsics. This does not maintain the Chris Lattner
refcount on these correctly, and can end up referring to deleted attributes. This fixes PR1881. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45525 91177308-0d34-0410-b5e6-96231b3b80d8

2008-01-02Use the new architecture to get the containing machine basic block for a machineBill Wendling
instruction. Also, use "splice" to move the new instruction instead of remove/insert (where it was leaking memory anyway). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45492 91177308-0d34-0410-b5e6-96231b3b80d8

2008-01-01Make MachineRegisterInfo::getVRegDef more efficient by aiming the keep the ↵Chris Lattner
def of the vreg at the start of the list, so the list doesn't need to be traversed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45483 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-01switch the register iterator to act more like hte LLVM value iterator: ↵Chris Lattner
dereferencing it now returns the machineinstr of the use. To get the operand, use I.getOperand(). Add a new MachineRegisterInfo::replaceRegWith, which is basically like Value::replaceAllUsesWith. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45482 91177308-0d34-0410-b5e6-96231b3b80d8

Patch by Bryan O'Sullivan! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45481 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-01Add a trivial but handy function to efficiently return the machine Chris Lattner
instruction that defines the specified vreg. Crazy. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45480 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-01Implement automatically updated def/use lists for all MachineInstr register Chris Lattner
operands. The lists are currently kept in MachineRegisterInfo, but it does not yet provide an iterator interface to them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45477 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-01Fix a bug in my previous patch: refer to the impl not the pure virtual ↵Chris Lattner
version. It's unclear why gcc would ever compile this... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45476 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
2007-12-31Fix PR1833 - eh.exception and eh.selector return twoDuncan Sands
values, which means doing extra legalization work. It would be easier to get this kind of thing right if there was some documentation... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45472 91177308-0d34-0410-b5e6-96231b3b80d8

2007-12-31update a couple of references to SSARegMap.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45468 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-31Rename SSARegMap -> MachineRegisterInfo in keeping with the idea Chris Lattner
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
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
2007-12-30More cleanups for MachineOperand:Chris Lattner
- Eliminate the static "print" method for operands, moving it into MachineOperand::print. - Change various set* methods for register flags to take a bool for the value to set it to. Remove unset* methods. - Group methods more logically by operand flavor in MachineOperand.h git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45461 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-30MachineOperand:Chris Lattner
- Add getParent() accessors. - Move SubReg out of the AuxInfo union, to make way for future changes. - Remove the getImmedValue/setImmedValue methods. - in some MachineOperand::Create* methods, stop initializing fields that are dead. MachineInstr: - Delete one copy of the MachineInstr printing code, now there is only one dump format and one copy of the code. - Make MachineOperand use the parent field to get info about preg register names if no target info is otherwise available. - Move def/use/kill/dead flag printing to the machineoperand printer, so they are always printed for an operand. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45460 91177308-0d34-0410-b5e6-96231b3b80d8
