2008-01-30A semi-gross fix for a debug info issue. When inserting the "function start" ↵Evan Cheng
label (i.e. first label in the entry block) take care to insert it at the beginning of the block. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46568 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-30Add a new PseudoSourceValue class, which will be used to help trackDan Gohman
memory reference information in the backend. Most of this was written by Florian Brander, cleanup and updating to TOT by me. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46556 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-30Factor the addressing mode and the load/store VT out of LoadSDNodeDan Gohman
and StoreSDNode into their common base class LSBaseSDNode. Member functions getLoadedVT and getStoredVT are replaced with the common getMemoryVT to simplify code that will handle both loads and stores. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46538 91177308-0d34-0410-b5e6-96231b3b80d8

2008-01-21Fix the failures in the PPC JIT by marking relocation entries forChris Lattner
external symbols (e.g. 'fmod') as needing a stub. This regression was introduced by Evan's jit patch here: http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20071231/056749.html With this fixed, the two ExecutionEngine failures are passing on ppc, and the ppc jit works on freebench and olden. This should be pulled into the 2.2 release branch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46222 91177308-0d34-0410-b5e6-96231b3b80d8

2008-01-11More CellSPU refinement and progress:Scott Michel
- Cleaned up custom load/store logic, common code is now shared [see note below], cleaned up address modes - More test cases: various intrinsics, structure element access (load/store test), updated target data strings, indirect function calls. Note: This patch contains a refactoring of the LoadSDNode and StoreSDNode structures: they now share a common base class, LSBaseSDNode, that provides an interface to their common functionality. There is some hackery to access the proper operand depending on the derived class; otherwise, to do a proper job would require finding and rearranging the SDOperands sent to StoreSDNode's constructor. The current refactor errs on the side of being conservatively and backwardly compatible while providing functionality that reduces redundant code for targets where loads and stores are custom-lowered. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45851 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-10Output sinl for a long double FSIN node, not sin.Duncan Sands
Likewise fix up a bunch of other libcalls. While there I remove NEG_F32 and NEG_F64 since they are not used anywhere. This fixes 9 Ada ACATS failures. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45833 91177308-0d34-0410-b5e6-96231b3b80d8

2008-01-07rename TargetInstrDescriptor -> TargetInstrDesc.Chris Lattner

2008-01-07Setting GlobalDirective in TargetAsmInfo by default rather thanGordon Henriksen
providing a misleading facility. It's used once in the MIPS backend and hardcoded as "\t.globl\t" everywhere else. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45676 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

2008-01-04Add 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

2008-01-01switch 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

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
