2013-03-14[mips] Set isAllocatable bit of unallocatable register classes to 0.Akira Hatanaka
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177128 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-14Add a new method which enables one to change register classes.Reed Kotler
See the Mips16ISetLowering.cpp patch to see a use of this. For now now the extra code in Mips16ISetLowering.cpp is a nop but is used for test purposes. Mips32 registers are setup and then removed and then the Mips16 registers are setup. Normally you need to add register classes and then call computeRegisterProperties. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177120 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-14Provide the register scavenger to processFunctionBeforeFrameFinalizedHal Finkel
Add the current PEI register scavenger as a parameter to the processFunctionBeforeFrameFinalized callback. This change is necessary in order to allow the PowerPC target code to set the register scavenger frame index after the save-area offset adjustments performed by processFunctionBeforeFrameFinalized. Only after these adjustments have been made is it possible to estimate the size of the stack frame. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177108 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-08DAGCombiner: Use correct value type for checking legality of BR_CC v3Tom Stellard
LegalizeDAG.cpp uses the value of the comparison operands when checking the legality of BR_CC, so DAGCombiner should do the same. v2: - Expand more BR_CC value types for NVPTX v3: - Expand correct BR_CC value types for Hexagon, Mips, and XCore. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176694 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-05[mips] Remove android calling convention.Akira Hatanaka
This calling convention was added just to handle functions which return vector of floats. The fix committed in r165585 solves the problem. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176530 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-04[mips] Print move instructions.Akira Hatanaka
"move $4, $5" is printed instead of "or $4, $5, $zero". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176455 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-01[mips] Fix inefficient code generation.Akira Hatanaka
This patch eliminates the need to emit a constant move instruction when this pattern is matched: (select (setgt a, Constant), T, F) The pattern above effectively turns into this: (conditional-move (setlt a, Constant + 1), F, T) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176384 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-01Fix PR10475Michael Liao
- ISD::SHL/SRL/SRA must have either both scalar or both vector operands but TLI.getShiftAmountTy() so far only return scalar type. As a result, backend logic assuming that breaks. - Rename the original TLI.getShiftAmountTy() to TLI.getScalarShiftAmountTy() and re-define TLI.getShiftAmountTy() to return target-specificed scalar type or the same vector type as the 1st operand. - Fix most TICG logic assuming TLI.getShiftAmountTy() a simple scalar type. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176364 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-24Make psuedo FEXT_T8I816_ins a custom inserter. It should be expandedReed Kotler
as early as possible; which means during instruction selection. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175984 91177308-0d34-0410-b5e6-96231b3b80d8

macros.The rest is some small misc. stuff. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175950 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-22[mips] Emit call16 operator instead of got_disp. The former allows lazy binding.Akira Hatanaka

2013-02-21Move the eliminateCallFramePseudoInstr method from TargetRegisterInfoEli Bendersky
to TargetFrameLowering, where it belongs. Incidentally, this allows us to delete some duplicated (and slightly different!) code in TRI. There are potentially other layering problems that can be cleaned up as a result, or in a similar manner. The refactoring was OK'd by Anton Korobeynikov on llvmdev. Note: this touches the target interfaces, so out-of-tree targets may be affected. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175788 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-21Expand the sel pseudo/macro. This generates basic blocks where previouslyReed Kotler
there were inline br .+4 instructions. Soon everything can enjoy the full instruction scheduling experience. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175718 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-21Mips specific standalone assembler addressing mode %hi and %lo.Jack Carter
The constructs %hi() and %lo() represent the high and low 16 bits of the address. Because the 16 bit offset field of an LW instruction is interpreted as signed, if bit 15 of the low part is 1 then the low part will act as a negative and 1 needs to be added to the high part. Contributer: Vladimir Medic git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175707 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-20ELF symbol table field st_other support, Jack Carter
excluding visibility bits. Mips specific standalone assembler directive "set at". This directive changes the general purpose register that the assembler will use when given the symbolic register name $at. This does not include negative testing. That will come in a future patch. A side affect of this patch recognizes the different GPR register names for temporaries between old abi and new abi so a test case for that is included.
