* Major calling convention code refactoring.Dan Gohman2009-08-051-5/+27
| | | | | | | | | | | | | | | | | | | | Instead of awkwardly encoding calling-convention information with ISD::CALL, ISD::FORMAL_ARGUMENTS, ISD::RET, and ISD::ARG_FLAGS nodes, TargetLowering provides three virtual functions for targets to override: LowerFormalArguments, LowerCall, and LowerRet, which replace the custom lowering done on the special nodes. They provide the same information, but in a more immediately usable format. This also reworks much of the target-independent tail call logic. The decision of whether or not to perform a tail call is now cleanly split between target-independent portions, and the target dependent portion in IsEligibleForTailCallOptimization. This also synchronizes all in-tree targets, to help enable future refactoring and feature work. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78142 91177308-0d34-0410-b5e6-96231b3b80d8

Remove dead argument from CalculateStackSlotSize(). Remove unused variable ReturnAddrIndex from various targets. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74763 91177308-0d34-0410-b5e6-96231b3b80d8

* Add an "alignment" field to the MachineFunction object. It makes more sense toBill Wendling2009-06-301-0/+2
| | | | | | | | | | | have the alignment be calculated up front, and have the back-ends obey whatever alignment is decided upon. This allows for future work that would allow for precise no-op placement and the like. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74564 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix PR3274: when promoting the condition of a BRCOND node,Duncan Sands2009-01-011-1/+1
| | | | | | | | | | | promote from i1 all the way up to the canonical SetCC type. In order to discover an appropriate type to use, pass MVT::Other to getSetCCResultType. In order to be able to do this, change getSetCCResultType to take a type as an argument, not a value (this is also more logical). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61542 91177308-0d34-0410-b5e6-96231b3b80d8
* Teach DAGCombine to fold constant offsets into GlobalAddress nodes,Dan Gohman2008-10-181-0/+2
| | | | | | | | | | | | | | | | | | | | | | | and add a TargetLowering hook for it to use to determine when this is legal (i.e. not in PIC mode, etc.) This allows instruction selection to emit folded constant offsets in more cases, such as the included testcase, eliminating the need for explicit arithmetic instructions. This eliminates the need for the C++ code in X86ISelDAGToDAG.cpp that attempted to achieve the same effect, but wasn't as effective. Also, fix handling of offsets in GlobalAddressSDNodes in several places, including changing GlobalAddressSDNode's offset from int to int64_t. The Mips, Alpha, Sparc, and CellSPU targets appear to be unaware of GlobalAddress offsets currently, so set the hook to false on those targets. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57748 91177308-0d34-0410-b5e6-96231b3b80d8

* Define CallSDNode, an SDNode subclass for use with ISD::CALL.Dan Gohman2008-09-131-1/+1
| | | | | | | | | | | | | | Currently it just holds the calling convention and flags for isVarArgs and isTailCall. And it has several utility methods, which eliminate magic 5+2*i and similar index computations in several places. CallSDNodes are not CSE'd. Teach UpdateNodeOperands to handle nodes that are not CSE'd gracefully. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56183 91177308-0d34-0410-b5e6-96231b3b80d8
* Removed SELECT_CC custom lowering. This is not needed anymore, the SELECT nodeBruno Cardoso Lopes2008-08-131-1/+3
| | | | | | | | | | | | | | | | | is lowered properly and covers everything LowerSELECT_CC did. Added method printUnsignedImm in AsmPrinter to print uimm16 operands. This avoid the ugly instruction by instruction checking in printOperand. Added a swap instruction present in the allegrex core. Added two conditional instructions present in the allegrex core : MOVZ and MOVN. They both allow a more efficient SELECT operation for integers. Also added SELECT patterns to optimize MOVZ and MOVN usage. The brcond and setcc patterns were cleaned: redundant and suboptimal patterns were removed. The suboptimals were replaced by more efficient ones. Fixed some instructions that were using immZExt16 instead of immSExt16. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54724 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | important. - Cleanup in the Subtarget info with addition of new features, not all support yet, but they allow the future inclusion of features easier. Among new features, we have : Arch family info (mips1, mips2, ...), ABI info (o32, eabi), 64-bit integer and float registers, allegrex vector FPU (VFPU), single float only support. - TargetMachine now detects allegrex core. - Added allegrex (Mips32r2) sext_inreg instructions. - *Added Float Point Instructions*, handling single float only, and aliased accesses for 32-bit FPUs. - Some cleanup in FP instruction formats and FP register classes. - Calling conventions improved to support mips 32-bit EABI. - Added Asm Printer support for fp cond codes. - Added support for sret copy to a return register. - EABI support added into LowerCALL and FORMAL_ARGS. - MipsFunctionInfo now keeps a virtual register per function to track the sret on function entry until function ret. - MipsInstrInfo FP support into methods (isMoveInstr, isLoadFromStackSlot, ...), FP cond codes mapping and initial FP Branch Analysis. - Two new Mips SDNode to handle fp branch and compare instructions : FPBrcond, FPCmp - MipsTargetLowering : handling different FP classes, Allegrex support, sret return copy, no homing location within EABI, non 32-bit stack objects arguments, and asm constraint for float. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53146 91177308-0d34-0410-b5e6-96231b3b80d8
* Wrap MVT::ValueType in a struct to get type safetyDuncan Sands2008-06-061-3/+3
| | | | | | | | | | | | | | | | | and better control the abstraction. Rename the type to MVT. To update out-of-tree patches, the main thing to do is to rename MVT::ValueType to MVT, and rewrite expressions like MVT::getSizeInBits(VT) in the form VT.getSizeInBits(). Use VT.getSimpleVT() to extract a MVT::SimpleValueType for use in switch statements (you will get an assert failure if VT is an extended value type - these shouldn't exist after type legalization). This results in a small speedup of codegen and no new testsuite failures (x86-64 linux). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52044 91177308-0d34-0410-b5e6-96231b3b80d8
