2009-11-24Make capitalization of names starting "is" more consistent.Dale Johannesen
No functional change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@89724 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-23Remove ISD::DEBUG_LOC and ISD::DBG_LABEL, which are no longer used.Dan Gohman
Note that "hasDotLocAndDotFile"-style debug info was already broken; people wanting this functionality should implement it in the AsmPrinter/DwarfWriter code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@89711 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-20Target-independent support for TargetFlags on BlockAddress operands,Dan Gohman
and support for blockaddresses in x86-32 PIC mode. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@89506 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-13Adjust isConstantSplat to allow for big-endian targets.Dale Johannesen
PPC is such a target; make it work. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@87060 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-12Add a bool flag to StackObjects telling whether they reference spillDavid Greene
slots. The AsmPrinter will use this information to determine whether to print a spill/reload comment. Remove default argument values. It's too easy to pass a wrong argument value when multiple arguments have default values. Make everything explicit to trap bugs early. Update all targets to adhere to the new interfaces.. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@87022 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-04Add PowerPC codegen for indirect branches.Bob Wilson
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@86050 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-18-Revert parts of 84326 and 84411. Distinquishing between fixed and non-fixedEvan Cheng
stack slots and giving them different PseudoSourceValue's did not fix the problem of post-alloc scheduling miscompiling llvm itself. - Apply Dan's conservative workaround by assuming any non fixed stack slots can alias other memory locations. This means a load from spill slot #1 cannot move above a store of spill slot #2. - Enable post-alloc scheduling for x86 at optimization leverl Default and above. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84424 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84321 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-17Rename getFixedStack to getStackObject. The stack objects represented are notEvan Cheng
necessarily fixed. Only those will negative frame indices are "fixed." git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84315 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-27LBRX no longer has an explicit SrcValueSDNode operand, so the typeDan Gohman
operand is now at index 2, rather than 3. This fixes the "Invalid child # of SDNode!" failures on PowerPC. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82942 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-25Improve MachineMemOperand handling.Dan Gohman
- Allocate MachineMemOperands and MachineMemOperand lists in MachineFunctions. This eliminates MachineInstr's std::list member and allows the data to be created by isel and live for the remainder of codegen, avoiding a lot of copying and unnecessary translation. This also shrinks MemSDNode. - Delete MemOperandSDNode. Introduce MachineSDNode which has dedicated fields for MachineMemOperands. - Change MemSDNode to have a MachineMemOperand member instead of its own fields with the same information. This introduces some redundancy, but it's more consistent with what MachineInstr will eventually want. - Ignore alignment when searching for redundant loads for CSE, but remember the greatest alignment. Target-specific code which previously used MemOperandSDNodes with generic SDNodes now use MemIntrinsicSDNodes, with opcodes in a designated range so that the SelectionDAG framework knows that MachineMemOperand information is available. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82794 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-25Rename getTargetNode to getMachineNode, for consistency with theDan Gohman
naming scheme used in SelectionDAG, where there are multiple kinds of "target" nodes, but "machine" nodes are nodes which represent a MachineInstr. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82790 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-25Don't try to use pre-indexed addressing with sthbrx/stwbrxDan Gohman
instructions. This fixes a PowerPC bug exposed by some unrelated changes I'm working on. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82743 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-19Fix PR4926. When target hook EmitInstrWithCustomInserter() insert new basic ↵Evan Cheng
blocks and update CFG, it should also inform sdisel of the changes so the phi source operands will come from the right basic blocks. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82311 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-18Enhance EmitInstrWithCustomInserter() so target can specify CFG changes that ↵Evan Cheng
sdisel will use to properly complete phi nodes. Not functionality change yet. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82273 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-06Remove some not-really-used variables, as warnedDuncan Sands

2009-08-29- Add target lowering methods to get the preferred format for the FDE and LSDABill Wendling
encodings. - Make some of the values emitted by the FDEs dependent upon the pointer size. This is in line with how GCC does things. And it has the benefit of working for Darwin in 64-bit mode now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80428 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-15Add support for the PowerPC 64-bit SVR4 ABI.Tilmann Scheller
The Link Register is volatile when using the 32-bit SVR4 ABI. Make it possible to use the 64-bit SVR4 ABI. Add non-volatile registers for the 64-bit SVR4 ABI. Make sure r2 is a reserved register when using the 64-bit SVR4 ABI. Update PPCFrameInfo for the 64-bit SVR4 ABI. Add FIXME for 64-bit Darwin PPC. Insert NOP instruction after direct function calls. Emit official procedure descriptors. Create TOC entries for GlobalAddress references. Spill 64-bit non-volatile registers to the correct slots. Only custom lower VAARG when using the 32-bit SVR4 ABI. Use simple VASTART lowering for the 64-bit SVR4 ABI. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79091 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-12Add contexts to some of the MVT APIs. No functionality change yet, just the ↵Owen Anderson
infrastructure work needed to get the contexts to where they need to be first. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78759 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-10Start moving TargetLowering away from using full MVTs and towards ↵Owen Anderson
SimpleValueType, which will simplify the privatization of IntegerType in the future. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78584 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-081. Make MCSection an abstract class.Chris Lattner
2. Move section switch printing to MCSection virtual method which takes a TAI. This eliminates textual formatting stuff from TLOF. 3. Eliminate SwitchToSectionDirective, getSectionFlagsAsString, and TLOFELF::AtIsCommentChar. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78510 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-05Major calling convention code refactoring.Dan Gohman
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
2009-08-02Normalize Subtarget constructors to take a target triple string instead ofDaniel Dunbar
Module*. Also, dropped uses of TargetMachine where unnecessary. The only target which still takes a TargetMachine& is Mips, I would appreciate it if someone would normalize this to match other targets. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77918 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-28the apple "ld_classic" linker doesn't support .literal16 in 32-bitChris Lattner

2009-07-28Rip all of the global variable lowering logic out of TargetAsmInfo. SinceChris Lattner
it is highly specific to the object file that will be generated in the end, this introduces a new TargetLoweringObjectFile interface that is implemented for each of ELF/MachO/COFF/Alpha/PIC16 and XCore. Though still is still a brutal and ugly refactoring, this is a major step towards goodness. This patch also: 1. fixes a bunch of dangling pointer problems in the PIC16 backend. 2. disables the TargetLowering copy ctor which PIC16 was accidentally using. 3. gets us closer to xcore having its own crazy target section flags and pic16 not having to shadow sections with its own objects. 4. fixes wierdness where ELF targets would set CStringSection but not CStringSection_. Factor the code better. 5. fixes some bugs in string lowering on ELF targets. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77294 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-14llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable.Torok Edwin
This adds location info for all llvm_unreachable calls (which is a macro now) in !NDEBUG builds. In NDEBUG builds location info and the message is off (it only prints "UREACHABLE executed"). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75640 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-11assert(0) -> LLVM_UNREACHABLE.Torok Edwin
Make llvm_unreachable take an optional string, thus moving the cerr<< out of line. LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for NDEBUG builds. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75379 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-03Refactor ABI code in the PowerPC backend.Tilmann Scheller
Make CalculateParameterAndLinkageAreaSize() Darwin-specific. Remove SVR4 specific code from LowerCALL_Darwin() and LowerFORMAL_ARGUMENTS_Darwin(). Rename MachoABI to DarwinABI for consistency. Rename ELF ABI to SVR4 ABI for consistency. Factor out common call return lowering between the Darwin and SVR4 ABI. Factor out common call lowering between the Darwin and SVR4 ABI. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74766 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-03Implement the SVR4 ABI for PowerPC.Tilmann Scheller
Implement LowerFORMAL_ARGUMENTS_SVR4(). Implement LowerCALL_SVR4(). Add support for split arguments. Implement by value parameter passing for aggregates. Add support for variable argument lists. Create the spill area for argument registers of variable argument functions no longer at a fixed offset. Make sure callee saved registers are spilled to the correct stack offsets. Change allocation order of non-volatile floating-point registers. Add VRSAVE to the list of callee-saved registers, add CallConvLowering for vararg calls. Add support for variable argument calls with Vector arguments. Add support for VR and VRSAVE save area, improve allocation order for non-volatile vector registers. Stop creating illegal i8 values in LowerVASTART(). Add memory access width hints. Make sure to reserve space on the stack for the frame pointer. When using the SVR4 ABI, reserve r13 for the Small Data Area pointer. Assure that the frame pointer is spilled to the correct location on the stack. Some FP registers were not marked as volatile. Make sure the i64 words from a long double are passed either both in registers or both on the stack. Only put integer arguments in registers which are not marked with the inreg flag. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74765 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-03Add NumFixedArgs attribute to CallSDNode which indicates the number of fixed ↵Tilmann Scheller
arguments in a vararg call. With the SVR4 ABI on PowerPC, vector arguments for vararg calls are passed differently depending on whether they are a fixed or a variable argument. Variable vector arguments always go into memory, fixed vector arguments are put into vector registers. If there are no free vector registers available, fixed vector arguments are put on the stack. The NumFixedArgs attribute allows to decide for an argument in a vararg call whether it belongs to the fixed or variable portion of the parameter list. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74764 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-03Small cleanups in the PowerPC backend.Tilmann Scheller
Small refactoring in LowerFORMAL_ARGUMENTS(). Correct minor formatting issues. Remove size argument of CreateCopyOfByValArgument(). 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

2009-06-30Add an "alignment" field to the MachineFunction object. It makes more sense toBill Wendling
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
2009-06-04Fix FP_TO_UINT->i32 on ppc32 -mcpu=g5. This wasDale Johannesen
using Promote which won't work because i64 isn't a legal type. It's easy enough to use Custom, but then we have the problem that when the type legalizer is promoting FP_TO_UINT->i16, it has no way of telling it should prefer FP_TO_SINT->i32 to FP_TO_UINT->i32. I have uncomfortably hacked this by making the type legalizer choose FP_TO_SINT when both are Custom. This fixes several regressions in the testsuite. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72891 91177308-0d34-0410-b5e6-96231b3b80d8
