* Rename "HasCalls" in MachineFrameInfo to "AdjustsStack" to better describe whatBill Wendling2010-05-141-5/+5
| | | | | | | | | the variable actually tracks. N.B., several back-ends are using "HasCalls" as being synonymous for something that adjusts the stack. This isn't 100% correct and should be looked into. llvm-svn: 103802

* Change the Value argument to eliminateFrameIndex to a type-tagged value. ThisJim Grosbach2010-03-091-1/+1
| | | | | | | | | | is preparatory to having PEI's scavenged frame index value reuse logic properly distinguish types of frame values (e.g., whether the value is stack-pointer relative or frame-pointer relative). No functionality change. llvm-svn: 98086

It's too easy to pass a wrong argument value when multiple arguments have default values. Make everything explicit to trap bugs early.

* Add register-reuse to frame-index register scavenging. When a target usesJim Grosbach2009-10-071-3/+4
| | | | | | | | | | | | | | | | | | | | a virtual register to eliminate a frame index, it can return that register and the constant stored there to PEI to track. When scavenging to allocate for those registers, PEI then tracks the last-used register and value, and if it is still available and matches the value for the next index, reuses the existing value rather and removes the re-materialization instructions. Fancier tracking and adjustment of scavenger allocations to keep more values live for longer is possible, but not yet implemented and would likely be better done via a different, less special-purpose, approach to the problem. eliminateFrameIndex() is modified so the target implementations can return the registers they wish to be tracked for reuse. ARM Thumb1 implements and utilizes the new mechanism. All other targets are simply modified to adjust for the changed eliminateFrameIndex() prototype. llvm-svn: 83467

* remove various std::ostream version of printing methods fromChris Lattner2009-08-231-6/+6

* Major calling convention code refactoring.Dan Gohman2009-08-051-3/+3
| | | | | | | | | | | | | | | | | | | 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. llvm-svn: 78142
* More migration to raw_ostream, the water has dried up around the iostream hole.Daniel Dunbar2009-07-251-1/+2
| | | | | | | | | | - Some clients which used DOUT have moved to DEBUG. We are deprecating the "magic" DOUT behavior which avoided calling printing functions when the statement was disabled. In addition to being unnecessary magic, it had the downside of leaving code in -Asserts builds, and of hiding potentially unnecessary computations. llvm-svn: 77019
* llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable.Torok Edwin2009-07-141-4/+4
| | | | | | | | | 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"). llvm-svn: 75640
* assert(0) -> LLVM_UNREACHABLE.Torok Edwin2009-07-111-4/+5
| | | | | | | | | 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. llvm-svn: 75379

* Added Mips support for DYNAMIC_STACKALLOCBruno Cardoso Lopes2008-08-071-0/+3
| | | | | | | | | Fixed bug in adjustMipsStackFrame, which was breaking while trying to access a dead stack object index. Also added one more alignment before fixing the callee saved registers stack offset adjustment. llvm-svn: 54485
* Added support for fp callee saved registers.Bruno Cardoso Lopes2008-08-061-84/+170
| | | | | | | | | | | | | | | | | | | | | Added fp register clobbering during calls. Added AsmPrinter support for "fmask", a bitmask that indicates where on the stack the fp callee saved registers are. Fixed the stack frame layout for Mips, now the callee saved regs are in the right stack location (a little documentation about how this stack frame must look like is present in MipsRegisterInfo.cpp). This was done using the method MipsRegisterInfo::adjustMipsStackFrame To be more clear, these are examples of what is solves : 1) FP and RA are also callee saved, and despite they aren't in CSI they must be saved before the fp callee saved registers. 2) The ABI requires that local varibles are allocated before the callee saved register area, the opposite behavior from the default allocation. 3) CPU and FPU saved register area must be aligned independent of each other. llvm-svn: 54403

* Added Subtarget support into RegisterInfoBruno Cardoso Lopes2008-07-141-8/+14
| | | | | | | | | | | | Added HasABICall and HasAbsoluteCall (equivalent to gcc -mabicall and -mno-shared). HasAbsoluteCall is not implemented but HasABICall is the default for o32 ABI. Now, both should help into a more accurate relocation types implementation. Added IsLinux is needed to choose between asm directives. Instruction name strings cleanup. AsmPrinter improved. llvm-svn: 53551
* Several changes to Mips backend, experimental fp support being the mostBruno Cardoso Lopes2008-07-051-38/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. llvm-svn: 53146

| | | | | | | | | | | | 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. llvm-svn: 45464
