2010-07-07Split the SDValue out of OutputArg so that SelectionDAG-independentDan Gohman
code can do calling-convention queries. This obviates OutputArgReg. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107786 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-17Use const qualifiers with TargetLowering. This eliminates severalDan Gohman
const_casts, and it reinforces the design of the Target classes being immutable. SelectionDAGISel::IsLegalToFold is now a static member function, because PIC16 uses it in an unconventional way. There is more room for API cleanup here. And PIC16's AsmPrinter no longer uses TargetLowering. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101635 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-27Eliminate target hook IsEligibleForTailCallOptimization.Evan Cheng
Target independent isel should always pass along the "tail call" property. Change target hook LowerCall's parameter "isTailCall" into a refernce. If the target decides it's impossible to honor the tail call request, it should set isTailCall to false to make target independent isel happy. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94626 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.

2009-10-28Update SystemZ to use PSW following the way x86 uses EFLAGS. BesidesDan Gohman
eliminating a use of MVT::Flag, this is needed for an upcoming CodeGen change. This unfortunately requires SystemZ to switch to the list-burr scheduler, in order to handle the physreg defs properly, however that's what LLVM has available at this time. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85357 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-19Fix PR4926. When target hook EmitInstrWithCustomInserter() insert new basic ↵Evan Cheng

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
2009-07-28Rip 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
