2010-04-21Implement -disable-non-leaf-fp-elim which disable frame pointer eliminationEvan Cheng
optimization for non-leaf functions. This will be hooked up to gcc's -momit-leaf-frame-pointer option. rdar://7886181 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101984 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-18Make processor FUs unique for given itinerary. This extends the limit of 32Anton Korobeynikov
FU per CPU arch to 32 per intinerary allowing precise modelling of quite complex pipelines in the future. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101754 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

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100399 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-05Replace TSFlagsFields and TSFlagsShifts with a simpler TSFlags field.Jakob Stoklund Olesen
When a target instruction wants to set target-specific flags, it should simply set bits in the TSFlags bit vector defined in the Instruction TableGen class. This works well because TableGen resolves member references late: class I : Instruction { AddrMode AM = AddrModeNone; let TSFlags{3-0} = AM.Value; } let AM = AddrMode4 in def ADD : I; TSFlags gets the expected bits from AddrMode4 in this example. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100384 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-04Momentous day: remove the "O" member from AsmPrinter. Now all Chris Lattner
"asm printering" happens through MCStreamer. This also Streamerizes PIC16 debug info, which escaped my attention. This removes a leak from LLVMTargetMachine of the 'legacy' output stream. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100327 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-13rearrange MCContext ownership. Before LLVMTargetMachine created it Chris Lattner
and passing off ownership to AsmPrinter. Now MachineModuleInfo creates it and owns it by value. This allows us to use MCSymbols more consistently throughout the rest of the code generator, and simplifies a bit of code. This also allows MachineFunction to keep an MCContext reference handy, and cleans up the TargetRegistry interfaces for AsmPrinters. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98450 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-09Change the Value argument to eliminateFrameIndex to a type-tagged value. ThisJim Grosbach
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98086 91177308-0d34-0410-b5e6-96231b3b80d8

DoInstructionSelection. Inline "SelectRoot" into it from DAGISelHeader. Sink some other stuff out of DAGISelHeader into SDISel. Eliminate the various 'Indent' stuff from various targets, which dates to when isel was recursive. 17 files changed, 114 insertions(+), 430 deletions(-) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97555 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

Default HasSetDirective to true, since most targets have it. The targets that claim to not have it probably do, or it is spelled differently. These include Blackfin, Mips, Alpha, and PIC16.
