* Use const qualifiers with TargetLowering. This eliminates severalDan Gohman2010-04-174-17/+19
| | | | | | | | | | | | | 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. llvm-svn: 101635

* Replace TSFlagsFields and TSFlagsShifts with a simpler TSFlags field.Jakob Stoklund Olesen2010-04-051-5/+1
| | | | | | | | | | | | | | | | | | | 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. llvm-svn: 100384
* Momentous day: remove the "O" member from AsmPrinter. Now all Chris Lattner2010-04-041-5/+3
| | | | | | | | | | "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. llvm-svn: 100327

* rearrange MCContext ownership. Before LLVMTargetMachine created it Chris Lattner2010-03-131-3/+2
| | | | | | | | | | | 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. llvm-svn: 98450

* Eliminate target hook IsEligibleForTailCallOptimization.Evan Cheng2010-01-272-2/+4
| | | | | | | | | 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. llvm-svn: 94626

These include Blackfin, Mips, Alpha, and PIC16. All of these except pic16 are normal ELF targets, so they almost certainly have it. llvm-svn: 94585
