llvm-svn: 105322
 2010-06-02 13:53:17 +00:00
Dan Gohman 062a97f0f6 BR is a barrier. 
llvm-svn: 103826
 2010-05-14 22:00:27 +00:00
Dan Gohman bb919dfb6b Implement a bunch more TargetSelectionDAGInfo infrastructure. 
Move EmitTargetCodeForMemcpy, EmitTargetCodeForMemset, and
EmitTargetCodeForMemmove out of TargetLowering and into
SelectionDAGInfo to exercise this.

llvm-svn: 103481
 2010-05-11 17:31:57 +00:00
Dan Gohman 779c69bbc5 Add a DebugLoc argument to TargetInstrInfo::copyRegToReg, so that it 
doesn't have to guess.

llvm-svn: 103194
 2010-05-06 20:33:48 +00:00
Evan Cheng efb126a665 Add argument TargetRegisterInfo to loadRegFromStackSlot and storeRegToStackSlot. 
llvm-svn: 103193
 2010-05-06 19:06:44 +00:00
Dan Gohman f62cd20b62 No-ops emitted for scheduling don't correspond with anything in the 
user's source, so don't arbitrarily assign them a debug location.

llvm-svn: 103121
 2010-05-05 20:58:01 +00:00
Dan Gohman 25c1653700 Get rid of the EdgeMapping map. Instead, just check for BasicBlock 
changes before doing phi lowering for switches.

llvm-svn: 102809
 2010-05-01 00:01:06 +00:00
Dan Gohman 0cb06d64e8 Fix a typo. 
llvm-svn: 102799
 2010-04-30 22:38:11 +00:00
Devang Patel 12f6855f85 Use MachineOperand::is* predicates. 
llvm-svn: 102472
 2010-04-27 22:24:37 +00:00
Anton Korobeynikov 7d62e33291 Make processor FUs unique for given itinerary. This extends the limit of 32 
FU per CPU arch to 32 per intinerary allowing precise modelling of quite
complex pipelines in the future.

llvm-svn: 101754
 2010-04-18 20:31:01 +00:00
Dan Gohman 8422e57baa Delete now-unnecessary const_casts. 
llvm-svn: 101637
 2010-04-17 15:32:28 +00:00
Dan Gohman 21cea8ac2e Use const qualifiers with TargetLowering. This eliminates several 
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
 2010-04-17 15:26:15 +00:00
Dan Gohman 31ae586c74 Move per-function state out of TargetLowering subclasses and into 
MachineFunctionInfo subclasses.

llvm-svn: 101634
 2010-04-17 14:41:14 +00:00
Dan Gohman 9becdddc49 Add skeleton target-specific SelectionDAGInfo files. 
llvm-svn: 101564
 2010-04-16 23:04:22 +00:00
Dan Gohman bcaf681cde Add const qualifiers to CodeGen's use of LLVM IR constructs. 
llvm-svn: 101334

Benjamin Kramer a6769269f3 Use twines to simplify calls to report_fatal_error. For code size and readability. 
llvm-svn: 100756
 2010-04-08 10:44:28 +00:00
Chris Lattner 2104b8d36e rename llvm::llvm_report_error -> llvm::report_fatal_error 
llvm-svn: 100709
 2010-04-07 22:58:41 +00:00
Chris Lattner a49ac8ace0 prune some #includes. 
llvm-svn: 100399
 2010-04-05 04:04:10 +00:00
Jakob Stoklund Olesen b93331f3be Replace TSFlagsFields and TSFlagsShifts with a simpler TSFlags field. 
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.

Chris Lattner d20699bc87 Momentous day: remove the "O" member from AsmPrinter. Now all 
"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
 2010-04-04 08:18:47 +00:00
Chris Lattner 5e5961864f mcize a bunch more stuff, using EmitRawText for things we 
don't have mcstreamer support for yet.

llvm-svn: 100319
 2010-04-04 07:05:53 +00:00
Chris Lattner 3d86cd6710 convert the non-MCInstPrinter'ized EmitInstruction 
implementations to use EmitRawText instead of writing
directly to "O".

llvm-svn: 100318
 2010-04-04 06:12:20 +00:00
Chris Lattner 3bb09768cb fix PrintAsmOperand and PrintAsmMemoryOperand to pass down 
raw_ostream to print to.

llvm-svn: 100313
 2010-04-04 05:29:35 +00:00
Chris Lattner 76c564b1bb change a ton of code to not implicitly use the "O" raw_ostream 
member of AsmPrinter.  Instead, pass it in explicitly.

llvm-svn: 100306
 2010-04-04 04:47:45 +00:00
Chris Lattner 6f306d7d30 use DebugLoc default ctor instead of DebugLoc::getUnknownLoc()

Dale Johannesen 4244d12769 Teach AnalyzeBranch, RemoveBranch and the branch 
folder to be tolerant of debug info following the
branch(es) at the end of a block.

llvm-svn: 98451
 2010-03-13 21:04:28 +00:00
Chris Lattner e468f88b26 rearrange MCContext ownership. Before LLVMTargetMachine created it 
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.

Chris Lattner 0b822ab447 inline GetGlobalValueSymbol into the rest its callers and 
remove it.

 2010-03-12 21:19:23 +00:00
Jim Grosbach fae913adf8 Change the Value argument to eliminateFrameIndex to a type-tagged value. This 
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.

Andrew Lenharth a8e87d57be Fix PR6444, note still doesn't compile libgcc2 all the way, but fixes that error. May not fix it in an ABI complient way. It wasn't clear what gcc does

Chris Lattner f98f124a73 Sink InstructionSelect() out of each target into SDISel, and rename it 
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.

OutStreamer.AddBlankLine instead of textually.

Chris Lattner b06015aa69 move target-independent opcodes out of TargetInstrInfo 
into TargetOpcodes.h.  #include the new TargetOpcodes.h
into MachineInstr.  Add new inline accessors (like isPHI())
to MachineInstr, and start using them throughout the 
codebase.

Chris Lattner 996ec840d0 rejigger the world so that EmitInstruction prints the \n at 
the end of the instruction instead of expecting the caller to
do it.  This currently causes the asm-verbose instruction 
comments to be on the next line.

Chris Lattner b0d44c3807 refactor code so that LLVMTargetMachine creates the asmstreamer and 
mccontext instead of having AsmPrinter do it.  This allows other 
types of MCStreamer's to be passed in.
