* Fix a number of clang -Wsign-compare warnings that didn't have an obviousJohn McCall2010-04-061-1/+1
| | | | | | | solution. The only reason these don't fire with gcc-4.2 is that gcc turns off part of -Wsign-compare in C++ on accident. llvm-svn: 100581

* remove TargetMachine.h #include, also, TRI isn't used frequently Chris Lattner2010-04-041-2/+2
| | | | | | enough to warrant caching in AsmPrinter, so remove it. llvm-svn: 100336
* Momentous day: remove the "O" member from AsmPrinter. Now all Chris Lattner2010-04-041-8/+4
| | | | | | | | | | "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
* convert the non-MCInstPrinter'ized EmitInstruction Chris Lattner2010-04-041-3/+5
| | | | | | | implementations to use EmitRawText instead of writing directly to "O". llvm-svn: 100318

* set SDNPVariadic on nodes throughout the rest of the targets thatChris Lattner2010-03-191-1/+1

* eliminate the now-unneeded context argument of MBB::getSymbol()Chris Lattner2010-03-131-2/+2
| | | | llvm-svn: 98451
* 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
* Fix LLVM build when the user specifies CPPFLAGS on the make command line.Jeffrey Yasskin2010-03-121-1/+1

* Change the Value argument to eliminateFrameIndex to a type-tagged value. ThisJim Grosbach2010-03-092-2/+2
| | | | | | | | | | 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
* fix a type compatibility bug. imm is i32 in the input Chris Lattner2010-03-082-1/+6

* Sink InstructionSelect() out of each target into SDISel, and rename itChris Lattner2010-03-021-49/+7
| | | | | | | | | | | | 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(-) llvm-svn: 97555

* Split SelectionDAGISel::IsLegalAndProfitableToFold toEvan Cheng2010-02-151-2/+1
| | | | | | | | IsLegalToFold and IsProfitableToFold. The generic version of the later simply checks whether the folding candidate has a single use. This allows the target isel routines more flexibility in deciding whether folding makes sense. The specific case we are interested in is folding constant pool loads with multiple uses. llvm-svn: 96255
* Remove an assumption of default arguments. This is in anticipation of aDavid Greene2010-02-151-3/+5

* print all the newlines at the end of instructions withChris Lattner2010-02-101-1/+1
| | | | | | OutStreamer.AddBlankLine instead of textually. llvm-svn: 95734
* move target-independent opcodes out of TargetInstrInfoChris Lattner2010-02-091-8/+8
| | | | | | | | | 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. llvm-svn: 95687
* rejigger the world so that EmitInstruction prints the \n atChris Lattner2010-02-031-0/+1

* Remove the argument from EmitJumpTableInfo, because it doesn't need it.Chris Lattner2010-01-281-1/+1
| | | | | | | | Move the X86 implementation of function body emission up to AsmPrinter::EmitFunctionBody, which works by calling the virtual EmitInstruction method. llvm-svn: 94716

* 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
* constify a method argument.Chris Lattner2010-01-262-4/+5
| | | | llvm-svn: 94612
* Eliminate SetDirective, and replace it with HasSetDirective.Chris Lattner2010-01-261-1/+0
| | | | | | | | | | | 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. All of these except pic16 are normal ELF targets, so they almost certainly have it. llvm-svn: 94585
* add a new MachineBasicBlock::getSymbol method, replacingChris Lattner2010-01-261-2/+2

* resolve a fixme: the "nonexecutable stack directive" is actuallyChris Lattner2010-01-232-2/+7
| | | | | | | | | a .section. Switch to it with SwitchSection. However, I think that this directive should be safe on any ELF target. If so, we should hoist it up out of the X86 and SystemZ targets. llvm-svn: 94298
* Stop building RTTI information for *most* llvm libraries. NotableChris Lattner2010-01-223-0/+4
| | | | | | | | | | | missing ones are libsupport, libsystem and libvmcore. libvmcore is currently blocked on bugpoint, which uses EH. Once it stops using EH, we can switch it off. This #if 0's out 3 unit tests, because gtest requires RTTI information. Suggestions welcome on how to fix this. llvm-svn: 94164
* revert 93934, removing the MCAsmInfo endianness bit. I can'tChris Lattner2010-01-201-2/+1
| | | | | | | stomache MCAsmInfo having this, and I found a better solution to this layering issue. llvm-svn: 93985
* give MCAsmInfo a 'has little endian' bit. This is unfortunate, butChris Lattner2010-01-191-1/+2
| | | | | | | | | I really want clients of the streamer to be able to say "emit this 64-bit integer" and have it get broken down right by the streamer. I may change this in the future, we'll see how it works out. llvm-svn: 93934
* Now that we have everything nicely factored (e.g. asmprinter is notChris Lattner2010-01-191-82/+0
| | | | | | | | | | | | | | | | | | | | | | | doing global variable classification anymore) and hookized, sink almost all target targets global variable emission code into AsmPrinter and out of each target. Some notes: 1. PIC16 does completely custom and crazy stuff, so it is not changed. 2. XCore has some custom handling for extra directives. I'll look at it next. 3. This switches linux/ppc to use .globl instead of .global. If .globl is actually wrong, let me know and I'll fix it. 4. This makes linux/ppc get a lot of random cases right which were obviously wrong before, it is probably now a bit healthier. 5. Blackfin will probably start getting .comm and other things that it didn't before. If this is undesirable, it should explicitly opt out of these things by clearing the relevant fields of MCAsmInfo. This leads to a nice diffstat: 14 files changed, 127 insertions(+), 830 deletions(-) llvm-svn: 93858
* introduce a section kind for common linkage. Use this to slightlyChris Lattner2010-01-191-1/+1
| | | | | | | | | simplify and commonize some of the asmprinter logic for globals. This also avoids printing the MCSection for .zerofill, which broke the llvm-gcc build. llvm-svn: 93843
* now that MCSymbol::print doesn't use it's MAI argument, we can Chris Lattner2010-01-171-47/+20
| | | | | | | remove it and change all the code that prints MCSymbols to use << instead, which is much simpler and cleaner. llvm-svn: 93695
* remove the string form of printVisibility.Chris Lattner2010-01-161-13/+4
