* constify a bunch of dwarf stuff now that the registerinfo methodChris Lattner2010-01-266-13/+13
| | | | | | is constified. llvm-svn: 94613
* Allow some automatic tailcall optimization without changing ABI.Evan Cheng2010-01-261-6/+1
| | | | llvm-svn: 94611
* emit jump table an alias ".set" directives through MCStreamer as Chris Lattner2010-01-262-4/+10
| | | | | | | | | | | | assignments. .set x, a-b is the same as: x = a-b llvm-svn: 94596
* Use AssertingVH, just to be paranoid.Devang Patel2010-01-261-2/+4
| | | | llvm-svn: 94593
* Emit DW_AT_containing_type attribute for a class if containing type is known.Devang Patel2010-01-261-0/+5
| | | | llvm-svn: 94587
* Eliminate SetDirective, and replace it with HasSetDirective.Chris Lattner2010-01-262-7/+7
| | | | | | | | | | | 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
* eliminate MCAsmInfo::NeedsSet: we now just use .set on any platformChris Lattner2010-01-262-8/+5
| | | | | | that has it. llvm-svn: 94581
* eliminate the TargetLowering::UsesGlobalOffsetTable bool, which isChris Lattner2010-01-262-11/+11
| | | | | | | subsumed by TargetLowering::getJumpTableEncoding(). Change uses of it to be more specific. llvm-svn: 94529
* Now that printPICJumpTableSetLabel is not overloaded,Chris Lattner2010-01-261-22/+18
| | | | | | | inline it into its only caller, allowing us to simplify it and hoist bits out of the loop. llvm-svn: 94528
* Move getJTISymbol from MachineJumpTableInfo to MachineFunction,Chris Lattner2010-01-263-25/+27
| | | | | | | | | | | | | | | | | | which is more convenient, and change getPICJumpTableRelocBaseExpr to take a MachineFunction to match. Next, move the X86 code that create a PICBase symbol to X86TargetLowering::getPICBaseSymbol from X86MCInstLower::GetPICBaseSymbol, which was an asmprinter specific library. This eliminates a 'gross hack', and allows us to implement X86ISelLowering::getPICJumpTableRelocBaseExpr which now calls it. This in turn allows us to eliminate the X86AsmPrinter::printPICJumpTableSetLabel method, which was the only overload of printPICJumpTableSetLabel. llvm-svn: 94526
* add a new MachineJumpTableInfo::getJTISymbol method,Chris Lattner2010-01-263-20/+40
| | | | | | use it to implement the default TargetLowering::getPICJumpTableRelocBaseExpr llvm-svn: 94523
* stub out a new target hook, need some refactoring before I canChris Lattner2010-01-261-0/+11
| | | | | | implement it. llvm-svn: 94521
* simplify asmprinter: only emit .set directives when entries haveChris Lattner2010-01-261-5/+7
| | | | | | | EK_LabelDifference32 kind and the target has .set support. Simplify X86AsmPrinter::printPICJumpTableSetLabel to make use of recent helpers. llvm-svn: 94518
* rename printPICJumpTableEntry -> EmitJumpTableEntry,Chris Lattner2010-01-261-19/+10
| | | | | | | make it private and non-virtual. It handles the non-pic case too, so just use it, simplifying EmitJumpTableInfo. llvm-svn: 94517
* add a new MachineBasicBlock::getSymbol method, replacingChris Lattner2010-01-262-15/+23
| | | | | | the AsmPrinter::GetMBBSymbol. llvm-svn: 94515
* New PBQP solver.Lang Hames2010-01-2612-2056/+1503
| | | | | | | | | * Fixed a reduction bug which occasionally led to infinite-cost (invalid) register allocation solutions despite the existence finite-cost solutions. * Significantly reduced memory usage (>50% reduction). * Simplified a lot of the solver code. llvm-svn: 94514
* make MachineFunction keep track of its ID and make Chris Lattner2010-01-263-8/+14
| | | | | | | | MachineFunctionAnalysis dole them out, instead of having AsmPrinter do both. Have the AsmPrinter::SetupMachineFunction method set the 'AsmPrinter::MF' variable. llvm-svn: 94509
* Add support for target-specific 32-bit custom-lowered Chris Lattner2010-01-262-5/+8
| | | | | | jump table entries. llvm-svn: 94505
* switch jump table entry emission to be based on EntryKindChris Lattner2010-01-261-16/+39
| | | | | | instead of magic variables. llvm-svn: 94500
* Implement cond ? -1 : 0 with sbb.Evan Cheng2010-01-261-0/+8
| | | | llvm-svn: 94490
* Generate DEBUG_VALUE comments on x86. The (limited)Dale Johannesen2010-01-261-0/+3
| | | | | | | dbg.declare's we currently generate go through both register allocators without perturbing the results. llvm-svn: 94480
* Rearrange handling of jump tables. Highlights:Chris Lattner2010-01-256-65/+131
| | | | | | | | | | | | | | | | | | 1. MachineJumpTableInfo is now created lazily for a function the first time it actually makes a jump table instead of for every function. 2. The encoding of jump table entries is now described by the MachineJumpTableInfo::JTEntryKind enum. This enum is determined by the TLI::getJumpTableEncoding() hook, instead of by lots of code scattered throughout the compiler that "knows" that jump table entries are always 32-bits in pic mode (for example). 3. The size and alignment of jump table entries is now calculated based on their kind, instead of at machinefunction creation time. Future work includes using the EntryKind in more places in the compiler, eliminating other logic that "knows" the layout of jump tables in various situations. llvm-svn: 94470
* prep work to support a future where getJumpTableInfo will returnChris Lattner2010-01-251-3/+4
| | | | | | | a null pointer for functions with no jump tables. No functionality change. llvm-svn: 94469
* eliminate redundant argument to EmitJumpTableInfoChris Lattner2010-01-251-2/+3
| | | | llvm-svn: 94464
* mcstreamerize gprel32 emission.Chris Lattner2010-01-251-2/+3
| | | | llvm-svn: 94452
* mcize the non-gprel cases of AsmPrinter::printPICJumpTableEntryChris Lattner2010-01-251-13/+13
| | | | llvm-svn: 94450
* handle the _set_ symbol with an MCSymbol.Chris Lattner2010-01-251-5/+12
| | | | llvm-svn: 94449
* rename MAI::PICJumpTableDirective to MAI::GPRel32Directive toChris Lattner2010-01-251-9/+7
| | | | | | make it clear what it is, instead of how it is used. llvm-svn: 94448
* pull the non-pic jump table case out of printPICJumpTableEntryChris Lattner2010-01-251-10/+13
| | | | | | | and MCize the non-pic case. Now printPICJumpTableEntry really is just about printing PIC entries. llvm-svn: 94446
* remove JumpTableDirective, it is always null.Chris Lattner2010-01-251-1/+2
| | | | llvm-svn: 94445
* sink an arm specific method out of asmprinter into the ARMAsmPrinter andChris Lattner2010-01-251-13/+0
| | | | | | rename it to avoid shadowing. llvm-svn: 94440
* mcstreamerize .file and .file. This also fixes an issue where theChris Lattner2010-01-252-48/+8
| | | | | | | normal form of .file would fail if the filename had a weird character in it. llvm-svn: 94437
* emit ELF .type directives through MCStreamer instead of doing it textually.Chris Lattner2010-01-251-7/+2
| | | | llvm-svn: 94436
* add a commentChris Lattner2010-01-251-0/+1

* emit the .size directive for global variables on ELF throughChris Lattner2010-01-251-1/+1
| | | | | | mcstreamer. llvm-svn: 94416
* make -fno-rtti the default unless a directory builds with REQUIRES_RTTI.Chris Lattner2010-01-243-3/+0
| | | | llvm-svn: 94378
* fix some issues where we weren't emitting enough newlines.Chris Lattner2010-01-242-0/+3
| | | | llvm-svn: 94370
* when emitting DIEs, emit the comment on the same line as the directive.Chris Lattner2010-01-241-2/+3
| | | | | | This fixes FrontendObjC/2009-11-30-Objc-ID.m llvm-svn: 94369
* It seems better to scalarize vectors of size 1 instead of widening them.Mon P Wang2010-01-243-1/+11
| | | | | | Add support to widen SETCC. llvm-svn: 94342
* Improved widening loads by adding support for wider loads ifMon P Wang2010-01-243-275/+385
| | | | | | | the alignment allows. Fixed a bug where we didn't use a vector load/store for PR5626. llvm-svn: 94338
* Remove the '-disable-scheduling' flag and replace it with the 'source' option ofBill Wendling2010-01-234-690/+444
| | | | | | | | | the '-pre-RA-sched' flag. It actually makes more sense to do it this way. Also, keep track of the SDNode ordering by default. Eventually, we would like to make this ordering a way to break a "tie" in the scheduler. However, doing that now breaks the "CodeGen/X86/abi-isel.ll" test for 32-bit Linux. llvm-svn: 94308
* mcize lcomm, simplify .comm, extend both to support 64-bit sizes.Chris Lattner2010-01-231-2/+2
| | | | llvm-svn: 94299
* resolve a fixme: the "nonexecutable stack directive" is actuallyChris Lattner2010-01-231-5/+2
| | | | | | | | | 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
* remove a dead call.Chris Lattner2010-01-231-4/+0
| | | | llvm-svn: 94297
* mcize visibility directives.Chris Lattner2010-01-232-10/+17
| | | | llvm-svn: 94295
* move the various directive enums out of the MCStreamer classChris Lattner2010-01-232-16/+16
| | | | | | into a new MCDirectives.h file. llvm-svn: 94294
* Change constantexpr global variable initializers to convert the constantsChris Lattner2010-01-231-116/+71
| | | | | | | to MCExpr then emit them through MCStreamer with EmitValue. I think all global variable initializers are now going through mcstreamer. llvm-svn: 94293
* mcstreamerize .no_dead_strip and .reference for static ctors/dtors.Chris Lattner2010-01-233-21/+26
| | | | llvm-svn: 94290
* mcize jump table and constant pool entry labels, .local on elf,Chris Lattner2010-01-231-29/+45
| | | | | | and some .weak directives. llvm-svn: 94284
* emit .ascii and .asciz through MCStreamer.Chris Lattner2010-01-231-34/+12
