2010-03-14change the LabelSDNode to be EHLabelSDNode and make it holdChris Lattner
an MCSymbol. Make the EH_LABEL MachineInstr hold its label with an MCSymbol instead of ID. Fix a bug in MMI.cpp which would return labels named "Label4" instead of "label4". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98463 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-14change EH related stuff (other than EH_LABEL) to use MCSymbolChris Lattner
instead of label ID's. This cleans up and regularizes a bunch of code and makes way for future progress. Unfortunately, this pointed out to me that JITDwarfEmitter.cpp is largely copy and paste from DwarfException/MachineModuleInfo and other places. This is very sad and disturbing. :( One major change here is that TidyLandingPads moved from being called in DwarfException::BeginFunction to being called in DwarfException::EndFunction. There should not be any functionality change from doing this, but I'm not an EH expert. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98459 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

2010-03-12The same situation that effected ARM effects PPC with regards to placing theBill Wendling
LSDA into the TEXT section. We need to generate non-lazy pointers to it on Mach-O. However, the object the NLP points to may be local to the translation unit. If so, then the NLP needs to have the value of that object specified instead of "0", which the linker interprets as "external". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98325 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-10Add a bit along with the MCSymbols stored in the MachineModuleInfo maps thatBill Wendling
indicates that an MCSymbol is external or not. (It's true if it's external.) This will be used to specify the correct information to add to non-lazy pointers. That will be explained further when this bit is used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98199 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-09Change the Value argument to eliminateFrameIndex to a type-tagged value. ThisJim Grosbach

2010-02-27remove a bogus pattern, which had the same pattern as STDUChris Lattner
but codegen'd differently. This really wanted to use some sort of subreg to get the low 4 bytes of the G8RC register or something. However, it's invalid and nothing is testing it, so I'm just zapping the bogosity. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97345 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-26Merge PPC instructions FMRS and FMRD into a single FMR instruction.Jakob Stoklund Olesen
This is possible because F8RC is a subclass of F4RC. We keep FMRSD around so fextend has a pattern. Also allow folding of memory operands on FMRSD. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97275 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-26Use the right floating point load/store instructions in ↵Jakob Stoklund Olesen
PPCInstrInfo::foldMemoryOperandImpl(). The PowerPC floating point registers can represent both f32 and f64 via the two register classes F4RC and F8RC. F8RC is considered a subclass of F4RC to allow cross-class coalescing. This coalescing only affects whether registers are spilled as f32 or f64. Spill slots must be accessed with load/store instructions corresponding to the class of the spilled register. PPCInstrInfo::foldMemoryOperandImpl was looking at the instruction opcode which is wrong. X86 has similar floating point register classes, but doesn't try to fold memory operands, so there is no problem there. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97262 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-12When save/restoring CR at prolog/epilog, in a largeDale Johannesen
stack frame, the prolog/epilog code was using the same register for the copy of CR and the address of the save slot. Oops. This is fixed here for Darwin, sort of, by reserving R2 for this case. A better way would be to do the store before the decrement of SP, which is safe on Darwin due to the red zone. SVR4 probably has the same problem, but I don't know how to fix it; there is no red zone and R2 is already used for something else. I'm going to leave it to someone interested in that target. Better still would be to rewrite the CR-saving code completely; spilling each CR subregister individually is horrible code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96015 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-27Kill ModuleProvider and ghost linkage by inverting the relationship betweenJeffrey Yasskin
Modules and ModuleProviders. Because the "ModuleProvider" simply materializes GlobalValues now, and doesn't provide modules, it's renamed to "GVMaterializer". Code that used to need a ModuleProvider to materialize Functions can now materialize the Functions directly. Functions no longer use a magic linkage to record that they're materializable; they simply ask the GVMaterializer. Because the C ABI must never change, we can't remove LLVMModuleProviderRef or the functions that refer to it. Instead, because Module now exposes the same functionality ModuleProvider used to, we store a Module* in any LLVMModuleProviderRef and translate in the wrapper methods. The bindings to other languages still use the ModuleProvider concept. It would probably be worth some time to update them to follow the C++ more closely, but I don't intend to do it.
