2011-07-19Use the CompactUnwindEncoding from the Frame, if it's defined.Bill Wendling
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135451 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-19Add a method to set compact unwind encoding information in a frame.Bill Wendling
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135449 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-19Fixed a bug where the MC subtarget informationSean Callanan
wasn't being initialized by the enhanced disassembler, leading to assertion failures. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135447 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-18Move getInitialFrameState from TargetFrameInfo to MCAsmInfo (suggestions forEvan Cheng
better location welcome). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135438 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-18Sink getDwarfRegNum, getLLVMRegNum, getSEHRegNum from TargetRegisterInfo downEvan Cheng
to MCRegisterInfo. Also initialize the mapping at construction time. This patch eliminate TargetRegisterInfo from TargetAsmInfo. It's another step towards fixing the layering violation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135424 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-15Move some parts of TargetAsmInfo down to MCAsmInfo. This is not the greatestEvan Cheng
solution but it is a small step towards removing the horror that is TargetAsmInfo. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135237 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-14* If we have an LSDA, we need to mark it in the encoding.Bill Wendling

2011-07-14Unfortunately several files in MC are badly violating layering rule by usingEvan Cheng
TargetAsmInfo, which in turn pulls in TargetRegisterInfo, etc. :-( There are other cases of violations, but this is probably the worst. This patch is but one small step towards fixing this. 500 more steps to go. :-( git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135131 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-13Update MCParsedAsmOperand debug methods.Jim Grosbach
Update the debug output interface for MCParsedAsmOperand to have a print() method which takes an output stream argument, an << operator which invokes the print method using the given stream, and a dump() method which prints the operand to the dbgs() stream. This makes the interface more consistent with the rest of LLVM, and more convenient to use at the debugger command line. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135043 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-11Resynchronize EDInfo.h and EDEmitter.cpp.Shantonu Sen
The enum names as well as order (i.e. value) had skewed, which means that consumers of the tablegen-ed table would see different values than intended. Make both files have a superset of enums, and add classification as needed for numMCOperands.

2011-07-11- Eliminate MCCodeEmitter's dependency on TargetMachine. It now uses MCInstrInfoEvan Cheng
and MCSubtargetInfo. - Added methods to update subtarget features (used when targets automatically detect subtarget features or switch modes). - Teach X86Subtarget to update MCSubtargetInfo features bits since the MCSubtargetInfo layer can be shared with other modules. - These fixes .code 16 / .code 32 support since mode switch is updated in MCSubtargetInfo so MC code emitter can do the right thing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134884 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-09Change createAsmParser to take a MCSubtargetInfo instead of triple,Evan Cheng
CPU, and feature string. Parsing some asm directives can change subtarget state (e.g. .code 16) and it must be reflected in other modules (e.g. MCCodeEmitter). That is, the MCSubtargetInfo instance must be shared. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134795 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-08Eliminate asm parser's dependency on TargetMachine:Evan Cheng
- Each target asm parser now creates its own MCSubtatgetInfo (if needed). - Changed AssemblerPredicate to take subtarget features which tablegen uses to generate asm matcher subtarget feature queries. e.g. "ModeThumb,FeatureThumb2" is translated to "(Bits & ModeThumb) != 0 && (Bits & FeatureThumb2) != 0". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134678 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-07This patch adds a flag in MCAsmInfo that indicates whether dwarf registerAkira Hatanaka
numbers should be printed instead of symbolic register names in MCAsmStreamer::EmitRegisterName. This is necessary because some versions of GNU assembler won't accept code in which symbolic register names are used in cfi directives. There is no change in behavior unless the flag is explicitly set to true by a backend. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134635 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-30Fix the ridiculous SubtargetFeatures API where it implicitly expects CPU name toEvan Cheng
