* Introduce MCCodeGenInfo, which keeps information that can affect codegenEvan Cheng2011-07-191-1/+18
| | | | | | | (including compilation, assembly). Move relocation model Reloc::Model from TargetMachine to MCCodeGenInfo so it's accessible even without TargetMachine. llvm-svn: 135468
* Sink getDwarfRegNum, getLLVMRegNum, getSEHRegNum from TargetRegisterInfo downEvan Cheng2011-07-181-1/+5
| | | | | | | | | to MCRegisterInfo. Also initialize the mapping at construction time. This patch eliminate TargetRegisterInfo from TargetAsmInfo. It's another step towards fixing the layering violation. llvm-svn: 135424

* It's not safe to fold (fptrunc (sqrt (fpext x))) to (sqrtf x) if there is ↵Evan Cheng2011-07-131-0/+2
| | | | | | another use of sqrt. rdar://9763193 llvm-svn: 135058
* Disassembler doesn't need TargetMachine anymore.Evan Cheng2011-07-111-17/+0
| | | | llvm-svn: 134920
* - Eliminate MCCodeEmitter's dependency on TargetMachine. It now uses MCInstrInfoEvan Cheng2011-07-111-2/+5
| | | | | | | | | | | | 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. llvm-svn: 134884
* Change createAsmParser to take a MCSubtargetInfo instead of triple,Evan Cheng2011-07-091-2/+6
| | | | | | | | | 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. llvm-svn: 134795
* Eliminate asm parser's dependency on TargetMachine:Evan Cheng2011-07-081-1/+2
| | | | | | | | | | - 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". llvm-svn: 134678
* createMCInstPrinter doesn't need TargetMachine anymore.Evan Cheng2011-07-061-2/+2
| | | | llvm-svn: 134525
* Fix the ridiculous SubtargetFeatures API where it implicitly expects CPU name toEvan Cheng2011-06-301-10/+2
| | | | | | | | | | be the first encoded as the first feature. It then uses the CPU name to look up features / scheduling itineray even though clients know full well the CPU name being used to query these properties. The fix is to just have the clients explictly pass the CPU name! llvm-svn: 134127
* Sink SubtargetFeature and TargetInstrItineraries (renamed ↵Evan Cheng2011-06-291-1/+1
| | | | | | MCInstrItineraries) into MC. llvm-svn: 134049
* Use the verbose asm flag instead of a new flag for decoding the LSDA.Bill Wendling2011-06-171-6/+1
| | | | llvm-svn: 133292
* Add an option that allows one to "decode" the LSDA.Bill Wendling2011-06-171-6/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The LSDA is a bit difficult for the non-initiated to read. Even with comments, it's not always clear what's going on. This wraps the ASM streamer in a class that retains the LSDA and then emits a human-readable description of what's going on in it. So instead of having to make sense of: Lexception1: .byte 255 .byte 155 .byte 168 .space 1 .byte 3 .byte 26 Lset0 = Ltmp7-Leh_func_begin1 .long Lset0 Lset1 = Ltmp812-Ltmp7 .long Lset1 Lset2 = Ltmp913-Leh_func_begin1 .long Lset2 .byte 3 Lset3 = Ltmp812-Leh_func_begin1 .long Lset3 Lset4 = Leh_func_end1-Ltmp812 .long Lset4 .long 0 .byte 0 .byte 1 .byte 0 .byte 2 .byte 125 .long __ZTIi@GOTPCREL+4 .long __ZTIPKc@GOTPCREL+4 you can read this instead: ## Exception Handling Table: Lexception1 ## @LPStart Encoding: omit ## @TType Encoding: indirect pcrel sdata4 ## @TType Base: 40 bytes ## @CallSite Encoding: udata4 ## @Action Table Size: 26 bytes ## Action 1: ## A throw between Ltmp7 and Ltmp812 jumps to Ltmp913 on an exception. ## For type(s): __ZTIi@GOTPCREL+4 __ZTIPKc@GOTPCREL+4 ## Action 2: ## A throw between Ltmp812 and Leh_func_end1 does not have a landing pad. llvm-svn: 133286

* We need to pass the TargetMachine object to the InstPrinter if we are printingBill Wendling2011-03-211-4/+26
| | | | | | | | | the alias of an InstAlias instead of the thing being aliased. Because we need to know the features that are valid for an InstAlias. This is part of a work-in-progress. llvm-svn: 127986

* Make tool_output_file's raw_ostream instance a member variable insteadDan Gohman2010-09-011-43/+43
| | | | | | | | | | of a base class. This makes it possible to unregister the file from FilesToRemove when the file is done. Also, this eliminates the need for formatted_tool_output_file. llvm-svn: 112706

* Use the new tool_output_file in several tools. This fixes a varietyDan Gohman2010-08-201-64/+76
| | | | | | | | of problems with output files being left behind or output streams being left unclosed. Fix llvm-mc to respect the -o option in all modes, rather than hardcoding outs() in some cases. llvm-svn: 111603
* llvm-mc: Add -show-inst-operands, for dumping the parsed instruction ↵Daniel Dunbar2010-08-111-0/+5
| | | | | | representation before matching. llvm-svn: 110791
* Plug the remaining MC leaks by giving MCObjectStreamer/MCAsmStreamer ↵Benjamin Kramer2010-07-291-7/+6

* Target: Give the TargetAsmParser access to the TargetMachine.Daniel Dunbar2010-07-191-1/+1
| | | | | | - Unfortunate, but necessary for now to handle subtarget instruction matching. Eventually we should factor out the lower level target machine information so we don't need to do this. llvm-svn: 108664

* Avoid calling outs() and fouts() when the stream isn't really needed.Dan Gohman2010-05-271-2/+1

* MC: Add an MCLoggingStreamer, for use in debugging integrated-as mismatches.Daniel Dunbar2010-05-231-0/+7
| | | | llvm-svn: 104463
* Currently, createMachOStreamer() is invoked directly in llvm-mc whichMatt Fleming2010-05-211-1/+2
| | | | | | | | | isn't ideal if we want to be able to use another object file format. Add a createObjectStreamer() factory method so that the correct object file streamer can be instantiated for a given target triple. llvm-svn: 104318

| | | | | | | | | | | time I use the LIBS variable, which is not subject to a %.a -> -l% transformation, to link llvm-mc against libEnhancedDisassembly. llvm-mc -edis works the same as llvm-mc -disassemble, but outputs tokens and operands. llvm-svn: 101058
