* Allow MCCodeEmitter access to the target MCRegisterInfo.Jim Grosbach2012-05-151-2/+2
| | | | | | | | Add the MCRegisterInfo to the factories and constructors. Patch by Tom Stellard <Tom.Stellard@amd.com>. llvm-svn: 156828
* Fix it so llvm-objdump -arch does accept x86 and x86-64 as valid arch names.Kevin Enderby2012-05-081-30/+8
| | | | | | PR12731. Patch by Meador Inge! llvm-svn: 156444
* Add -disassemble support for -show-inst and -show-encode capability llvm-mc. ↵Richard Barton2012-04-161-116/+56
| | | | | | | | Also refactor so all MC paraphernalia are created once for all uses as much as possible. The test change is to account for the fact that the default disassembler behaviour has changed with regards to specifying the assembly syntax to use. llvm-svn: 154809
* Make member variables of AsmToken private. Remove unnecessary forward ↵Craig Topper2012-04-151-0/+1
| | | | | | declarations. Remove an unnecessary include. llvm-svn: 154775
* Make MCInstrInfo available to the MCInstPrinter. This will be used to remove ↵Craig Topper2012-04-021-1/+1
| | | | | | getInstructionName and the static data it contains since the same tables are already in MCInstrInfo. llvm-svn: 153860
* Have llvm-mc --version print the list of registered targets like llc does.Duncan Sands2012-03-081-0/+3
| | | | | | Patch by jey. llvm-svn: 152315
* Make MCRegisterInfo available to the the MCInstPrinter.Jim Grosbach2012-03-051-1/+1
| | | | | | | Used to allow context sensitive printing of super-register or sub-register references. llvm-svn: 152043
* llvm-mc pass through SourceMgr to MCContext.Jim Grosbach2012-01-261-1/+1
| | | | llvm-svn: 149091
* Remove unreachable code. (replace with llvm_unreachable to help GCC where ↵David Blaikie2012-01-171-2/+0
| | | | | | necessary) llvm-svn: 148284
* Remove unnecessary default cases in switches that cover all enum values.David Blaikie2012-01-101-1/+0
| | | | llvm-svn: 147855
* Remove the logging streamer.Rafael Espindola2012-01-101-7/+0
| | | | llvm-svn: 147820
* The second part of support for generating dwarf for assembly source files. ThisKevin Enderby2011-12-091-0/+14
| | | | | | | | | | generates the dwarf Compile Unit DIE and a dwarf subprogram DIE for each non-temporary label. The next part will be to get the clang driver to enable this when assembling a .s file. rdar://9275556 llvm-svn: 146262
* Tidy up.Jim Grosbach2011-12-051-1/+1
| | | | llvm-svn: 145870
* First part of support for generating dwarf for assembly source files with theKevin Enderby2011-11-011-0/+6
| | | | | | | | | | | | -g flag. In this part we generate the .file for the source being assembled and the .loc's for the assembled instructions. The next part will be to generate the dwarf Compile Unit DIE and a dwarf subprogram DIE for each non-temporary label. Once the next part is done test cases will be added. rdar://9275556 llvm-svn: 143509
* rename getHostTriple into getDefaultTargetTripleSebastian Pop2011-11-011-1/+1
| | | | llvm-svn: 143502
* Add support for a new extension to the .file directive:Nick Lewycky2011-10-171-3/+4
| | | | | | | | | | .file filenumber "directory" "filename" This removes one join+split of the directory+filename in MC internals. Because bitcode files have independent fields for directory and filenames in debug info, this patch may change the .o files written by existing .bc files. llvm-svn: 142300
* Make SMDiagnostic a little more sane. Instead of passing around ↵Chris Lattner2011-10-161-1/+2
| | | | | | | | note/warning/error as a string, pass it around as an enum. llvm-svn: 142107
* Refactor instprinter and mcdisassembler to take a SubtargetInfo. Add -mattr= ↵James Molloy2011-09-071-5/+26
| | | | | | handling to llvm-mc. Reviewed by Owen Anderson. llvm-svn: 139237
* Move TargetRegistry and TargetSelect from Target to Support where they belong.Evan Cheng2011-08-241-2/+2
| | | | | | These are strictly utilities for registering targets and components. llvm-svn: 138450
* Remove unused Target argument from AsmParser construction methods.Jim Grosbach2011-08-161-2/+2
| | | | | | The argument is unused, and is a layering violation in any case. llvm-svn: 137735
* Fix llvm-mc target detection code to match llc.Evan Cheng2011-07-261-12/+33

* Rename TargetAsmParser to MCTargetAsmParser and TargetAsmLexer to ↵Evan Cheng2011-07-261-2/+2
| | | | | | MCTargetAsmLexer; rename createAsmLexer to createMCAsmLexer and createAsmParser to createMCAsmParser. llvm-svn: 136027

* Separate MCInstPrinter registration from AsmPrinter registration.Evan Cheng2011-07-251-5/+0
| | | | llvm-svn: 135974
* Fix last bits of MC layer issues. llvm-mc doesn't need to initialize ↵Evan Cheng2011-07-251-3/+0
| | | | | | TargetMachine's anymore. llvm-svn: 135963
* Move TargetAsmParser.h TargetAsmBackend.h and TargetAsmLexer.h to MC where ↵Evan Cheng2011-07-231-2/+2
| | | | | | they belong. llvm-svn: 135833
* Combine all MC initialization routines into one. e.g. InitializeX86MCAsmInfo,Evan Cheng2011-07-221-5/+1
| | | | | | InitializeX86MCInstrInfo, etc. are combined into InitializeX86TargetMC. llvm-svn: 135812
* Move the registered target printing in version strings completely out ofChandler Carruth2011-07-221-0/+4
| | | | | | | | | | | | | | | | | the Support library. Now its part of the TargetRegistry, and the three commands that care about this explicitly register this extra bit of version information. The set of commands which care was computed by intersecting those which use the Support library's version string printing and those that initialize all the registered targets in a way that produces a meaningful list. The only odd ball out is that 'clang -cc1as -version' no longer prints the registered targets. I don't think anyone is really interested in that (especially as the fact that llvm-mc does so is under a FIXME), but if someone really does want this back I'll happily apply the same patch there. llvm-svn: 135757
* Goodbye TargetAsmInfo. This eliminate last bit of CodeGen and Target in llvm-mc.Evan Cheng2011-07-201-27/+2
| | | | | | | There is still a bit more refactoring left to do in Targets. But we are now very close to fixing all the layering issues in MC. llvm-svn: 135611
* - Move CodeModel from a TargetMachine global option to MCCodeGenInfo.Evan Cheng2011-07-201-1/+18
| | | | | | | | - Introduce JITDefault code model. This tells targets to set different default code model for JIT. This eliminates the ugly hack in TargetMachine where code model is changed after construction. llvm-svn: 135580
* Add MCObjectFileInfo and sink the MCSections initialization code fromEvan Cheng2011-07-201-1/+8
| | | | | | | | TargetLoweringObjectFileImpl down to MCObjectFileInfo. TargetAsmInfo is done to one last method. It's *almost* gone! llvm-svn: 135569
* 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

* - 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

* 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

* 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
