* Move global variables in TargetMachine into new TargetOptions class. As an APINick Lewycky2011-12-021-4/+7
| | | | | | | | | | | | change, now you need a TargetOptions object to create a TargetMachine. Clang patch to follow. One small functionality change in PTX. PTX had commented out the machine verifier parts in their copy of printAndVerify. That now calls the version in LLVMTargetMachine. Users of PTX who need verification disabled should rely on not passing the command-line flag to enable it. llvm-svn: 145714
* Sink codegen optimization level into MCCodeGenInfo along side relocation modelEvan Cheng2011-11-161-10/+10
| | | | | | | and code model. This eliminates the need to pass OptLevel flag all over the place and makes it possible for any codegen pass to use this information. llvm-svn: 144788
* Move TargetRegistry and TargetSelect from Target to Support where they belong.Evan Cheng2011-08-241-1/+1
| | | | | | These are strictly utilities for registering targets and components. llvm-svn: 138450
* Refactor PPC target to separate MC routines from Target routines.Evan Cheng2011-07-251-26/+0
| | | | llvm-svn: 135942
* - Move CodeModel from a TargetMachine global option to MCCodeGenInfo.Evan Cheng2011-07-201-8/+9
| | | | | | | | - 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
* Introduce MCCodeGenInfo, which keeps information that can affect codegenEvan Cheng2011-07-191-29/+13
| | | | | | | (including compilation, assembly). Move relocation model Reloc::Model from TargetMachine to MCCodeGenInfo so it's accessible even without TargetMachine. llvm-svn: 135468
* Rename createAsmInfo to createMCAsmInfo and move registration code to ↵Evan Cheng2011-07-141-13/+0
| | | | | | MCTargetDesc to prepare for next round of changes. llvm-svn: 135219
* Eliminate asm parser's dependency on TargetMachine:Evan Cheng2011-07-081-1/+1
| | | | | | | | | | - 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
* Fix the ridiculous SubtargetFeatures API where it implicitly expects CPU name toEvan Cheng2011-06-301-3/+6
| | | | | | | | | | 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
* ADT/Triple: Move a variety of clients to using isOSDarwin() and isOSWindows()Daniel Dunbar2011-04-191-6/+4
| | | | | | predicates. llvm-svn: 129816
* Add support for the --noexecstack option.Rafael Espindola2011-01-231-1/+2
| | | | llvm-svn: 124077
* Rename TargetFrameInfo into TargetFrameLowering. Also, put couple of FIXMEs ↵Anton Korobeynikov2011-01-101-1/+1
| | | | | | and fixes here and there. llvm-svn: 123170
* Wire up primitive support in the assembler backend for writing .o filesChris Lattner2010-11-151-0/+24
| | | | | | | | | | | | | | directly on the mac. This is very early, doesn't support relocations and has a terrible hack to avoid .machine from being printed, but despite that it generates an bitwise-identical-to-cctools .o file for stuff like this: define i32 @test() nounwind { ret i32 42 } I don't plan to continue pushing this forward, but if anyone else was interested in doing it, it should be really straight-forward. llvm-svn: 119136
* Implement a basic MCCodeEmitter for PPC. This doesn't handleChris Lattner2010-11-151-0/+4
| | | | | | | | | | | | | | | | fixups yet, and doesn't handle actually encoding operand values, but this is enough for llc -show-mc-encoding to show the base instruction encoding information, e.g.: mflr r0 ; encoding: [0x7c,0x08,0x02,0xa6] stw r0, 8(r1) ; encoding: [0x90,0x00,0x00,0x00] stwu r1, -64(r1) ; encoding: [0x94,0x00,0x00,0x00] Ltmp0: lhz r4, 4(r3) ; encoding: [0xa0,0x00,0x00,0x00] cmplwi cr0, r4, 8 ; encoding: [0x28,0x00,0x00,0x00] beq cr0, LBB0_2 ; encoding: [0x40,0x00,0x00,0x00] llvm-svn: 119116

* Implement a bunch more TargetSelectionDAGInfo infrastructure.Dan Gohman2010-05-111-1/+2
| | | | | | | | Move EmitTargetCodeForMemcpy, EmitTargetCodeForMemset, and EmitTargetCodeForMemmove out of TargetLowering and into SelectionDAGInfo to exercise this. llvm-svn: 103481
* TargetRegistry: Fix create{AsmInfo,MCDisassembler} to return non-const objects.Daniel Dunbar2010-03-201-1/+1

| | | | | | Personality / FDE / LSDA / TType encoding depending on target / options (e.g. code model / relocation model) - MCIzation of Dwarf EH printer to use encoding information - Stub generation for ELF target (needed for indirect references) - Some other small changes here and there llvm-svn: 96285
