* Eliminate "const" from extern const to fix breakeage since r135184 on msvc.NAKAMURA Takumi2011-07-15
| | | | | | MSVC decorates (and distinguishes) "const" in mangler. It brought linkage error between "extern const" declarations and definitions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135269 91177308-0d34-0410-b5e6-96231b3b80d8

* - Eliminate MCCodeEmitter's dependency on TargetMachine. It now uses MCInstrInfoEvan Cheng2011-07-11
| | | | | | | | | | | | | 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
* Eliminate asm parser's dependency on TargetMachine:Evan Cheng2011-07-08
| | | | | | | | | | | - 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

* Fix the ridiculous SubtargetFeatures API where it implicitly expects CPU name toEvan Cheng2011-06-30
| | | | | | | | | | | 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! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134127 91177308-0d34-0410-b5e6-96231b3b80d8

* lib/Target/SubtargetFeature.cpp asserts that the FeatureKV[] table be sorted Jim Grosbach2008-09-11
| | | | | | | | | | | | by its first field, but TableGen doesn't actually enforce creating it that way. TableGen sorts the records that will be used to create it by the names of the records, not the Name field of those records. This patch corrects the sort to use the "Name" field of the record as the sort key. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56106 91177308-0d34-0410-b5e6-96231b3b80d8

* Add an "implies" field to features. This indicates that, if the currentBill Wendling2007-05-04
