2011-07-14Next round of MC refactoring. This patch factor MC table instantiations, MCEvan Cheng
registeration and creation code into XXXMCDesc libraries. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135184 91177308-0d34-0410-b5e6-96231b3b80d8
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
2011-07-08Eliminate 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

2011-07-01- Added MCSubtargetInfo to capture subtarget features and schedulingEvan Cheng
itineraries. - Refactor TargetSubtarget to be based on MCSubtargetInfo. - Change tablegen generated subtarget info to initialize MCSubtargetInfo and hide more details from targets. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134257 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-30Fix the ridiculous SubtargetFeatures API where it implicitly expects CPU name toEvan Cheng
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

2011-04-15Increase SubtargetFeatureKV Value and Implies fields to 64 bits since some ↵Evan Cheng
targets are getting very close to 32 subtarget features. Also teach tablegen to error when there are more than 64 features to guard against undefined behavior. rdar://9282332 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129590 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-09For each instruction itinerary class, specify the number of micro-ops eachEvan Cheng
instruction in the class would be decoded to. Or zero if the number of uOPs must be determined dynamically.

2009-08-17Extend the instruction itinerary model to include the ability to indicate ↵David Goodwin

2008-09-11lib/Target/SubtargetFeature.cpp asserts that the FeatureKV[] table be sorted Jim Grosbach
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

2008-02-14Rewrite tblgen handling of subtarget features soDale Johannesen
it follows the order of the enum, not alphabetical. The motivation is to make -mattr=+ssse3,+sse41 select SSE41 as it ought to.

2007-05-04Add an "implies" field to features. This indicates that, if the currentBill Wendling
feature is set, then the features in the implied list should be set also. The opposite is also enforced: if a feature in the implied list isn't set, then the feature that owns that implies list shouldn't be set either. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@36756 91177308-0d34-0410-b5e6-96231b3b80d8
