* [AVX] Make Inits FoldableDavid Greene2011-07-11
| | | | | | | | | | | | | | | | | | Manage Inits in a FoldingSet. This provides several benefits: - Memory for Inits is properly managed - Duplicate Inits are folded into Flyweights, saving memory - It enforces const-correctness, protecting against certain classes of bugs The above benefits allow Inits to be used in more contexts, which in turn provides more dynamism to TableGen. This enhanced capability will be used by the AVX code generator to a fold common patterns together. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134907 91177308-0d34-0410-b5e6-96231b3b80d8
* Resynchronize EDInfo.h and EDEmitter.cpp.Shantonu Sen2011-07-11
| | | | | | | | | | | | | The enum names as well as order (i.e. value) had skewed, which means that consumers of the tablegen-ed table would see different values than intended. Make both files have a superset of enums, and add classification as needed for numMCOperands.

| | | | | | | | | | | | | 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

* TableGen'erated MC lowering for simple pseudo-instructions.Jim Grosbach2011-07-08
| | | | | | | | | | | | | This allows the (many) pseudo-instructions we have that map onto a single real instruction to have their expansion during MC lowering handled automatically instead of the current cumbersome manual expansion required. These sorts of pseudos are common when an instruction is used in situations that require different MachineInstr flags (isTerminator, isBranch, et. al.) than the generic instruction description has. For example, using a move to the PC to implement a branch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134704 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

* Don't require pseudo-instructions to carry encoding information.Jim Grosbach2011-07-06
| | | | | | | | | | | | For now this is distinct from isCodeGenOnly, as code-gen-only instructions can (and often do) still have encoding information associated with them. Once we've migrated all of them over to true pseudo-instructions that are lowered to real instructions prior to the printer/emitter, we can remove isCodeGenOnly and just use isPseudo. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134539 91177308-0d34-0410-b5e6-96231b3b80d8

* Remove redundant Thumb2 ADD/SUB SP instruction definitions.Jim Grosbach2011-06-29
| | | | | | | | | | | | Unlike Thumb1, Thumb2 does not have dedicated encodings for adjusting the stack pointer. It can just use the normal add-register-immediate encoding since it can use all registers as a source, not just R0-R7. The extra instruction definitions are just duplicates of the normal instructions with the (not well enforced) constraint that the source register was SP. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134114 91177308-0d34-0410-b5e6-96231b3b80d8
