* - Eliminate MCCodeEmitter's dependency on TargetMachine. It now uses MCInstrInfoEvan Cheng2011-07-111-21/+24
| | | | | | | | | | | | | 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

| | | | | | | | | | | The reg-reg copies were no longer being generated since copyPhysReg copies physical registers only. The loads and stores are not necessary - The TC constraint is imposed by the TAILJMP and TCRETURN instructions, there should be no need for constrained loads and stores. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@116314 91177308-0d34-0410-b5e6-96231b3b80d8

* Start the support for AVX instructions with 256-bit %ymm registers. A couple ofBruno Cardoso Lopes2010-07-091-1/+11
| | | | | | | | | | | | | | | | | notes: - The instructions are being added with dummy placeholder patterns using some 256 specifiers, this is not meant to work now, but since there are some multiclasses generic enough to accept them, when we go for codegen, the stuff will be already there. - Add VEX encoding bits to support YMM - Add MOVUPS and MOVAPS in the first round - Use "Y" as suffix for those Instructions: MOVUPSYrr, ... - All AVX instructions in X86InstrSSE.td will move soon to a new X86InstrAVX file. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107996 91177308-0d34-0410-b5e6-96231b3b80d8
