2011-07-25- Handle special scalar_to_vector case: splats. Using a native 128-bitBruno Cardoso Lopes
shuffle before inserting on a 256-bit vector. - Add AVX versions of movd/movq instructions - Introduce a few COPY patterns to match insert_subvector instructions. This turns a trivial insert_subvector instruction into a register copy, coalescing the xmm into a ymm and avoid emiting on more instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136002 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-25ARM assembly parsing and encoding for SSAT instruction.Jim Grosbach
Fix the Rn register encoding for both SSAT and USAT. Update the parsing of the shift operand to correctly handle the allowed shift types and immediate ranges and issue meaningful diagnostics when an illegal value or shift type is specified. Add aliases to parse an ommitted shift operand (default value of 'lsl #0'). Add tests for diagnostics and proper encoding. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135990 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-25Check in updated CMake dependencies after Evan's latest round ofChandler Carruth
refactorings. Several places that shouldn't have dependend on Target no longer do. Also almost all of the CodeGen dependencies have gone away for the MCDisassembler.

assert-path code, as previously we would have fallen off the end of the function, but please review and let me know if this should go somewhere else.
