Jim Grosbach 475c6dbef6 ARM assembly parsing and encoding for SSAT16 instruction.

Bruno Cardoso Lopes 9212bf275d Codegen allonesvector better while using AVX: vpcmpeqd + vinsertf128 
This also fixes PR10452

Bruno Cardoso Lopes ec21941de0 Add remaining 256-bit vector bitcasts. This also fixes PR10451 
llvm-svn: 136003
 2011-07-25 23:05:28 +00:00
Bruno Cardoso Lopes 123dff0f58 - Handle special scalar_to_vector case: splats. Using a native 128-bit 
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.

Bruno Cardoso Lopes 276eb8debf Reintroduce r135730, this is indeed the right approach, there is no 
native 256-bit vector instruction to do scalar_to_vector.

Jim Grosbach 3a9cbeed73 ARM assembly parsing and encoding for SSAT instruction. 
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.

Eli Friedman ea8c66fea5 Get rid of an incorrect optimization for shuffles with PALIGNR and simplify isPALIGNRMask. 
Addresses PR10466, although the crash from that PR only triggers in cases where DAGCombine misses optimizing a shuffle.

Chandler Carruth e0e91c6d30 Check in updated CMake dependencies after Evan's latest round of 
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. Others add reasonable dependencies within the
target-specific layers.

Chandler Carruth b2561029b1 Add a missing enumerator to this switch. Currently its in the 
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.

This fixes a Clang warning:
lib/MC/MCMachOStreamer.cpp:201:11: error: enumeration value 'MCSA_IndirectSymbol' not handled in switch [-Werror,-Wswitch-enum]
  switch (Attribute) {
          ^

Jim Grosbach 3ddf6aa503 Simply ARM so_reg MIOperandInfo definitions. 
The shift immediate encoding, printing, etc. is handled directly by the
enclosing operand definition, so it should be a vanilla immediate, not a
nested complex operand (shift_imm).
