Jim Grosbach 03f56d9de6 ARM parsing and encoding of SBFX and UBFX. 
Encode the width operand as it encodes in the instruction, which simplifies
the disassembler and the encoder, by using the imm1_32 operand def. Add a
diagnostic for the context-sensitive constraint that the width must be in
the range [1,32-lsb].

Jim Grosbach 38b5503d21 ARM cleanup of remaining extend instructions. 
Refactor the rest of the extend instructions to not artificially distinguish
between a rotate of zero and a rotate of any other value. Replace the by-zero
versions with Pat<>'s for ISel.

Jim Grosbach 8b31ef50c0 ARM extend instructions simplification. 
Refactor the SXTB, SXTH, SXTB16, UXTB, UXTH, and UXTB16 instructions to not
have an 'r' and an 'r_rot' version, but just a single version with a rotate
that can be zero. Use plain Pat<>'s for the ISel of the non-rotated version.

Bruno Cardoso Lopes f9324f4f6b Move some code around to open opportunity for more shuffle matching 
llvm-svn: 136201
 2011-07-27 00:56:37 +00:00
Bruno Cardoso Lopes 27a30a7792 The vpermilps and vpermilpd have different behaviour regarding the 
usage of the shuffle bitmask. Both work in 128-bit lanes without
crossing, but in the former the mask of the high part is the same
used by the low part while in the later both lanes have independent
masks. Handle this properly and and add support for vpermilpd.

Devang Patel f098ce2757 It is quiet possible that inlined function body is split into multiple chunks of consequtive instructions. But, there is not any way to describe this in .debug_inline accelerator table used by gdb. However, describe non contiguous ranges of inlined function body appropriately using AT_range of DW_TAG_inlined_subroutine debug info entry.
