Owen Anderson c7baee31ad Add support for ARM's specialized vector-compare-against-zero instructions. 
llvm-svn: 118453
 2010-11-08 23:21:22 +00:00
Owen Anderson 30c4892ea5 Add codegen and encoding support for the immediate form of vbic.

 2010-11-05 19:27:46 +00:00
Owen Anderson 0747307049 Add support for code generation of the one register with immediate form of vorr. 
We could be more aggressive about making this work for a larger range of constants,
but this seems like a good start.

Owen Anderson bb81f80af6 Unlike a lot of NEON instructions, vext isn't _actually_ parameterized by element size. Instead, 
all of the different element sizes are pseudo instructions that map down to vext.8 underneath, with
the immediate shifted left to reflect the increased element size.

Jim Grosbach c6af2b4066 Break ARM addrmode4 (load/store multiple base address) into its constituent 
parts. Represent the operation mode as an optional operand instead.

Owen Anderson 9e44cf2bb2 ARM encodes Q registers as 2xregno (i.e. the number of the D register that corresponds to the lower 
half of the Q register), rather than with just regno.  This allows us to unify the encodings for
a lot of different NEON instrucitons that differ only in whether they have Q or D register operands.
