Jim Grosbach 3ea0657d54 ARM assembly parsing and encoding for VLD1 w/ writeback. 
One and two length register list variants.

Jim Grosbach 2098cb1e6f ARM refactor am6offset usage for VLD1. 
Split am6offset into fixed and register offset variants so the instruction
encodings are explicit rather than relying an a magic reg0 marker.
Needed to being able to parse these.

Jim Grosbach 2f2e3c4737 ARM VLD parsing and encoding. 
Next step in the ongoing saga of NEON load/store assmebly parsing. Handle
VLD1 instructions that take a two-register register list.

Adjust the instruction definitions to only have the single encoded register
as an operand. The super-register from the pseudo is kept as an implicit def,
so passes which come after pseudo-expansion still know that the instruction
defines the other subregs.

Jim Grosbach 741cd73aab ARM NEON "vmov.i8" immediate assembly parsing and encoding. 
NEON immediates are "interesting". Start of the work to handle parsing them
in an 'as' compatible manner. Getting the matcher to play nicely with
these and the floating point immediates from VFP is an extra fun wrinkle.

Owen Anderson e0152a73c2 Replace the existing ARM disassembler with a new one based on the FixedLenDecoderEmitter. 
This new disassembler can correctly decode all the testcases that the old one did, though
some "expected failure" testcases are XFAIL'd for now because it is not (yet) as strict in
operand checking as the old one was.

Bill Wendling 3b1459b810 Narrow right shifts need to encode their immediates differently from a normal 
shift.

   16-bit: imm6<5:3> = '001', 8 - <imm> is encded in imm6<2:0>
   32-bit: imm6<5:4> = '01',16 - <imm> is encded in imm6<3:0>

llvm-svn: 126477
 2011-02-25 06:42:42 +00:00
Bob Wilson a609b8954e Change VLD3/4 and VST3/4 for quad registers to not update the address register. 
These operations are expanded to pairs of loads or stores, and the first one
uses the address register update to produce the address for the second one.
So far, the second load/store has also updated the address register, just
for convenience, since that output has never been used.  In anticipation of
actually supporting post-increment updates for these operations, this changes
the non-updating operations to use a non-updating load/store for the second
instruction.
