04b5d93250 ARM assembly shifts by zero should be plain 'mov' instructions.
"mov r1, r2, lsl #0" should assemble as "mov r1, r2" even though it's
not strictly legal UAL syntax. It's a common extension and the friendly
thing to do.

has no right hand side symbol.

a4e3c7fc4b ARM assembly parsing and encoding for VLD2 with writeback.
Refactor the instructions into fixed writeback and register-stride

the assembly parser to more easily handle these instructions.

Add tests for the instruction variants now supported.

e43862b6a6 ARM assembly parsing for register range syntax for VLD/VST register lists.
For example,
vld1.f64 {d2-d5}, [r2,:128]!

Should be equivalent to:
vld1.f64 {d2,d3,d4,d5}, [r2,:128]!

It's not documented syntax in the ARM ARM, but it is consistent with what's
accepted for VLDM/VSTM and is unambiguous in meaning, so it's a good thing to
support.

it is separating the directory part from the basename of the FileName.  Noticed 
that this:

  .file 1 "dir/foo"

when assembled got the two parts switched.  Using the Mac OS X dwarfdump tool
it can be seen easily:

% dwarfdump -a a.out
include_directories[  1] = 'foo'

When '~imm' is encodable as a t2_so_imm but plain 'imm' is not. For example,
  mov r2, #-3
becomes
  mvn r2, #2

5d0492cfc4 Thumb2 ADD/SUB instructions encoding selection outside IT block.
Outside an IT block, "add r3, #2" should select a 32-bit wide encoding
rather than generating an error indicating the 16-bit encoding is only
legal in an IT block (outside, the 'S' suffic is required for the 16-bit
encoding).

280dfad489 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.
