[ARM] Disassembles SSAT and SSAT16 instructions incorrectly for Thumb-2
2015-04-15 Renlin Li <renlin.li@arm.com>
opcodes/:
* arm-dis.c (thumb32_opcodes): Define 'D' format control code,
use it for ssat and ssat16.
(print_insn_thumb32): Add handle case for 'D' control code.
gas/testsuite/:
* gas/arm/arch7em.d: Adjust required ssat and ssat16 immediate field.
* gas/arm/thumb32.d: Likewise.
