Log message:
Correctly consume mandatory 0x66 prefix when disassembling
aes{dec{,last},enc{,last},imc} instructions (regression in 2.17).
Correctly disassemble aeskeygenassist.
Before (binutils 2.15):
0: 66 0f 38 db c8 aesimc %xmm0,%xmm1
5: 66 0f 3a 44 da 04 pclmulqdq $0x4,%xmm2,%xmm3
b: 66 0f 3a 44 ec 10 pclmullqhqdq %xmm4,%xmm5
11: 66 data16
12: 0f .byte 0xf
13: 3a df cmp %bh,%bl
15: fe 08 decb (%rax)
Currently (binutils 2.17):
0: 66 data16
1: 0f 38 db aesimc %xmm1,%xmm1
4: c8 66 0f 3a enterq $0xf66,$0x3a
8: 44 da 04 66 rexX fiaddl (%rsi,2)
c: 0f 3a 44 ec 10 pclmullqhqdq %xmm4,%xmm5
11: 66 data16
12: 0f .byte 0xf
13: 3a df cmp %bh,%bl
15: fe 08 decb (%rax)
With these changes:
0: 66 0f 38 db c8 aesimc %xmm0,%xmm1
5: 66 0f 3a 44 da 04 pclmulqdq $0x4,%xmm2,%xmm3
b: 66 0f 3a 44 ec 10 pclmullqhqdq %xmm4,%xmm5
