InvalidOpCodeException: opcode=0xAF (No IMUL 32bit support)

Open JorisVanEijden opened this issue 2 years ago • 0 comments

The following assembly:

1000:11AE 66 8B 46 0A                       mov     eax, [bp+arg_4]
1000:11B2 66 0F AF 46 0E                    imul    eax, [bp+arg_8]
1000:11B7 66 89 46 FC                       mov     [bp+var_4], eax
1000:11BB EB 63                             jmp     short loc_11220

Causes an InvalidOpCodeException: opcode=0xAF at 0x1000:0x11B2

The 0F AF version of imul has not been implmented yet See: https://www.felixcloutier.com/x86/imul
