Missing instructions for x86

[radare]

• [ ] __asm (bt ecx, eax);
• [x] __asm (pxor xmm0, xmm0);
• [ ] __asm (movdqu xmm0, xmmword [r14]);
• [ ] __asm (movdqa xmmword [r13 + 0x110], xmm0);
• [ ] __asm (movdqa xmmword [rbx], xmm0);
• [ ] __asm (aeskeygenassist xmm1, xmm0, 1);
• [ ] __asm (pshufd xmm0, xmm0, 0xff);
• [ ] __asm (pslldq xmm1, 4);
• [ ] __asm (punpcklqdq xmm1, xmm0);
• [ ] __asm (palignr xmm3, xmm0, 8);

• [x] __asm ("fld qword [local_8h]");
• [x] __asm ("fmul qword [0x0047f570]");
• [x] __asm ("fstp qword [local_10h]");

[rfc2119]

also __asm(imul eax, ebx, imm8)

[wargio]

@elicn can you check the imul? @rfc2119 can you provide an example?

[rfc2119]

imul is fixed, thanks! https://asciinema.org/a/tioh1c9gJk7FCjNE9dPpaDLaI

[wargio]

ok

• [ ] Also missing instructions to work with FPU register stack. Like this:

__asm ("fld qword [local_8h]");
__asm ("fmul qword [0x0047f570]");
__asm ("fstp qword [local_10h]");

[wargio]

added to the list above, thanks

@wargio pxor was already implemented in fb71f5854942123a5fd256b75c5d76e355c61f0d. See here

I checked all the PE from r2r and the MachO from /bin/* and here are the missing one's
