Hi Paolo,
I just did some tests,
> + [0x98] = X86_OP_ENTRY1(CBW, 0,v), /* rAX */
> + [0x99] = X86_OP_ENTRY3(CWD, 2,v, 0,v, None, None), /* rDX, rAX */
> + [0x9A] = X86_OP_ENTRYrr(CALLF, I_unsigned,p, I_unsigned,w, chk(i64)),
X86_TYPE_I_unsigned is defined in patch 11, so the related changes
should be move into this patch to avoid compiling failures:
