Summary|[SSE4.1] missing support |[SSE4.1] missing support
|for PMAXUD |for PMAXUD (x86)
--- Comment #1 from Mark Wielaard <m...@klomp.org> ---
Note that this is implemented for amd64, just not for x86 (32bit).
See VEX/priv/guest_amd64_toIR.c (dis_ESC_0F38__SSE4):
case 0x3B:
case 0x3F:
/* 66 0F 38 3B /r = PMINUD xmm1, xmm2/m128
Minimum of Packed Unsigned Doubleword Integers (XMM)
66 0F 38 3F /r = PMAXUD xmm1, xmm2/m128
Maximum of Packed Unsigned Doubleword Integers (XMM)
*/
if (have66noF2noF3(pfx) && sz == 2) {
/* FIXME: this needs an alignment check */
Bool isMAX = opc == 0x3F;
delta = dis_SSEint_E_to_G(
vbi, pfx, delta,
isMAX ? "pmaxud" : "pminud",
isMAX ? Iop_Max32Ux4 : Iop_Min32Ux4,
False
);
goto decode_success;
}
break;
With tests in none/tests/amd64/sse4-64.c.
