@matrix two opposite ends of the Bad spectrum

@matrix I ran out of emoji reactions so here:
PMULLD xmm1, xmm2/m128
as well as here
PMULDQ xmm1, xmm2/m128
or
PMADDUBSW xmm1, xmm2/m128
or
PMULUDQ xmm1, xmm2/m128
MULPD xmm1, xmm2/m128
MULPS xmm1, xmm2/m128
PMADDUBSW mm1, mm2/m64
PCLMULLQHQDQ xmmreg,xmmrm
IMUL r64, r/m64

yes all of those are x86, there are more ISAs ;)
