Looks good (assuming the detailed description is more correct than the
high-level one in AMD's doc), thank you.

Ah no, I was wrong, sorry about that:
The VFRCZSS and VFRCZSD instructions extract the fractional portion of the
single-/double-precision scalar floating-point value in an XMM register or 32-
or 64-bit memory l

Uros, I can't seem to find the AMD documentation anymore (marketing has gotten
hold of the website and tech info got hidden somewhere deep), but if I remember
correctly, vfrczsd %xmm0, %xmm1 does:
xmm0[0]=frcz(

_mm_frcz_ss is inconsistent between compilers. Microsoft gives it 2 arguments
and movss-like semantics, whereas clang gives it a single argument. AMD doesn't
document intrinsics,
