--- Comment #1 from Peter Cordes <peter at cordes dot ca> ---
Fixed for vsqrtss/sd somewhere in 9.0, but not 8.2.
https://godbolt.org/z/0Gxf05.
The general case of one-input scalar xmm,xmm instructions like vcvtss2sd is
still all over the place, with false deps or wasted xor-zeroing. Reported that
as bug 89071
It seems only VSQRTsd/ss itself was fixed for this; sorry I didn't think of
checking for other one-input instructions when I reported this.
