--- Comment #3 from Martin Jambor <jamborm at gcc dot gnu.org> ---
And while I am at it, the 2.5% slowdown in April was caused by Richi's
r14-332-g24905a4bd1375c (Adjust costing of emulated vectorized
gather/scatter) and the 2.8% regression in May by 2.8% is caused by
r14-1371-ge5405f065bace0 (Handle FMA friendly in reassoc pass).
Both are small and so may not warrant their own bug-report but together
they make up almost 6% and we are now 13% slower than GCC 13 on zen 3
and 2 (on the Intel machine in LNT it is just 2.7% and I see no
regression on the Aarch64 one).
