Subject: [Bug target/115115] [12/13/14/15 Regression] highway-1.0.7 wrong _mm_cvttps_epi32() constant fold

--- Comment #11 from Sergei Trofimovich <slyfox at gcc dot gnu.org> ---
After `highway` applied a masking fix to `highway/master` `gcc-15` still fails
to pass the `HwyConvertTestGroup/HwyConvertTest.TestAllF2IPromoteTo/SSE2`.
I tried to reduce the test with more care and I think it's a new `gcc-15`
regression related to constant folding in vector shifts. Filed
https://gcc.gnu.org/PR115161
And somewhat related:
> 972 - HwyShuffle4TestGroup/HwyShuffle4Test.TestAllPer4LaneBlockShuffle/SSE2 # GetParam() = 16384 (Subprocess aborted)
from the #comment1 is a separate `gcc-15` regression related to vector
rotations: https://gcc.gnu.org/PR115146. It's (pending) fix does not help the
`TestAllF2IPromoteTo/SSE2` above.
Thus it looks like all the bugs are independent and require separate fixes.
