Comment 2 Jakub Jelinek 2023-06-14 08:02:57 UTC 
This was fixed upstream for GCC 9 and later in https://gcc.gnu.org/PR87723
We just need to cherry-pick that fix, should apply cleanly.

Short testcase -O2 -march=z10:
unsigned long
foo (unsigned long x, unsigned long y)
{
  unsigned long z = (x << 57) | (x >> 7);
  z &= 0xfe00000000000000UL;
  return z | y;
}
