Public bug reported:
The upstream gcc-15 compiler does not support -mach with extension supm
for pointer masking.
Extension supm is mandated by the RVA23U64 profile.
Upstream patch
7e5f5fd101f8 ("RISC-V: Minimal support for ssnpm, smnpm and smmpm extensions.")
is enough to accept extension supm in the -march parameter.
Please, add the patch to our gcc-15.
** Affects: gcc-15 (Ubuntu)
Importance: Undecided
