I'm seeing similar ICE in xgcc when trying to build GCC-14 for MIPS32;
it goes away when I drop "-fPIC" or "-march=mips32":
/build/./gcc/xgcc -B/build/./gcc -march=mips32 -O2 -c wlocale-inst.ii -fPIC
/build/mipsel-softfloat-linux-gnu/libstdc++-v3/include/bits/locale_facets.tcc:588:7:
error: unable to find a register to spill
