# -march=native was here and has been dropped: measured ~12% *slower* than plain -O3 on
# Zen 4, worst on numeric loops (-16% integer, -21% float). Microbenchmarks are the
# friendliest case for it, so there's no reason to expect a win on real work either.
#
# -fno-strict-overflow guards fixnum overflow checks that assume signed overflow wraps —
# undefined behaviour GCC exploits from -O2 up. 2.5 uses builtin overflow intrinsics and
# doesn't strictly need it, but it's free (within noise here) and keeps every definition
# in this repo on the same flags.
