# Production nodes run on x86-64-v3-capable hardware (Haswell / Excavator+,
# ~2013+), so we compile with that ISA baseline to let rustc emit AVX2/BMI2
# and friends. Scoped to x86_64 so aarch64 dev machines (Apple Silicon) keep
# building without modification.
#
# Note: `nix/mpc-node.nix` exports its own RUSTFLAGS env var, which *replaces*
# (not merges with) these flags — the Nix build sets `target-cpu=x86-64-v3`
# explicitly there. Keep both in sync.
