# gopher64-netplay review gate (issue #16)
#
# Documented gate command (from a clean origin/main checkout):
#   ./scripts/gate.sh
#
# What it does:
#   1. `git submodule update --init --recursive` (parallel-rdp,
#      retroachievements/rcheevos, src/compat/sse2neon) — required by
#      build.rs.
#   2. Wires the review box's user-local provisioning onto PATH/env (only
#      when present; a no-op on hosts with system toolchains):
#        - clang/clang++ from the local LLVM-18 root  (build.rs requires
#          clang for `-flto=thin`)
#        - a real pkgconf + fontconfig/X11 dev pc files (the box has no
#          system pkg-config/fontconfig and no sudo)
#   3. Runs `cargo check --all-targets`.
#
# On AVX2-capable hardware, opt into the optimised CPU target:
#   RUSTFLAGS="-C target-cpu=x86-64-v3" ./scripts/gate.sh
# (RUSTFLAGS REPLACES the config's rustflags for the whole invocation, so
# carry any other flags you need.)
