# x64_gate.sh: the landing gate's x64 leg (JITSAFE fix 5), run from the tree root on an x86_64 node
# (relax-campaign/x64gate.sh ships the exact tree there through pool.sh). The Mac leg of land.sh is
# arm64; x64-only regressions (O1 switch, X64RACE, AVX-512 checksums) reached work through it.
#   1. cargo build --release -p makepad-run: 0 warnings
#   2. cargo test --release -p relax-backend -p relax-codegen (every x64 test)
#   3. diff_fast at o1 / base / o3 / counted, hard RIR verification on (DIFF_VERIFY default)
# Prints one verdict line: `X64-OK <diff line>` or `X64-FAIL: <what>`; exit 0 / 1.
# Env: X64_GATE_KNOWN="test::name ...": x64 test failures that do not fail the gate (none today).
