# twice) under MAKEPAD_RUN_WARM_STRICT. Every run must exit 0 and print the cold run's result line; the
# last run must run no initializer (its statics and constants come from their value entries) and
# compile nothing (higher-ranked fn-pointer types are keys). Prints "cache_warm_statics: ok" or
# "cache_warm_statics: FAILED ...".
