Guard-verified-fnsp

Check if a term calls only guard-verified functions.

Signature

(guard-verified-fnsp term wrld) → yes/no

Arguments

term — Guard (pseudo-termp term).

wrld — Guard (plist-worldp wrld).

Returns

yes/no — Type (booleanp yes/no).

Note that if any function inside the :logic component of an mbe or called via ec-call is not guard-verified, we return nil, even when term could otherwise be fully guard-verified. See guard-verified-exec-fnsp for a similar utility that ignores the guard verification status of functions in the :logic components of mbes or called via ec-call.

The name of this function is consistent with the name of logic-fnsp in the ACL2 source code.
