Ensure-function/lambda-guard-verified-exec-fns

Cause an error if a function or lambda expression is a non-guard-verified function or a lambda expression that calls some non-guard-verified function, except possibly in the :logic subterms of mbes.

Signature

(ensure-function/lambda-guard-verified-exec-fns 
     fn/lambda description 
     error-erp error-val ctx state) 
 
  → 
(mv erp val state)

Arguments

fn/lambda — Function or lambda expression to check.
    Guard (pseudo-termfnp fn/lambda).

description — Guard (msgp description).

error-erp — Flag to return in case of error.

error-val — Value to return in case of error.

ctx — Context for errors.

Returns

erp — nil or error-erp.

val — nil if erp is nil, otherwise error-val.

This error-checking function is useful after calling ensure-function/macro/lambda (which returns the pseudo-termfnp) to handle functions and lambda expressions uniformly. The description parameter should describe the function or lambda expression.
