Get the assumption field from a ipasir$a.
(ipasir$a->assumption x) → assumption
This is an ordinary field accessor created by fty::defprod.
Function:
(defun ipasir$a->assumption$inline (x) (declare (xargs :guard (ipasir$a-p x))) (declare (xargs :guard t)) (let ((__function__ 'ipasir$a->assumption)) (declare (ignorable __function__)) (mbe :logic (b* ((x (and t x))) (lit-list-fix (cdr (std::da-nth 1 x)))) :exec (cdr (std::da-nth 1 x)))))
Theorem:
(defthm lit-listp-of-ipasir$a->assumption (b* ((assumption (ipasir$a->assumption$inline x))) (lit-listp assumption)) :rule-classes :rewrite)
Theorem:

Theorem:
(defthm ipasir$a->assumption$inline-ipasir$a-equiv-congruence-on-x (implies (ipasir$a-equiv x x-equiv) (equal (ipasir$a->assumption$inline x) (ipasir$a->assumption$inline x-equiv))) :rule-classes :congruence)
