    Sothm-inst-proof

    Proof builder instructions to prove instances of second-order theorems.

    Signature
    (sothm-inst-proof sothm fsbs wrld) → instructions
    Arguments
    sothm — Guard (symbolp sothm).
    fsbs — Guard (fun-substp fsbs).
    wrld — Guard (plist-worldp wrld).
    Returns
    instructions — A true-listp.

    Instances of second-order theorems are proved using the ACL2 proof builder. Each such instance is proved by first using the :functional-instance determined by sothm-inst-pairs, then using the facts computed by sothm-inst-facts on the subgoals. Each sugoal only needs a subset of those facts, but for simplicity all the facts are used for each subgoal, using the proof builder :repeat command. Since sometimes the facts are not quite identical to the subgoals, the proof builder :prove command is used to iron out any such differences.
