Default-hints

A list of hints added to every proof attempt

Examples:
ACL2 !>(default-hints (w state))
((computed-hint-1 clause)
 (computed-hint-2 clause stable-under-simplificationp))

The value returned by this function is appended to the right of any explicitly provided :[hints] argument of every defthm, thm, and defun event, and similarly for the :guard-hints argument of defun, and, for ACL2(r), the :std-hints argument.

See set-default-hints for a more general discussion. Advanced users only: see override-hints for an advanced variant of default hints that are not superseded by :hints arguments.
