Subject: Fix option handler for lazy/bv-sat-solver combinations. (#2225)
X-Git-Tag: cvc5-1.0.0~4844
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=0b2eb659087dd3643e57fe39ee84f6cb42721e94;p=cvc5.git

Fix option handler for lazy/bv-sat-solver combinations. (#2225)

Further, unifies all *limitHandler and *limitPerHandler to limitHandler.
