2019-08-01Fix memory leak in rewriter (debug mode). (#3141)Mathias Preiner
s_rewriteStack in rewriter.cpp was not properly cleaned up. This commit wraps s_rewriteStack in a std::unique_ptr to automatically free the memory.

2019-07-29Refactoring of bit-vector elimination rules (#3105)yoni206
This commit makes the following minor refactors to src/theory/bv/theory_bv_rewrite_rules_operator_elimination.h: - Including options/bv_options.h: this is needed because this header file is being used. - Marking all functions as inline: details in a discussion inside the PR.

2019-06-18 Strings: More aggressive skolem normalization (#2761)Andres Noetzli
This PR makes the skolem normalization in the string solver quite a bit more aggressive by reducing more skolems to prefix and suffix skolems. Experiments show that this PR significantly improves performance on CMU benchmarks.
2019-06-13Add lemma for the range of values of str.indexof (#3054)Andres Noetzli
This commit adds a lemma that the value of `str.indexof(x, y, n)` must be between -1 and `str.len(x)`.
