2019-09-06Remove SMT1 parser. (#3228)Mathias Preiner
This commit removes the SMT1 parser infrastructure and adds the SMT2 translations of the SMT1 regression tests. For now this commit removes regression test regress3/pp-regfile.smt since the SMT2 translation has a file size of 887M (vs. 172K for the SMT1 version). Fixes #2948 and fixes #1313.

2019-08-30Fix out-of-bounds access in regexp inclusion test (#3242)Andres Noetzli
If `re.*(re.allchar)` was at the end of a regular expression concatenation, the regular expression inclusion test could cause out-of-bound accesses. For `re.*(re.allchar)`, we were blindly adding the index after it to the set of indices being considered. Later in the loop, we were assuming that all the indices are smaller than the number of components in the concatenation, thus leading to out-of-bound accesses. This commit adds a check before adding the index to the set of indices. Signed-off-by: Andres Noetzli <andres.noetzli@gmail.com>

2019-08-29Better heuristic for str.code/re.range (#3220)Andres Noetzli
To make sure that our `str.code` function is injectve (except for -1 in the codomain), we send the inference that `str.code(x) == -1 v str.code(x) != str.code(y) v x == y` for each pair of `str.code` terms. Because of the order of disjuncts, `str.code(x) != str.code(y)` was usually assigned true. This in turn lead to a difficult problem for the arithmetic engine if there were more `str.code` applications than the size of the domain. E.g. if we had `0 <= str.code(xi) < 10` for 0 <= i <= 10, then the arithmetic engine had a difficult time finding a conflict. This PR improves the heuristic by setting the phase of `str.code(x) != str.code(y)` to false, so we prefer to keep the `str.code` values equal instead of trying to make them different. This change is also reflected in the models produced for inputs involving `str.code`: Previously, we were producing models with different values for the `str.code` whereas now the models are much more uniform. The PR adds two regressions, one testing `str.code` performance directly and one testing it for `str.code` terms generated by `re.range`. Signed-off-by: Andres Noetzli <anoetzli@amazon.com>
2019-08-29Infer conflicts based on regular expression inclusion (#3234)Andres Noetzli
We have a conflict if we have `str.in.re(x, R1)` and `~str.in.re(x, R2)` and `R2` includes `R1` because there is no possible value for `x` that satisfies both memberships. This commit adds code to detect regular expression inclusion for a small fragment of regular expressions: string literals with single char (`re.allchar`) and multichar wildcards (`re.*(re.allchar)`).
