Subject: [analyzer] Add method to the generic SMT API to dump the SMT formula
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=c36069cffc57a30a20782bf327a87bed4e48a6c2;p=clang

[analyzer] Add method to the generic SMT API to dump the SMT formula

Summary:
New method dump the SMT formula and the Z3 implementation.

There is no test because I only used it for debugging.

However, if requested, I can add an option to the static analyzer to dump the formula (whole program? per path?), maybe something like the trimmed graph but for SMT formulas.
