From e7f703804d7dadbd57cf7c50f479324d012f09e7 Mon Sep 17 00:00:00 2001 From: "Mikhail R. Gadelha" Date: Sat, 16 Jun 2018 14:36:17 +0000 Subject: [PATCH] [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.
