Dan Liew dbb7f616c1 More LSan workarounds. 2017-10-16 08:56:17 +01:00
Dan Liew 35f6746c60 Workaround regressions/smt2/error.smt2 test timing out. 
When ASan's LeakSanitizer is enabled leak checking is triggered
when `exit()` is called and it returns so many false positives that
it takes a long time to write them to the console.

To workaround this we simply call `_Exit()` instead.

Nikolaj Bjorner 77008dc411 Merge pull request #1226 from NikolajBjorner/master 
removing dependencies on simplifier, support SMTLIB2 parametric algebraic datatypes.
This is a breaking change. It introduces two substantial changes:
1. The legacy simplifier is removed. It was obsoleted with the introduction of the rewriter facilities, but many dependencies made it a major change to remove the legacy simplifier. All uses of the legacy simplifier have now been replaced by corresponding calls to the rewriter. It means that some normalization may behave differently. At this point, Z3 passes regressions and passes performance tests without regressing.
2. Algebraic datatypes in the form of SMT-LIB2.6 are now supported. These generalize the datatypes supported so far as parametric datatype constructors may be applied to different arguments within a recursive definition.
