Murphy Berzish bc91d182bf mk_concat fixes WIP 2016-08-03 13:39:14 -04:00
Murphy Berzish 3c2fe497de modify theory_str::get_value() to check EQC for a numeral 
Instead of asking the arithmetic theory for the current assignment,
we return the (unique) numeral in the equivalence class of the term
whose length we want to know.

This is because the arithmetic theory may return a default / internal
value that doesn't correspond to anything actually asserted by the core solver.
 2016-08-02 16:44:54 -04:00
Murphy Berzish 45c4954959 add debugging to theory_str::get_len_value in preparation for fixes 2016-08-02 14:52:44 -04:00
Murphy Berzish a51ad07e3f crash avoidance in propagation of basic string axioms and gen_len_test_options 2016-08-01 20:52:49 -04:00
Murphy Berzish 97f07a8a7c fix debugging statements in theory_str::gen_len_test_options 
this fixes charAt-007.smt2 and prevents two unique crashes
 2016-08-01 18:14:56 -04:00
Murphy Berzish ee1af96f1b add opt_NoQuickReturn_IntegerTheory check in theory_str::new_eq_check() 
This allows us to assert an "inconsistent length" axiom from the integer theory
while continuing in new_eq_handler(). Currently active when
opt_NoQuickReturn_IntegerTheory is 'true' but this may be necessary
here and in other places, in general, to fix integer theory integration.

Murphy Berzish 1c518be61d new_eq_handler improvements in theory_str, WIP 2016-07-27 12:46:35 -04:00
Murphy Berzish f555074e27 add option to disable integer theory integration in theory_str; this is currently ENABLED 2016-07-23 23:29:56 -04:00
Murphy Berzish 02a66c425e add option to bypass quick returns in integer theory integration in theory_str 
this might not actually be that useful, if the problem is, as I suspect it to be,
that values we get from the integer theory need not correspond with
assertions in the core (that can get popped off the stack, etc.)
 2016-07-23 22:43:46 -04:00
Murphy Berzish ac16aa7c81 fix out-of-scope variable bug in theory_str::process_concat_eq_type6 
this fix will have to be made to all functions that use varForBreakConcat

Murphy Berzish 847a5fc1f8 replace old mk_value behaviour in theory_str that creates placeholders for unused terms instead of crashing 2016-07-07 16:13:48 -04:00
Murphy Berzish 9eead64d03 prevent assertion of basic string axioms on variables that go out of scope (theory_str) 
this is testing a crash avoidance feature, the regression is tests/z3str/regex-026.smt2

this also adds some debugging code for a substr() crash but that is WIP

Murphy Berzish b53da182b6 fix gen_assign_unroll_reg so that it does not assert a contradiction 2016-06-30 04:39:09 -04:00
Murphy Berzish a2d6149df5 add general-case regex unroll model generation 
WIP as there is currently a SAT-as-UNSAT bug I'm trying to fix

This also changes the semantics of lower_bound and upper_bound,
no longer wrapping the expr that is passed in with mk_strlen().
This actually makes these methods useful for checking bounds
of things other than strings.
