Separation Logic
From CVC4
Logic
CVC4 supports a syntax for separation logic as an extension of the *.smt2 language. Separation logic in CVC4 requires the "all supported" logic:
(set-logic ALL_SUPPORTED)
Syntax
The syntax for the operators of separation logic (points-to, emp, star, wand) is summarized in the following table:
| CVC language | SMTLIB language | C++ API | |
|---|---|---|---|
| Empty heap | N/A
|
(emp X Y)
|
|
| Points-to | N/A
|
(pto X Y)
|
em.mkExpr(kind::SEP_PTO, X, Y);
|
| Separation star | N/A
|
(sep C1 ... Cn)
|
em.mkExpr(kind::SEP_STAR, C1, ..., Cn);
|
| Magic wand | N/A
|
(wand C1 C2)
|
em.mkExpr(kind::SEP_WAND, C1, C2);
|
| Nil element | N/A
|
(as nil T)
|
em.mk;
|
