stp

STP is an efficient decision procedure for the validity (or satisfiability) of
formulas from a quantifier-free many-sorted theory of fixed-width bitvectors
and (non-extensional) one-dimensional arrays. The functions in STP's input
language include concatenation, extraction, left/right shift, sign-extension,
unary minus, addition, multiplication, (signed) modulo/division, bitwise
Boolean operations, if-then-else terms, and array reads and writes. The
predicates in the language include equality and (signed) comparators between
bitvector terms.
