formulas

type t = Int_lit.t

The type of atomic formulas over terms.

val equal : t -> t -> bool

Equality over formulas.

val hash : t -> int

Hashing function for formulas. Should be such that two formulas equal according to Expr_intf.S.equal have the same hash.

val pp : t Msat.Solver_intf.printer

Printing function used among other thing for debugging.

val neg : t -> t

Formula negation

val norm : t -> t * Msat.Solver_intf.negated

Returns a 'normalized' form of the formula, possibly negated (in which case return Negated). norm must be so that a and neg a normalise to the same formula, but one returns Negated and the other Same_sign.
