Parameters

module B : Backend

Signature

Sourceval init_backend : unit -> unit

Sourcetype backend_context = B.backend_context

Sourceval make_context : Shared_ast.decl_ctx -> backend_context

Sourcetype vc_encoding = B.vc_encoding

Source

val translate_expr : 
  backend_context ->
  Shared_ast.typed Dcalc.Ast.expr ->
  backend_context * vc_encoding

Source

val encode_asserts : 
  backend_context ->
  Shared_ast.typed Dcalc.Ast.expr ->
  backend_context

Sourcetype model = B.model

Sourcetype vc_encoding_result =

| Success of vc_encoding * backend_context
| Fail of string

Source

val print_negative_result : 
  Conditions.verification_condition ->
  backend_context ->
  model option ->
  string

Source

val encode_and_check_vc : 
  Shared_ast.decl_ctx ->
  (Conditions.verification_condition * vc_encoding_result) ->
  bool

encode_and_check_vc spawns a new Z3 solver and tries to solve the expression vc. Returns true if the vs was proven true and false otherwise. *
