Typedef Documentation

sub_expression_mapt

using sub_expression_mapt = std::unordered_map<exprt, smt_termt, irep_hash>

Post order visitation is used in order to construct the the smt terms bottom upwards without using recursion to traverse the input exprt.

Therefore the convert_expr_to_smt overload for any given type of exprt, will be passed a sub_expression_map which already contains the result of converting that expressions operands to smt terms. This has the advantages of -

• avoiding the deeply nested call stacks associated with recursion.
• supporting wider scope for the conversion of specific types of exprt, without inflating the parameter list / scope for all conversions.

smt_termt convert_expr_to_smt ( const address_of_exprt & address_of, const sub_expression_mapt & converted, const smt_object_mapt & object_map )

static

This conversion constructs a bit vector representation of the memory address. This address is composed of 2 concatenated bit vector components. The first part is the base object's unique identifier. The second is the offset into that object. For address of symbols the offset will be 0. The offset may be non-zero for cases such as the address of a member field of a struct or a the address of a non-zero index into an array.

template<typename factoryt>

smt_termt convert_multiary_operator_to_terms ( const multi_ary_exprt & expr, const sub_expression_mapt & converted, const factoryt & factory )

static

Converts operator expressions with 2 or more operands to terms expressed as binary operator application.

Parameters

expr	The expression to convert.
converted	Map for looking up previously converted sub expressions.
factory	The factory function which makes applications of the relevant smt term, when applied to the term operands.

The conversion used is left associative for instances with 3 or more operands. The SMT standard / core theory version 2.6 actually supports applying the and, or and xor to 3 or more operands. However our internal smt_core_theoryt does not support this currently and converting to binary application has the advantage of making the order of evaluation explicit.
