EvalBoolean()

ConstantFolding::boolean_result_t ConstantFolding::EvalBoolean ( const ::wasm::Expression *  expr )

static

Tries to evaluate the given boolean expression expr using constant folding.

Returns UNDEF if the expression cannot be evaluated at compile time, TRUE if the expression evaluates to true at compile time, and FALSE otherwise. Currently supported are only expressions consisting of a single boolean constant, a negation (tested using eqZ instruction) of a constant boolean expression, and conjunctions or disjunctions of constant boolean expressions. Expressions like x == x are currently not supported.
