Optimize interpreter hot paths for arithmetic, comparisons, and control flow by lahma · Pull Request #2345 · sebastienros/jint (original) (raw)

…ol flow

Add double fast paths to arithmetic operators (Plus, Minus, Times, Divide) that skip ToPrimitive/ToNumeric overhead for JsNumber operands. Simplify CompareNumber to check integer type first and handle NaN directly instead of falling back to CompareComplex. Move Remainder's integer check before ToNumeric conversion. Add GetBooleanValue virtual method to JintExpression with overrides on 7 comparison operators, and use it in for-loop, while-loop, and if-statement conditions to avoid JsBoolean wrapper allocation and ToBoolean virtual dispatch.
