constant folding

Computing Dictionary

constant folding definition

compiler
A compiler optimisation technique where constant subexpressions are evaluated at compile time. This is usually only applied to built-in numerical and boolean operators whereas partial evaluation is more general in that expressions involving user-defined functions may also be evaluated at compile time.
