dmd.optimize

Perform constant folding.

Members

Expression_optimize Expression Expression_optimize(Expression e, int result, bool keepLvalue): Constant fold an Expression.
expandVar Expression expandVar(int result, VarDeclaration v): If variable has a const initializer, return that initializer.
setLengthVarIfKnown void setLengthVarIfKnown(VarDeclaration lengthVar, Expression arr): It is possible for constant folding to change an array expression of unknown length, into one where the length is known. If the expression 'arr' is a literal, set lengthVar to be its length.
setLengthVarIfKnown void setLengthVarIfKnown(VarDeclaration lengthVar, Type type): Same as above, but determines the length from 'type'.
