convert_to_complex()

tree convert_to_complex ( tree type, tree expr )

extern

A wrapper around convert_to_complex_1 that always folds the
expression.   

References convert_to_complex_1().

convert_to_complex_maybe_fold()

tree convert_to_complex_maybe_fold ( tree type, tree expr, bool dofold )

extern

A wrapper around convert_to_complex_1 that only folds the
expression if DOFOLD, or if it is CONSTANT_CLASS_OR_WRAPPER_P.   

References CONSTANT_CLASS_OR_WRAPPER_P, convert_to_complex_1(), and preserve_any_location_wrapper().

Referenced by convert_to_complex_nofold().

convert_to_complex_nofold()

tree convert_to_complex_nofold ( tree t, tree x )

externinline

References convert_to_complex_maybe_fold().

convert_to_fixed()

tree convert_to_fixed ( tree type, tree expr )

extern

Convert EXPR to some fixed-point type TYPE.

EXPR must be fixed-point, float, integer, or enumeral;
in other cases error is called.

Convert EXPR to some integer (or enum) type TYPE.

EXPR must be pointer, integer, discrete (enum, char, or bool), float,
fixed-point or vector; in other cases error is called.

The result of this is always supposed to be a newly created tree node
not in use in any existing structure.

expression.

convert_to_vector()

tree convert_to_vector ( tree type, tree expr )

extern

Convert EXPR to the vector type TYPE in the usual ways.

preserve_any_location_wrapper()

tree preserve_any_location_wrapper ( tree result, tree orig_expr )

extern

Subroutine of the various convert_to_*_maybe_fold routines.

If a location wrapper has been folded to a constant (presumably of
a different type), re-wrap the new constant with a location wrapper.
