Function Documentation

◆ 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(), ggc_alloc(), 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

◆ 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_to_integer()

tree expr )
extern

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.

◆ convert_to_integer_maybe_fold()

tree convert_to_integer_maybe_fold ( tree type,

tree x )
externinline

◆ convert_to_pointer()

tree convert_to_pointer ( tree type,
tree expr )
extern
A wrapper around convert_to_pointer_1 that always folds the
expression.   

References convert_to_pointer_1().

Referenced by oacc_rewrite_var_decl().

◆ convert_to_pointer_maybe_fold()

tree convert_to_pointer_maybe_fold ( tree type,
tree expr,
bool dofold )
extern
A wrapper around convert_to_pointer_1 that only folds the
expression if DOFOLD, or if it is CONSTANT_CLASS_OR_WRAPPER_P.

tree expr )
extern

expression.

◆ convert_to_real_maybe_fold()

tree convert_to_real_maybe_fold ( tree type,
tree expr,
bool dofold )
extern
A wrapper around convert_to_real_1 that only folds the
expression if DOFOLD, or if it is CONSTANT_CLASS_OR_WRAPPER_P.

◆ convert_to_vector()

tree convert_to_vector ( tree type,

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.
