tree convert_to_complex ( )

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

References convert(), error(), and save_expr().

tree convert_to_fixed ( )

Convert EXPR to some fixed-point type TYPE.

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

References build_fixed(), convert(), error(), FCONST0, FCONST1, integer_onep(), and integer_zerop().

tree convert_to_integer ( )

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.

These routines are somewhat language-independent utility function

Convert EXPR to some pointer or reference type TYPE.
   EXPR must be pointer, reference, integer, enumeral, or literal zero;
   in other cases error is called.

tree convert_to_real ( )

Convert EXPR to some floating-point type TYPE.

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

References build_call_expr(), builtin_mathfn_code(), convert(), error(), excess_precision_type(), fold(), mathfn_built_in(), real_can_shorten_arithmetic(), strip_float_extensions(), and type().

tree convert_to_vector ( )

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

References error(), and tree_int_cst_equal().
