DECL_RESULT holds a RESULT_DECL node for the value of a function,
or it is 0 for a function that returns no value.
(C functions returning void have zero here.)
- DECL_RESULT_TYPE holds the type in which the result is actually
- returned. This is usually the same as the type of DECL_RESULT,
- but (1) it may be a wider integer type and
- (2) it remains valid, for the sake of inlining, even after the
- function's compilation is done.
+ The TREE_TYPE field is the type in which the result is actually
+ returned. This is usually the same as the return type of the
+ FUNCTION_DECL, but it may be a wider integer type because of
+ promotion.
DECL_FUNCTION_CODE is a code number that is nonzero for
built-in functions. Its value is an enum built_in_function
that says which built-in function it is.
The type should be void and the value should be ignored. */
