This is normally useful for back ends which wish to implement a pragma by using the attributes which correspond to the pragma's effect. The @var{node} argument is the decl which is being created. The @var{attr_ptr} argument is a pointer to the attribute list -for this decl. The @var{prefix_ptr} is a pointer to the list of -attributes that have appeared after the specifiers and modifiers of the -declaration, but before the declaration proper. +for this decl. The list itself should not be modified, since it may be +shared with other decls, but attributes may be chained on the head of +the list and @code{*@var{attr_ptr}} modified to point to the new +attributes, or a copy of the list may be made if further changes are +needed. @findex SET_DEFAULT_DECL_ATTRIBUTES @item SET_DEFAULT_DECL_ATTRIBUTES (@var{decl}, @var{attributes}) |
