* There are three kinds of symbolic constants:
- * symconst_type_tag The symbolic constant represents a type tag.
- * symconst_size The symbolic constant represents the size of a class.
- * symconst_addr_name Information for the linker, e.g. the name of a global
- * variable.
+ * symconst_type_tag The symbolic constant represents a type tag.
+ * symconst_type_size The symbolic constant represents the size of a type.
+ * symconst_type_align The symbolic constant represents the alignment of a type.
+ * symconst_addr_name Information for the linker, e.g. the name of a global
+ * variable.
+ * symconst_addr_name The symbolic constant represents the address of an entity.
+ *
* To represent a pointer to an entity that is represented by an entity
* datastructure don't use
* new_SymConst((type_or_id*)get_entity_ld_ident(ent), symconst_addr_name);.
* Use a real const instead:
- * new_SymConst(mode_P_mach, tarval_p_from_entity(ent));
+ * new_SymConst(ent, symconst_addr_ent);
* This makes the Constant independent of name changes of the entity due to
* mangling.
*
* Attributes:
* attr.i.num The symconst_addr_ent, i.e. one of
* -symconst_type_tag
- * -symconst_size
- * - symconst_addr_name
- * If the attr.i.num is symconst_type_tag or symconst_size, the node contains an attribute
+ * -symconst_type_size
+ * -symconst_type_align
+ * -symconst_addr_name
+ *
+ * If the attr.i.num is symconst_type_tag, symconst_type_size or symconst_type_align,
+ * the node contains an attribute:
+ *
* attr.i.*type, a pointer to a type_class. The mode of the node is mode_Is.
* if it is linkage_ptr_info it contains
* attr.i.*ptrinfo, an ident holding information for the linker. The mode
* node.
