Functions
def_t *	alias_def (def_t *def, struct type_s *type, int offset)
	Create a def that aliases another def. More...

Temporary defs
Temporary defs are used for recycling memory for tempary variables. They always have names in the form of .tmpN where N is a non-negative integer. The type of the temporary def can change throughout its life, but the size will never change. Temporary defs are bound to the current function (current_func must be valid). They are always allocated from the funciont's local defspace.
def_t *	temp_def (etype_t type, int size)
	Get a temporary def. More...
void	free_temp_def (def_t *temp)
	Free a tempary def so it may be recycled. More...
