the case for i386/i486 targets). The DECL_RTL looks like
(MEM (CONST ...)) even though this variable is a local `auto'
or a local `register' variable. In effect, what has happened
is that the reload pass has seen that all assignments and
references for one such a local variable can be replaced by
equivalent assignments and references to some static storage
variable, thereby avoiding the need for a register. In such
cases we're forced to lie to debuggers and tell them that
this variable was itself `static'. */
