Use it wherever it is you need to know whether a symbol has your
attribute (I don't know when you need the information). In RTL you can
normally find the VAR_DECL using MEM_EXPR or REG_EXPR.
Ian
RIBUTES(DECL))) {
SYMBOL_REF_FLAGS(XEXP (rtl, 0)) |= SYMBOL_MYATTR_FLAG;
}
}
As I mentioned, this allows me to flag all of the globals/static locals but
does nothing for locals.

tag later. How can I do the
same for locals?
