------- Comment #17 from pinskia at gcc dot gnu dot org 2005-11-04 18:06 -------
Variable: local_paca, UID 1270, struct paca_struct *, is global, call
clobbered, default def: local_paca_1
But we get:
# TMT.6_8 = V_MAY_DEF <TMT.6_7>;
# VUSE <local_paca_1>;
foo ();
I don't understand why because to me r13 should be able to change in foo so we
should get V_MAY_DEF there.
