reg_equiv_mem and reg_equiv_address are NULL for true_regnum == -1

[Kugan]

Hi All,

I am looking at https://gcc.gnu.org/bugzilla/show_bug.cgi?id=62254.

Here, in arm_reload_in, for REG_P (ref) which has true_regnum (ref) ==
-1, both reg_equiv_mem (REG_P (ref)) and  reg_equiv_address (REG_P
(ref)) are NULL. Can this happen?

Thanks,
Kugan
