+ * alpha-nat.c, irix4-nat.c, irix5-nat.c, mipsv4-nat.c,
+ sparc-tdep.c (supply_gregset, supply_fpregset): Fill inaccessible
+ registers with zero to handle recent read_register_bytes change.
+ * irix4-nat.c, irix5-nat.c, mipsv4-nat.c (supply_gregset,
+ fill_gregset): Fix handling of CAUSE_REGNUM.
+ * mips-nat.c (store_inferior_registers): Handle unwritable
+ registers when storing a single register.
+ * config/mips/tm-irix3.h (CAUSE_REGNUM, BADVADDR_REGNUM):
+ Fix definitions.
+
+ * mdebugread.c (parse_symbol, psymtab_to_symtab_1): Clear
+ allocated mips_extra_func_info, if the debug info is corrupt,
+ the PDR to fill it in might be missing.
