When reading a core file register section which is larger than expected, emit a warning. Assume that a register section usually has exactly the size specified by the regset section iterator. In some special cases this assumption is wrong, or at least does not match the regset supply function's logic. Thus also add a way to suppress the warning in those cases, using a new flag REGSET_VARIABLE_SIZE. gdb/ChangeLog: * regset.h (struct regset): Add flags field. (REGSET_VARIABLE_SIZE): New value for a regset's flags field. * corelow.c (get_core_register_section): Add warning if the size exceeds the requested size and the regset does not have the REGSET_VARIABLE_SIZE flag set. * alphanbsd-tdep.c (alphanbsd_gregset): Add REGSET_VARIABLE_SIZE flag. * armbsd-tdep.c (armbsd_gregset): Likewise. * hppa-hpux-tdep.c (hppa_hpux_regset): Likewise. * hppaobsd-tdep.c (hppaobsd_gregset): Likewise. * m68kbsd-tdep.c (m68kbsd_gregset): Likewise. * mipsnbsd-tdep.c (mipsnbsd_gregset): Likewise.
