From f962539ad23759af4ba8f7eece1946fdc2f50876 Mon Sep 17 00:00:00 2001 From: Andreas Arnez Date: Thu, 15 Jan 2015 10:20:45 +0000 Subject: Warn if core file register section is larger than expected 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. --- gdb/regset.h | 7 +++++++ 1 file changed, 7 insertions(+) (limited to 'gdb/regset.h') diff --git a/gdb/regset.h b/gdb/regset.h index 3585322..d6edaa5 100644 --- a/gdb/regset.h +++ b/gdb/regset.h @@ -43,6 +43,13 @@ struct regset /* Function collecting values in a register set from a register cache. */ collect_regset_ftype *collect_regset; + + unsigned flags; }; +/* Values for a regset's 'flags' field. */ + +#define REGSET_VARIABLE_SIZE 1 /* Accept a larger regset section size + in a core file without warning. */ + #endif /* regset.h */ -- cgit v1.1
