- Subject: Estimates for gdb bugzillas
Here are some *really* rough estimates on some of the bugs I have
gleaned out of the gdb bz data base. Not being familiar with the gdb
code base yet, I welcome any ideas/comments/corrections if anyone feels
I am way off base. The granularity I am using is one month. Also,
being a newbie to gdb I will estimate based on this experience instead
of someone more "gdb-experienced".
As for these bz's:
1111 - ptype prints return value for constructors in templated classes
1112 - can't breakpoint in destructor
1113 - ptype claims that destructors take an int arg
After a conversation with Sami/Keith on our weekly call yesterday, it
sounds like these may be resolved with a patch Daniel has pending. So,
I'll wait until his patch goes in and see if it makes a difference. If
it doesn't, I'll estimate then.
1593 - problem with nested namespaces
appears to be fixed in HEAD.
For bz 1734 (gdb does not store an empty class) I would guesstimate
about a month for this if it is indeed a gdb problem. It may take some
more digging to be sure it is and not a gcc problem. If anyone knows
more, please jump in.
For bz 1783/2271/2273(all seem to be same - gdb can't lookup class
typedef when in methods of class) I will guesstimate about 2 months
for this, again hoping this is only a gdb bug and does not require mods
to gcc to implement. The ominous note left by Jim Ingham("Not sure how
to fix this without breaking other legitimate cases of namespace lookup,
however"), a highly knowledgeable and well-known gdb hacker, makes me
think this could open a real can of worms.
For bz 1817(double-colon not understood in typecast ) I would
guesstimate about a month, although I would hope it could be done in less.
There are also a couple of bugs in the gcc data base(7932 - Emit debug
information about non-type templates, 30161 - gcc should generate dwarf
info about templates) that popped up that are still open. Until we
actually run into gdb bugs that look like they require these fixes we
will raise their priority.
All comments/suggestions/ideas welcome.
