Bug #: 13207
Summary: Provide a script to advance two versions of a program
and find where they diverge.
Product: gdb
Version: HEAD
Status: NEW
Severity: enhancement
Priority: P2
Component: external
AssignedTo: unassigned@sourceware.org
ReportedBy: dje@google.com
Classification: Unclassified
Sometimes one has a debugging situation where a program worked yesterday, it
doesn't work today, and it's taking awhile to figure out where the breakage is.
IWBN to have a script that could advance two versions of a program and find
where they diverge. Determining divergence can be tricky - functions may not
live at the same address and may be different (however slightly). Maybe the
basic machinery of advance/test/repeat could be parameterized to handle the
easier scenarios and leave it at that.
Such a script feels like more of a contrib-like patch, than part of gdb proper,
but it still feels like something gdb could/should provide.
When it works, it's a real timesaver, and the basic infrastructure shouldn't be
that hard to write in python (and if it is then we've found good places where
python needs to be extended).

Something called twingdb. It check divergence based on line numbers. I'm sure it could be extended with a more controllable predicate for divergence. <http://permalink.gmane.org/gmane.comp.gdb.devel/27451> Never used it myself though. -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug. ^ permalink raw reply [flat|nested] 4+ messages in thread
