Hello,
Today was the day we targetted for creating the GDB 7.8 branch.
But we still have 2 issues identified as blocking before we can do so:
- Performance issue induced by PR gdb/16253. Not sure if a decision
on how to deal with this regression was reached. Keith and Doug?
- infrun regression on platforms using software single step (Eg AIX).
See PR gdb/17000. A patch was sent this past weekend, and is
awaiting review.
We're going to follow those two AIs day by day until we can branch...

I've been poking at this one all day long. I noticed something while
reviewing it, and then hit a stack of issues. I'll reply very soon.
I think the break-interp.exp crashes should be a blocker too:
https://sourceware.org/ml/gdb-patches/2014-05/msg00731.html
Also, I've now noticed that running the testsuite against
gdbserver has several regressions compared to a month or
so ago. :-/

I'm not sure this is a blocker, but I've started to notice gdb segvs
in corefile.exp.
vdso target sections are not removed when a new core is loaded, and
gdb is referencing memory from an already-freed bfd.
At any rate I'm going to file a pr tomorrow.

That's sounds just like the break-interp.exp crashes mentioned above.
Markus followed up already (silly archives don't cross the month
boundary), but I haven't managed to reply yet, still busy with
the software step stuff.

I've added an entry in the TODO of our wiki page. If you have
a PR, can you add the reference there? From what I understand,
Pedro was going to look at it, so I put his name on the entry.
Can we get a quick update on where we stand on the performance
regression AI?
Thanks!
