Looking at Patrick's old list, the following bugs are still open

Aldy, you wanted to take a look. Were you able to reproduce?
I haven't looked at it in a long time...

I haven't yet.


   * [trans-mem] problem with TM clone aliases
     Leads to add _ITM_getTMCloneOrIrrevocable in a __transaction_atomic.
     ->  Fix proposed.
     http://gcc.gnu.org/bugzilla/show_bug.cgi?id=51516

Aldy, has this been fixed? You said you were waiting for review.

Just committed a fix for this and closed the PR.


   * ICE when lto1 does not have -fgnu-tm and object file uses TM
     http://gcc.gnu.org/bugzilla/show_bug.cgi?id=51280

Still open?

Last I looked I couldn't reproduce.  Torvald, perhaps you could see if 
you can reproduce on your end?


Probably should be closed:
   * libitm failures
     http://gcc.gnu.org/bugzilla/show_bug.cgi?id=51124

Can be closed? the static ctor part is
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=51173

I just closed this as it was an assortment of distinct failures reported 
by a variety of people on different architectures (some of which were 
already fixed).  I have suggested in the notes that individual PRs be 
filed if problems are still present.  A generic "libitm failures" PR 
doesn't help.
