Yes. I have started a thread here:
http://gcc.gnu.org/ml/gcc-patches/2011-12/msg01221.html
But as I said, probably out of my knowledge...

Here some more PR:

* Bug 51698 - [trans-mem] TM runtime and application with LTO

* [libitm, build] Clear hardware capabilities on libitm.so with Sun ld
   http://gcc.gnu.org/ml/gcc-patches/2011-11/msg02093.html
   Not sure to know the status of this (Rainer?). PR?

* Bug 51773 - error building libitm/aatree.cc on ARM

* Bug 51173 - XFAIL: libitm.c++/static_ctor.C
   error: unsafe function call ‘void __cxa_guard_release(long long 
int*)’ within ‘transaction_safe’ function
   error: unsafe function call ‘int __cxa_guard_acquire(long long int*)’ 
within ‘transaction_safe’ function
   The static initialization is using locks. One way to fix that is to 
transform the acq/rel to a transaction, right?

* Bug 51124 - libitm failures
   FAIL: libitm.c++/eh-1.C execution test
   -> Darwin: Xcode 4+ problem 
http://gcc.gnu.org/ml/gcc-patches/2012-01/msg00329.html
   -> Solaris: ?.
