Right, it's gone in this weekend's bootstraps.

I did not find this failure in your latest test results
(http://gcc.gnu.org/ml/gcc-testresults/2013-11/msg01857.html) and so I
assume it has been also fixed by any of the subsequent patches
addressing other issues.

Thanks a lot.  I committed the patch a few moments before reading your
comment so I suppose trunk now suffers from this failure.  If so, can
you please open a bug report?

I tried to reproduce it on gcc54 on the compile farm (sparc64-linux)
but so far I have failed to even build the gcc itself there :-/

I've now regression-tested the patch on sparc-sun-solaris2.11.
Bootstrap works and I find just a single regression:

FAIL: gfortran.fortran-torture/execute/pr32604.f90 execution,  -O2
-fbounds-check 

which is reproducible.

--- Comment #11 from Martin Jambor  ---
I have re-submitted my patch in which this bug is fixed, you can find
it at http://gcc.gnu.org/ml/gcc-patches/2013-11/msg00598.html

I have verified the patch bootstraps on i686-linux (reported by Jakub
in the mailing list), ppc64-linux (some problem reported by David in
comment #8) and ia64-linux (no problem reported but anyway), however I
could not try the same on Sparc or Solaris (even though failure was
reported by Rainer in comment #1) because I do not have access to
either of them (oh how I wish that sparcs on the compile farm came
back).

Similarly, I have verified that the original reported failure on
cris-elf cross-compiler goes away, as does the problem on sh-none-elf
cross (the one from comment #4).  However, even without the fix I was
not able to reproduce the failure on arm reported in comment #6.

If anyone is willing to test the patch on any platform but especially
on those which I could not, I'd be very grateful.  Thanks.

And arm-none-eabi builds in newlib. Let's join the party.
