Hi,

Any file in particular?.

I did a git pull on Wednesday on the 4.8 branch. (and binutils and newlib)
I attached the sh I use to build my cross compiler and the only file I
"touched".

Daniel

preprocessed
by appending -save-temps to the command-line that crashes the compiler.  The

building gcc-4_7-branch instead of gcc-4_8-branch
pass ok
(binutils, GMP, MPFR, MPC, and newlib sources remains the same)
 is some regression introduced in 4.8

A similar problem is seen in the LM32 port:

http://gcc.gnu.org/ml/gcc/2013-03/msg00317.html

It appeared for that in GCC 4.8.0 and is still in GCC 4.8.1.

Adding Nick Clifton to the CC list.

It seems the bug was known about a while back:

Any luck with this Nick?

This looks like it might be similar to bug 57636, which has the same ICE on the
cr16 port.

Suggestion there is that it was introduced in trunk@188870:

Hi Alexandre, I've added you to this bug as it seems to have been caused by
this patch you made:

http://gcc.gnu.org/viewcvs/gcc/trunk/gcc/var-tracking.c?r1=188869&r2=188870

I've got no idea what this code does, but if I removed it, the ICE disappears
on LM32. If you think it is a backend problem, rather than this code, it would
be helpful if you could give some guidance as to what needs changing, as it
seems three targets currently have this problem. Thanks.

--- Comment #32 from Jeffrey A. Law <law at redhat dot com> ---
The problem we're seeing is with the cc0-setter and cc0-user in different
blocks, they're separated by a NOTE_BASIC_BLOCK.

That causes CSE to blow up because it expects that the cc0-setter and cc0-user
are always consecutive.  While we're just seeing the failure in CSE right now,
I'm sure there's a ton of places that assume the setter/user are inseparable as
that has been the documented form for ~20 years.

>From rtl.texi:

 The instruction setting the
condition code must be adjacent to the instruction using the condition
code; only @code{note} insns may separate them.


We either need to relax that and audit all the HAVE_cc0 code to ensure it
doesn't make that assumption, or we need to somehow restore the property that
the setter and user are inseparable.

Alexandre, curiously, applying this patch to the cross-compiler source tree
fixes the problem for me building 4.8.2 for rx-elf using a 4.8.2 x86_64 host
gcc. I did not even have to rebuild the host gcc.
