built as crosses to ppc-linux hosted on i686-linux.  gcc 4.1.2, 4.2.4, and
4.3.6 don't ICE.

1: save the attached file into test-gcc47-c.c,then cd the folder contain the C
file;

2: gcc -Wall -W -Wshadow -Isrc/headers -O3 -funroll-loops -fomit-frame-pointer 
 -c -o test-gcc47-c.o test-gcc47-c.c

3:wait about 13m+, the internal error is printed.

I cannot reproduce on current trunk (195333).

Comment #1 mentioned that this was reproducible on a cross build, so my build
is on an x86_64 cross powerpc-linux-gnu configured like this:

  set X '/bin/sh' '/source/gcc/configure'   '--disable-bootstrap'
'--target=powerpc-linux-gnu' '--with-long-double-128' '--enable-targets=all'
'--with-cpu-32=603e' '--with-cpu-64=e5500' 'target_alias=powerpc-linux-gnu'
'--enable-languages=c,lto' $ac_configure_extra_args --no-create --no-recursion

My execution looks like this:

reynosa:/build/e500mc/gcc$ time ./cc1 a.c -O3 -funroll-loops
-fomit-frame-pointer  -I /tmp -quiet

real    1m31.440s
user    1m30.882s
sys     0m0.100s

Am I missing something, or has this been fixed?

I can reproduce with a gcc-4.7-20130119 cross from x86_64-linux to ppc-linux,
but not with gcc-4.8-20130120.  So possibly fixed on trunk.

Ok, so can we close this as fixed on trunk?  Or should it be reclassified as a
4.7 bug, or what?

This ICE was fixed for 4.8 by Alan Modra's "PR53914, rs6000 constraints and
reload queries" fix in r189801.  The ICE described in
http://gcc.gnu.org/ml/gcc/2012-07/msg00142.html
and the linked-to Red Hat bugzilla entry looks exactly like this PR's ICE.

The patch is localized to the rs6000 backend, but it's quite big so I would not
be comfortable backporting it en masse to 4.7 branch.
