            Bug ID: 57929
           Summary: gcc-4.8: FTBFS on m68k: ICE compiling
                    libjava/interpret.cc
           Product: gcc
           Version: 4.8.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: java
          Assignee: unassigned at gcc dot gnu.org

original preprocessed source code

Hi,

this is a forward for http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=711558
which is an ICE trying to bootstrap gcj-4.8 that I *think* remember seeing for
gcj-4.7 (but not gcj-4.6 which works fine) already too, on the Debian/m68k
Linux 3.x (NPTL, atomics via syscall) platform.

The problem is now that the gcj part got merged into the main gcc source
package and this is kinda holding up our entire toolchain update (also, I think
gcj-4.6 got removed from sid).

Since I was unable to get OpenJDK/zero working either, gcj is our only hope to
keep Linux/m68k spinning so I’m hoping that $skilled_people will have a look at
it.

Preprocessed source attached here, too (xz compressed, hope that’s ok).
