[Bug c/27815] New: ICE while building Linux kernel

[ft01 at webmastery dot com dot au]

The problem occurs with both 3.4.5 and 3.4.6. I haven't tested newer compilers,
but 3.3.6 works. Problem can be avoided by reducing -O2 to -O1. 

$ m68k-linux-gcc -O2 ice.c -c -o /dev/null
fs/ocfs2/dlm/dlmlock.c: In function `dlmlock':
fs/ocfs2/dlm/dlmlock.c:698: error: unrecognizable insn:

            (const_int 1 [0x1]))) -1 (nil)

Not reproducible with gcc 4.0.4.  The 3.4 series is no longer maintained.
