            Bug ID: 58215
           Summary: -fwhole-program cause gcj undefined reference to
                    `Main::class$'
           Product: gcc
           Version: 4.8.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: java
          Assignee: unassigned at gcc dot gnu.org
          Reporter: pj at csc dot fi

test file to compile

/v/linux212_x86_64/lang/gcc/4.8.1/bin/gcj  -pipe -Wall -O3 -fomit-frame-pointer
 -ffast-math -fprefetch-loop-arrays -fwhole-program -march=core-avx-i -mavx
-mtune=core-avx-i --main=nbody nbody.java -o nbody.gcj -lm
/tmp/ccmUUeIk.o: In function `main':
:(.text.startup+0x13): undefined reference to `nbody::class$'
collect2: error: ld returned 1 exit status
I tested also compiler version 4.8.0

without -fwhole-program it works.
Operating system is RHEL6.

By the way  ecj[1] was missing when ../gcc-4.8.1/configure
--prefix=/v/linux212_x86_64/lang/gcc/4.8.1 --enable-threads=posix
--enable-checking=release --enable-__cxa_atexit --disable-libunwind-exceptions
--enable-libgcj-multifile --with-mpc=/v/linux212_x86_64/appl/math/mpc/latest

-v output:

 /v/linux212_x86_64/lang/gcc/4.8.1/bin/gcj -v  -pipe -Wall -O3
-fomit-frame-pointer -fwhole-program  -ffast-math -fprefetch-loop-arrays 
-march=native --main=nbody nbody.java -o nbody.gcj -lmUsing built-in specs.
