[kaffe] Porting Kaffe-1.1.4 on mips lx4189

This may have nothing to do with your problem, but
note that the Lexra processors aren't really 100%
MIPS compatible - they don't implement the "load
left" and "load right" instructions used to handle
unaligned (typically, packed) data. Unless the OS
knows to emulate those instructions, or the compiler
is told to avoid emitting them, you could get the sort 
of behavior you describe.

        Hi everyone,

        I'm always trying to use Kaffe 1.1.4 but it's seems to be impossible to run 
        it on a Lexra Mips lx4189 processor.

        kaffe compile ok with:

        ./configure --target=mips-linux --host=mips-linux --build=i386
        --prefix=/usr/local/kaffe --program-prefix=mips-kaffe-
        --enable-shared --disable-static --disable-gcj --enable-debug
        --disable-mips2 --disable-alsatest --disable-esdtest --disable-sound
        --disable-xprofiling --disable-xdebugging --disable-feedback
        --disable-nls --without-jikes --without-profiling --without-stats
        --without-x --without-awt --without-alsa --without-esd
        --with-engine=intrp --enable-pure-java-math

        I would like to run OSGI but if a simple class doesn't work...
        It gives me the following error at the rate once every about five times. 
        It tries to execute the instruction not supported in lx4189.

        # java Test01
        unknown instruction executed at 2ad9eff8
        unknown instruction executed at 2ad9eff8
        unknown instruction executed at 2ad9eff8
        unknown instruction executed at 2ad9eff8
        unknown instruction executed at 2ad9eff8
        The message displays it continuously.

        It failed as shown the following occasionally. 

        # java Test01
        Internal error: caught an unexpected exception.
        Please check your CLASSPATH and your installation.

        does any body have an idea about it?
