 I am able to work on this again.

 I tried looking at this.  It won't build cross without a bit of work,
 and the only native I can build at the moment is x86-linux which can't
 use global register variables.  So it is of no immediate help.
 
 I tried building it native on x86-linux anyways just to make sure I
 could build and run it.  I thought it wasn't working at first.  I had to
 add a 0 to the loops in bench1/bench2 before I was sure it was doing
 something.  Otherwise it took a fraction of a second to run.
 
 If you could send me a .i file and a pointer to where it was miscompiled
 that would be very helpful.  I can build a m68k-linux cross compiler and
 look at it.
 
 Otherwise, I could try compiling files with and without your gcc patch
 to see what difference it makes, but there might be too much noise for
 me to figure out what is going on.
