Here you go Jens
If theres a problem with i= t check the jpg from before
as i transcribed the asm
It= should be ok though

Well the thing is still to figure out how to ma= ke a functional cross compiler
from the recent binutils and gcc. I have gone through the code that I moved= from
the old 2.11/3.0 ports to binutils/gcc and it seems like I have covered it = all.

I suppose I should try to export the output from the old gcc 3.0
gcc -S Hello.c and then use that output to try to test the newer binutils a= s and
ld using the old libgcc and libc from the 3.0 port.

Could you send the Hello.S you got from gcc 3.0?

If the new binutils is working to make a functional i386-plan9 executable, = I
should focus on trying to make the new gcc compile and then test that one t= oo in
the same way as cross compiler using the old libc and new binutils, and the= n
compile a new libc using the new gcc.

I ended up in the mess of the as because I wanted to do an intermediate tes= t of
the binutils before moving on to gcc...
