So confused

Hello,

I am trying to bring the port for m68k palmos upto date with gcc version
3.3.  First I started by looking at the changes made to gcc version 2.95.x.
That's when I noticed that the attribute system between 2.95 and 3.3 are
completely different.  I scratched my head, and started to search the
internet for more information, I have found a lot of information that will
require a lot of reading.  So I went back to the drawing board.

I compiled a cross compiler for the m68k-elf target.  That was pretty easy
once I found the proper information.  I then compiled a test program I had
from gcc version 2.95 to see what real changes there was.  The biggest
change was to call PalmOs functions requires a 'trap' instead of a 'bsr'.

So right now I still have several options. I can modify gcc to produce a
'trap' instruction for calls to PalmOs or I can produce a PalmOs library,
that would have all of the correct calls in it.  So, for whatever reason I
decided to modify the gcc code.  I did a grep for 'bsr' in binutils and the
gcc code.  In binutils/m68k-opc.c I generated a patch to replace all 'bsr'
instruction with 'nop'.  To try an understand what I needed to do.  Well
binutils compiles ok, but gcc-core no longer compiles.  So I threw out that
patch.  I generated a patch for gcc/m68k.md to replace all define_inst for
"jump" or that use 'bsr' with a nop.  At this point binutils/gcc-core/and
gcc-3.3.1 all compile.  The patch is only placed into gcc-3.3.1 not
gcc-core.  When I look at the assembly listing of my file I still see 'bsr'
instructions.

So could someone please tell we what I am doing wrong?  I am sooo confused.
Thanks.
