These files are extra utility type scripts that can be used for various
purposes.

as

This is a sort of front-end script that makes lwasm look approximately like
gnu as which is useful for using lwasm as a backend to gcc.  You may need to
edit it to make it work fully.

ld

Similar to the "as" script above except for lwlink.


ar

Similar to the "as" script above except for lwar.

gcc6809lw-4.6.1-1.patch

These are patches to the main gcc source distribution for specific releases. 
The last number after the dash is a patch level for the specific patch. 
These are different to the official gcc6809 releases in the following ways. 
First, all the source for as-6809 is removed.  Also, the special "helper"
makefile and directory is removed.  Also, as of this writing, the
distribution side for gcc6809 has been down for months and the latest
release was for gcc 4.3.4 which does not build on 64 bit linux.


To use these scripts, you really need to understand how to build a gcc as a
cross compiler. The basics are that you put the as, ld, and ar scripts
whereever you plan to put your cross-development binaries. Then, when
building the cross compiler, you tell it where the scripts are.

The following work

1. Install the ar, as, and ld scripts named m6809-unknown-{as,ar,ld} in a
directory in your path, say /usr/local/coco/bin/.

2. Make symbolic links to /bin/true for similarly named nm, objdump, ranlib,
and strip in the same directory  Some of these may not be necessary.

3. Unpack gcc and apply the gcc6809 patch. The gcc6809lw* patch file
in this directory is known to work with these instructions.

4. Make sure /usr/local/coco/bin is in your PATH

5. Make sure "." is NOT in your path or is at the END of PATH. If you have
gazillions of errors pop up compiling "gemodes.c", this is your problem.

6. In a directory (other than the gcc source, say "gcc-build" at the same
level as the main gcc directory, do (assuming gcc 4.3.4):

configure --enable-languages=c --target=m6809-unknown \
--program-prefix=m6809-unknown- --enable-obsolete \
--srcdir=../gcc-4.3.4 --disable-threads --disable-nls \
--disable-libssp --prefix=/usr/local/coco \
--with-as=/usr/local/coco/bin/m6809-unknown-as \
--with-ld=/usr/local/coco/bin/m6809-unknown-ld \
--with-ar=/usr/local/coco/bin/m6809-unknown-ar

NOTE: the last three are required to prevent selection of the wrong binutils
programs at runtime.

--with-sysroot might be useful if you have a C library involved.

7. Run "make". If errors appear, troubleshoot.

8. Run "make install". Note that you will have to have your PATH variable
for "root" set up correctly if your install prefix requires root privileges.

The above is WOMM certified. YMMV.
