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 will
probably need to edit it to make it work fully. Simply put this in place
of whatever gcc6809 installed for "as" (in the "m6809/bin" folder in
"--prefix") after editing it to point to the real location of the "lwasm"
binary.


ld

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


ar

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


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.

You should probably name them m6809-unknown-none-{ar,as,ld} or similar
depending on your gcc build target. Then you'll want to get the gcc6809
patch and patch the correct gcc source code. Then use a configure line
similar to the following:

configure --enable-languages=c --target=m6809-coco
--program-prefix=m6809-coco-lwos- --enable-obsolete
--srcdir=/home/lost/gcc6809/src/gcc-4.3.3 --disable-threads --disable-nls
--disable-libssp --prefix=/usr/local/coco --with-as=/usr/local/coco/bin/as
--with-ld=/usr/local/coco/bin/ld --with-sysroot=/usr/local/coco

Obviously adjust various paths to match what you're doing.

The exact mechanics of configuring and getting gcc to install correctly is
left as an exercise to the dedicated masochist.
