writing custom machine descriptions

[Danish Samad]

hello,

We have designed our own processor. In order to
generate assembly instructions for the desired
architecture will I have to add machine description
files (as has been done in gcc's config directory)?
Or will I also have to modify the gcc backend as well?

regards,
danish
