Is that true, though?  GCC can produce not only GIMPLE trees but also
various forms of annotated RTL and dump them to files.  I believe that
it also accepts some of these representations as input.  Is it
possible to stop people from writing nonfree tools that use those
representations of programs?  I don't see how, unless you write a
Microsoft-style EULA that restricts use as well as distribution.  Ie,
people can write non-free assemblers that use the assembly output of
GCC, people can write non-free compilers that target the gas assembly
language, and so on, all in conformance with the letter of the GPL.

What am I missing?
