Right, and in the cases we are talking about, the corresponding source
code is going to be more than just what can be automatically
translated.

Right, which is why the C source is not sufficient if the object code
came from an edited version of the assembly code.

It's got to be the *real* source, not just anything you put down and
say "this is the source". In the cases we are talking about, most
certainly the modified assembly still has to be completely
distributed. The question is "does the GPL require distributing the
original C code *also*?" and I see no way that saying "yes" could open a
loophole.

Sure, but I think the same of a few bit tweaks to a gif, or applying a
blur transform or... well, almost anything simple.
So in the original case, my point remains: that the .xcf really is the
source (or part of it), even if a given person happens to want to
tweak bits in the gif--and even if they in fact did tweak some bits.
