CGEN-generated files vs GPL

[DJ Delorie]

What are the implications (GPL-wise) of using CGEN-generated files in
gcc?  Specifically, I'm working on a second attempt to contribute the
MeP port, and its intrinsics are CGEN-generated (and there are a *lot*
of them - most opcodes have an intrinsic).  I'd rather not have to
manually enter all that info twice (there are VLIW tags, latency info,
etc - for each intrinsic)
