Author: lattner

New Revision: 150065

URL: http://llvm.org/viewvc/llvm-project?rev=150065&view=rev
Log:
No actual functional change here, just some clarifications:

Clarify that contributors are agreeing to license their code under the 
license corresponding to the subproject that they are contributing to,
as requested by a potential contributor.

Also, as a drive-by, update the llvm-gcc/GPL section to mention dragonegg
and say that GPL code is all in its own repo's.
