I don't believe there is such a place. The developer policy is to reject them: `The LLVM project does not accept contributions that include in-source copyright notices...` (more below).

I think that's the "vendored dependency" bit from the developer policy: `...except where such notices are part of a larger external project being added as a vendored dependency.`


CC @llvm-beanz @rnk as LLVM Foundation folks; the foundation handles all the legal questions, so it's really up to them.
