You should not ask legal questions on a public mailing list like this - 
nobody here is your lawyer. It's not uncommon for these discussions to 
end up being a waste of time and attracting lots of stupid comments from 
people who have different views.

Having said this - I'll bite once and hopefully help

#1 Why on earth the Apache license? LLVM doesn't currently use it and 
doing so would make anyone in the llvm community using those changes 
basically impossible. (Some may, but that's their choice)

#2 You can't change the license on code you don't own the copyright. For 
modified files - I guess you could mix license them (very ugly) and the 
end result would be the most restrictive combination of terms. This is 
really really a lawyer question - SFLC and others do give pro bono 
advice to projects. I'd recommend to contact them

#3 For totally new files which you are the full copyright holder - You 
can slap on whatever license you want - assuming it's compatible with 
the surrounding sources/package. etc.

If I had any vote in this - I would hope that you use the same license 
as the rest of the sources. If that doesn't work - maybe contact a legal 
professional to see what other alternatives exist.

Contact me off list if you need SLFC or similar open source legal contacts
