The specific discussion was about the LLVM compiler backend,
that VSI use for their compilers. If VSI made that available (it is open
source) then it would be easier for people to write or port new
compilers using LLVM as backend.

 A key point about LLVM (and the reason why Apple, for example, has
embraced it and gone away from GCC) is that it is not copyleft. So
companies can use it and adapt it and redistribute it, with no obligation
to open any source. They are free to take without giving back.

LLVM is under a permissive license, so VSI does not have
a legal obligation to release their changes.
We are arguing that it would be good business for VSI
to release their changes.
