Subject Re: Apache 2.0 License with LLVM Exceptions
Date Thu, 07 Nov 2019 18:21:26 GMT
You could certainly be right.  I'm not sure what part of a LLVM compiler gets added to the
output.  I think GCC has that exception not because compiler source/bytecode gets added but
because GNU-licensed compiler library code gets added to the output.  Apache Flex and Royale
have library code whose source is part of the release that gets added to the output as well.
 So if GCC/GNU really need an explicit exception, Flex and Royale might need it too.

    (IIUC, the issue isn't tool output per se, which doesn't seem like it
    would ever be covered by an OSS license, but output that includes part
    of the tool itself, whose redistribution is governed by OSS licenses.)

Adobe's EULA for Flex.   So if it turns out tool output needs explicit exceptions then we
might need them for Flex and Royale.  It could be that I've always thought of compiled output
as a translation (In fact, Royale's compiler 'transpiles' from ActionScript to JavaScript,
so not a binary output), and AIUI, translations are copyright the original owner.
