That's the source of this LLVM binding, the compiler and runtime come from =
FSF and are under GPLv3 with linking exception.=20

Then there's LLVM which actually generates the final code. The compiler lin=
ks to the LLVM-C lib to generate an in memory AST which generates the LLVM =
IR which is then passed onto the LLVM tools, as/ld.

So, I think you could argue that the final code is a combination of GPLv3 w=
ith LE (the runtime) and whatever licence you want (your code).

into FSF GNAT's source tree so that it has FSF's RLE permission grants?  On=
ly AdaCore can answer that question.

AdaCore staff on IRC said "you'd be surprised" when I asked about licensing=
 for this ages ago, hinting that it wouldn't all be covered by GPLv3 (no LE=
).
