I don’t know what you’re trying to say here but it’s completely irrelevant
to what I said. There is within the GPLv3 which states if you extract the
ir from gcc in some way the resultant ir is gplv3. Like I said, see the
faq.

I’m on mobile so I’m not going looking for this stuff.

Of course it does, every compiler builds up an AST IR prior to lowering to
another IR. GNAT doesn’t use a symbol table, everything is in the tree.
