Right.

That's a really strange view. First many bugs are fixed from version to
version and the code being generated is always going in the right
direction. And since you noted that in another thread there is a huge
set of bug fixed since 3.11p in GNAT GPL 2013. The backend (GCC) has
also been updated many times since then and is generating lot faster code.

That's plain wrong. And almost an insult to the people who have
development the compiler since all those years!
