Another interesting question is whether the currently shipping
version
of a language written in itself was compiled using the same version
of
itself or the previous version. I recall HP compilers generally being
built with the previous version (at least the last time I looked
which
was probably in another century).
GNAT itself was written in Ada from the beginning, though the backend
is part of gcc so partly rewritten to support some Ada constructs
(which also benefitted C++).
From the beginning I believe they used the Alsys
compiler until
GNAT was able to compile itself.
