Larry McVoy scripsit:
At Sun this was called "make bootstrap" but
I bet that predates Sun. The
bootstrap process, as I remember it, had the compiler build the compiler,
then the new compiler built the kernel and userland, then there was an
install step, and presto, you were running on bits you had built yourself.
All of them.
Well, provided the compiler is honest, contra Dennis.
An interesting fact about the Squeak Smalltalk image (which runs on the
Squeak VM as well as other VMs) is that there are bits in it which were
set prior to 1980, and consequently are not the consequence of any of
the source code provided with it.
