No switch was made. Some systems were developed with primitives in
assembly language from the start, others were developed with
primitives in some C variant from the start, and there are even
systems like PFE that do the primitives in C and then do what are
colon definitions in other Forth systems in Forth-like C code.
When was the C route taken the first time? Sometimes in the 80s, when
Forth systems were first developed on systems where C was available
and which had enough memory to make the C overhead acceptable.
Why was it taken? In Gforth we do it for portability, and I guess
that's also the motivation in most other systems with C primitives.
E.g., we tested Gforth 0.7.0 on 8 different architectures, and Gforth
0.6.2 has been successfully built on architectures (AMD64 and IA-64)
that we had never tested on before its release, and, which in case of
AMD64 were not available before its release. Compare this with Forth
systems based on (Forth) assembly language like SwiftForth or VFX,
that still do not have an AMD64 port to this day, 13 years after AMD64
CPUs became available? Or iForth, which has an AMD64 version (since
several years after Gforth), but no longer an IA-32 version
(admittedly, no big loss these days, but still, Gforth supports
IA-32).
