You may be interested in this (rough) article I came across:
http://liw.iki.fi/liw/misc/hh-blurb.pdf

It describes an in-house implementation of a programming language
(Lisp dialect) for embedded use.

An interesting quote (p. 26):

"... The C implementation was done in two stages. First, the Python
implementation was rewritten in Python, but using constructs that
would easily map into C. For example, simple garbage collection was
implemented, and data structures were simple arrays, rather than
Python's lists or dictionaries. Using Python for the first stage of
the rewrite made it easy to experiment with various approaches and to
find abstractions that fit C and worked well. The rewritten Python
code was then translated by hand to C."
