No. David Wheeler's dissertation goes into that in detail. Sixty pages of
detail. https://www.dwheeler.com/trusting-trust/dissertation/

(As an aside, the people who bring up this compiler trust issue seem not to
have thought about how it could work in the modern world. We have several
compilers with open source and long version histories these days, and ditto
operating systems.)
