I could say a lot more... I thought I'd let you drag any other
details you wanted out of me. :-)
My idea was to initially just check for any not obviously safe
changes, and later in the project try to

We saw a 41% speed-up for SimpleText, a 110x peak speedup for
and (cstdlib). A C++ Carbon hello world was 91x faster,
peak. C hello world was the same speed. Peak speedups for C 2x,
for C++ 142x.
Cool! After some measurements (-ftime-report, tee, gre

Sounds like a multi-person, multi-year project.
We did something like this a while ago, called the compile server.
The idea was to be able to advance through unchanged portions of code
