So, after having reviewed it, my major comment is that it appears that
the initial patches introduce a bunch of stuff that could cause aborts
at runtime due to NOT_REACHED(), and then the later patches fix those up
one by one. I don't really like that kind of approach, because it means
that the intermediate commits are buggy.
I'd suggest one of two approaches:
- Fold together all the commits from the point where the
NOT_REACHED()s are introduced to the point where they are
fixed.
- Instead of breaking up patches by area (e.g. decoding,
encoding, formatting, parsing), break them up by instruction
(e.g. one patch for Clear-Actions, one for Goto-Table, and so
on).
Normally I'd insist on the latter but this stuff appears pretty
straightforward so I don't think it's a big deal.
