Locally we have had this enabled at -O1 and above to encourage testing,
but I'm thinking that for the trunk enabling at -O2 and above is the
right thing to do.
Yes.
Thoughts, comments, recommendations?
Sounds great!
It'd be nice if its framework can be re-used for
target-specific passes, doing quirky sign- or zero-extend-
related optimizations (those that are not just sign- or
zero-extend removal). Perhaps most of those opportunities
can be implemented as target hooks in this pass. Definitely
not asking for a change, just imagining future improvements.
Also, I haven't followed the thread and its branches, just
offering a word encouragement.
What kind of quirky target things did you have in mind? If there's
overlap with things we need I might be able to find someone to take it
on. Or might be able to suggest how they can be handled.
