If we are still going to need it soon I think it is fine to leave it
like this.

I left this lying around because there is another legalization pass
coming up that should cause the same post-lowering optimization passes
to be executed if progress is made.  I can clean things up though if you
like, and re-introduce the reset of the progress flag in the future
commit.

If you didn't do this in the previous patch, then maybe do it here:

if (OPT(lower_regioning)) {
   ...
}

and avoid resetting progress.

2018-12-29 Thread Francisco Jerez
It's redundant with the functionality provided by lower_regioning now.
