Whoops, thanks for the heads up.
I'm testing this fixed version.
Please start a new thread for every new patch (series). I missed this
one like this, instead I reviewed the older one.
Is it really best practice. My impression is that patch review (iterating over
a patch) happens in the same thread (in most cases). It's caused by discussion
in between sender reviewers.

Meh :) If I need a reply to somebody's questions, I always attach patch as an
attachment.
And I can't likely influence how Thunderbird is going to mark it.
Don't encode as non-text. Don't use x-anything if you can help it, it
is meaningless in email.
Use git send-email, it makes everything work :-)
I know.
Anyway, sending updated version of the patch.
Cheers,

Subject: [PATCH] rs6000: Remove unnecessary option manipulation.
gcc/ChangeLog:
* config/rs6000/rs6000.c (rs6000_override_options_after_change):
Do not set flag_rename_registers, it's already enabled with
EnabledBy(funroll-loops).
Use EnabledBy for unroll_only_small_loops.
* config/rs6000/rs6000.opt: Use EnabledBy for
unroll_only_small_loops.
