Hello.
I noticed there are quite many selective scheduling PRs:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=84872
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=84842
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=84659
and many others.
I want to ask you if you plan to maintain the scheduling?
Yes. The current status is that I have patches for 83530, 83962, 83913,
83480, 83972, 80463. I don't have patches for any of the 84* issues.
I'm planning to submit the patches for the former set and to look at the
later set next week.
Nice!
Maybe we can create a meta bug to track all sel. scheduling issue.
May I create it?
I usually do most of the work by myself after internal discussions with
Alexander and other colleagues here, and there might be delays when I get
busy with unrelated stuff. However, if there's a pressing need, we have
enough knowledgeable people to fix any sel-sched PR within a week or so.
Is it enabled by default for any target we support?
Yes, ia64 at -O3. The testing we make usually is like follows: bootstrap
and test on ia64, bootstrap with sel-sched enabled on x86-64, and make any
new tests from PRs be run on x86-64, ia64, and ppc. This way I'm confident
that it mostly works on that platforms.
Great.
Should we deprecate it for GCC 8?
No, I don't think so.
Works for me.
Thanks for clarification.
Martin
Best,
Andrey
Thank you,
