RE: x86 Bisect script is currently down
The script is back online for now. But still with some issues on automation due to the machine config after crash. I will run the script on at least a daily basis for a temporary solution. Thx, Haochen From: Jiang, Haochen Sent: Wednesday, May 14, 2025 10:51 AM To: gcc-regression@gcc.gnu.org Subject: x86 Bisect script is currently down Hi all, During my vacation last three weeks, it seems to me that my bisect script is down. After I am back from my holiday this week, I found that the machine OS disk is totally down. Please expect some time to bring that bisect script back. The Test regression reporter is still running. (However, with quite a few false positive for a long time due to timeout issue and hard to fix unless I found other powerful machines.) Thx, Haochen

This is just an extra inlining which causes pcom to happen twice now.
Will look into fix that this coming week.

The specifics_1 failure is a front-end bug which is being fixed:
