--- Comment #1 from Steinar H. Gunderson <steinar+sourceware at gunderson dot no> --- Created attachment 14028 --> https://sourceware.org/bugzilla/attachment.cgi?id=14028&action=edit Proposed patch I've taken a stab at a fix. I wonder if it's overly conservative, ie., we will never need the fallback, but it should at least be reasonably safe. I've verified that the slowdown disappears when applying it. -- You are receiving this mail because: You are on the CC list for the bug.
