--- Comment #18 from anlauf at gcc dot gnu.org --- (In reply to Jürgen Reuter from comment #17) > How would I set up such a bisection for the n git commits between June 12 to > June 19? Unfortunately, I cannot really get a small reproducer .... I didn't mean that. I meant doing a bisection on the .o files of your code. But given that you have isolated a procedure, that is not necessary. You could try to defeat optimization by using a temporary v0 for v and declare it as volatile. Would be interesting to see if that makes a difference.
