--- Comment #9 from Stefan Schulze Frielinghaus <stefansf at linux dot ibm.com> --- It looks like as if the first fix didn't entirely solve the problem. It turns out that the normal form of const_int is not always met. Before releasing a new patch, could you test it first in order to make sure that I do not break bootstrapping again. I already gave it a try against the reproducer but would like to make sure that the whole bootstrap is successful.
