[PATCH] profiledbootstrap

[PATCH] profiledbootstrap

[Andreas Krebbel]

Hi Jan,

profiledbootstrap still does not work (at least on i386 and s390) due to
PR 14684. The patch proposed in the PR by Kelley Cook was not applied on mainline.

I've limited the patch to enable only -funroll-loops as you suggested in the PR. 
With the patch applied profiledbootstrap survives on i386 and s390.


OK?

Bye,

-Andreas-
