3.4.0 on linux-alpha: Bug with FDO

[Kurt Garloff <garloff at suse dot de>]

Hi,

brand new 3.4.0 on my linux-alpha fails when trying to use feedback
driven optimization:

garloff@pws:~/C/ljapunov [1]$ rm lja_speed.gc??

 -fomit-frame-pointer -fschedule-insns2 -O3 -frerun-loop-opt -mcpu=ev56 \

 -fprofile-generate -s lja_speed.c /usr/lib/libffm.a -lm
