That sounds like a good idea to me :)
Using -O0 and -fprofile-generate triggers yet another problem. The
module gets a constructor function registering the profile info and
TARGET_OPTIMIZATION_NODE is not set for it (because it is built after
free lang data). This eventually makes ipa-cp to think that the function
is compiled with -O2 (because WPA is invoked with -O2) and ICE again.
I am testing the following:
