Hello,
-fbranch-probabilities fails to find the gcda information, because they
are initialized only if flag_profile_use.
The problem is easily observable by recompiling with
-fbranch-probabilities instead of -fprofile-use (after profile
information generation)
This fails with "xxx.gcda not found, execution counts estimated".
This trivial patch fixes it. testsuite ok.
OK ?

flag_profile_use.
