--- Comment #10 from David Binderman <dcb314 at hotmail dot com> ---
I am not so sure this one is fixed.
I have this code:
__attribute__((__cold__)) a();
b() { a(); }
c() {
b();
if (d())
e();
}
derived from Linux kernel and it does this with revision 250361:
during GIMPLE pass: profile_estimate
bug368.c: In function ‘c’:
bug368.c:7:1: internal compiler error: in to_reg_br_prob_base, at
profile-count.h:189
}
