--- Comment #16 from Robin Dapp <rdapp at gcc dot gnu.org> ---
Thank you!

I'm having a problem with the data, though.
Compiling with -Ofast -march=3Dznver4 -mtune=3Dznver4 -flto -fprofile-use=
=3D/tmp.
Would you mind showing your exact final options for compilation of e.g.
pbeampp.cc?

I see, similar-ish for both commits:
pbeampp.c:119:8: error: number of counters in profile data for function
'primal_bea_mpp' does not match its profile data (counter 'arcs', expected =
20
and have 22) [-Werror=3Dcoverage-mismatch]

output.c:87:1: error: corrupted profile info: number of executions for edge=
 3-4
thought to be 1
output.c:87:1: error: corrupted profile info: number of executions for edge=
 3-5
thought to be -1
output.c:87:1: error: corrupted profile info: number of iterations for basic
block 5 thought to be -1=
