Yes... The assembly for wo_prof_mult_field_peeling.c looks "unrolled".

But I have number of question to you. Why are you running
wo_prof_mult_field_peeling.c with profiling? At least, it was not intended to
be executed this way. If it is, then it is a bug in struct-reorg.exp. 

The other question is whether the failing tests that should run *with*
profiling, like w_prof_gloval_var.c and w_prof_local_var.c, fail after
compilation with -fprofile-generate or after second compilation with
-fprofile-use. 

Thanks a lot for debugging,
Olga
