--- Comment #28 from Segher Boessenkool <segher at gcc dot gnu.org> ---
For Q111: on rs6000:
;; Combiner totals: 53059 attempts, 52289 substitutions (7135 requiring new
space),
;; 229 successes.

I don't have C++ cross-compilers built (those are not trivial to do, hrm). 
I'll
try to build a s390x one.
