There's patch that does that.
Patch can bootstrap on x86_64-linux-gnu and survives regression tests.
Ready to be installed?
Thanks,

Is the change of type of freq_sum intentional? Even with this patch,
all the callers will keep passing their frequency sums as ints and so
the implicit conversion seems a bit misleading.
I guess complete transition to sreals would include also switch from
using cgraph_edge::frequency to sreal_frequency in
get_info_about_necessary_edges and users of struct caller_statistics.
Hello.
All right, I'm leaving that to you Martin ;) You are much more familiar
with the code base.

I planned to work on conversions to sreals right after resolving various
exchange2 issues and I can still do this bit afterwards, but the change
in the parameter type looks like you wanted to but eventually did not?
Thanks,
Martin
