When you add the doc changes could you also add a NEWS entry?
Note that under --branch-sim=no|yes [no] cachegrind/docs/cg-manual.xml
says:
<para>Enables or disables collection of branch instruction and
misprediction counts. By default this is disabled as it
slows Cachegrind down by approximately 25%. Note that you
cannot specify <option>--cache-sim=no</option>
and <option>--branch-sim=no</option>
together, as that would leave Cachegrind with no
information to collect.</para>
Which seems untrue now that both --cache-sim= and --branch-sim=
default to no.
Thanks,
Mark
