--- Comment #11 from Jack Howarth <howarth.at.gcc at gmail dot com> --- (In reply to Jakub Jelinek from comment #10) > Also, benchmarking -O0 code is weird. Is gcc really optimizing that low by default? Certainly it is at least doing -O1 when not passed a -O* optimization flag? In any case, shouldn't the optimization be somewhat orthogonal to this problem since, by normalizing to the one process timing, we are just looking at the effect of the overhead in the processes?
