--- Comment #5 from Paul le roux <xonar.leroux at gmail dot com> --- On the GCC trunk version on godbolt.org there is still a difference between the two cases, but it seems to have turned around. The noprofile case has vector::resize partially inlined and in the profile case, it is not inlined. This makes more sense (to me at least) since I expect that certain functions won't be inlined so that one can gather better profile information. If it is the case that `--profile-generate` should be less aggressive when inlining then this bug report can be closed.
