--- Comment #9 from Thiago Macieira <thiago at kde dot org> --- I can't be certain for other architectures' performance, but my feeling is that indeed they would benefit from this. The option that was added as an -m should be an -f (and match Clang's option). However, maintainers of other architectures need to step up to help this. Aside from that, yes, this task can be closed as it's implemented.
