--- Comment #417 from John Paul Adrian Glaubitz <glaubitz at physik dot fu-berlin.de> --- I haven't been able to find any regressions. Thus, my suggestion would be to clean the patches up now and get them merged if that's okay. This would expose the patches to a larger audience and help them get tested more thoroughly. Also, Jeff Law could pick them up for his GCC weekly(?) tests.
