--- Comment #16 from Andrey Belevantsev <abel at gcc dot gnu.org> 2011-04-27 08:10:12 UTC --- The patch from 4.5 can likely be ported to 4.4 somewhat easy, however, it is big enough and I am not sure that there will be any more releases off 4.4-branch. If there is such a need of having this in 4.4, and if there will indeed be another 4.4 release, I can do the porting.
