--- Comment #29 from Jakub Jelinek <jakub at gcc dot gnu.org> --- The port is not actively maintained and contains estimated 75%-80% of dead code. The rs6000 backend had since the split around 290 commits that didn't touch the powerpcspe backend, if we just assume that only 20% of those are relevant to powerpcspe too (hard to judge exactly because the dead code from there isn't removed), then that is still significant number of known issues in the port. The announcement of the intent to obsolete the port has been posted already more than a year ago, if you look in the comments in this PR, you'll see numerous pings, despite which no (significant) action has been taken. GCC backends need active maintainance, including regular testing, reporting regressions and fixing those, otherwise they are only significant burden to other maintainers and not really useful to users.
