At some point it's removed (see bfin, avr32 removal etc...). Except if there is someone that really want to keep it and help us to take care of this support. There is a similar issue with ppc w/ SPE that was deprecated in gcc 8 and removed in gcc 9: https://git.buildroot.net/buildroot/commit/?id=96e80ad214ced86c802d561946fa7da88c1595eb Should we keep indefinitely gcc 8 for ppc w/ spe ? Yes and no because we know that ArcturusNetworks people (maybe other) are still using ppc w/ spe and they have sent patches for arcturus_ucp1020_defconfig. But gcc-8 is not maintained anymore.
