If the branch isn't usable as-is on LoongArch (which apparently is the state at present), there should be no problem with any backport to architecture-specific code, regardless of how large it is - it can't exactly regress from "not usable". I note that the only GCC target supported for LoongArch is loongarch*-*-linux*, so there isn't really a question of being usable for bare-metal either. -- Joseph S. Myers joseph@codesourcery.com
