+1 from me on the general principle that if LLVM accepts a name then config.sub should know about it, and map it to an existing GNU name that means the same thing, if any. > For what it's worth, we could imagine someday something like > --std=2024 to have versioned normalizations, allowing packages to opt > into doing the opposite normalizations If you want to work on this, I suggest that your first step should be to try to make config.sub and config.guess as table-driven as possible. Right now, adding *any* sort of alternative mode for output is going to be an exercise in frustration, since both scripts are big balls of mud (in the classic sense of that term -- http://www.laputan.org/mud/mud.html). Given the extreme limitations of portable shell scripting, this may only be possible if you convert them to be generated from a more flexible source. zw
