Awesome! What triplet did you use, is it “powerpc9-linux-gnu”?
I’d like to change the patch so that it doesn’t affect other targets.
Would the updated patch below work for you?
Could also you succinctly explain why this flag is needed? I’d rather
have a comment in the code so the next person that fiddles with it knows
why it’s there.
Thank you!
Ludo’.
