Ok. Agree. I never used to use %function when I wrote assembly
functions earlier. I am sure a lot of code will break if this was
enforced.
If you've not used %function on ARM, then your code is semantically
broken even if it isn't syntactically broken.
The ABI rules for dealing with interworking and and out-of-range
branches all rely on %function being used correctly.
Hmm.. I learned it the hard way:)
BTW, very few assembly functions in U-Boot had %function or equivalent.
I am trying to clean it up at least for armv7.
Thanks,
