The meaning should be clear, "fp" is a floating point instruction, "simd" a
SIMD one
as defined in ARM-ARM.
Indeed, I had to add the Y for the f_mcr insn to match it with nosimd.
However, I didn't feel that it should be moved to the right, since it's
already disparaged. Am I missing something detail?
It might not matter for this specific case, but I have seen reload forcing the
very
first alternative without looking at any costs or preferences - as long as it
is legal.
This suggests we need to order alternatives from most preferred alternative to
least
preferred one.
I think it is good enough for commit, James?
Methinks that my issue with those attributes is that I'm not as fluent
in AArch64 as I'd like to be.
Please, feel free to edit the patch changing the order then.
Thank you,
