Thanks for the explanation. Understood the root cause and that's reasonable.

So, do you have plan to fix this (i.e. to separate the FP and integer types)?

I want to enable the new costs for Ampere1, which is similar to N2's
issue-info.  If this problem won't be fixed in the near future, I think a
workaround is probably to adjust the general_ops in the issue_info.  E.g. set
the general_ops of both scalar and vector to 3 instead of current values of "4
and 2".
