Hi, Wilco.
It looks good to me, but FCMP is quite different from FCCMP on Exynos M1,
so it'd be helpful to have distinct types for them. Say, "fcmp{s,d}"
and "fccmp{s,d}". Would it be acceptable to add this with this patch or later?
It would be easy to add fccmps/d as new attributes, I prefer to do that as a
separate
patch. Are there any other attributes that you think are missing besides the
ones I know
about (extr, 64-bit mul/mla, mulh, bfi)?
Also would we need a new entry in the cost tables?
Hi, Wilco.
I don't think that additional entries in the cost tables are needed.
However, I'm afraid that, other than the ones above, no, or perhaps a
handful of, additional attributes will be needed. The reason is that,
so far, I have found few attributes that would make a noticeable
difference. As more performance analysis, a never ending task, is done,
I expect some important attributes to pop, but I cannot anticipate them
conclusively right now.
Thank you,
