Which is why I hoped my patches for uComplex were permissible, since it
adds 'const' to make the compilation more efficient and sets the calling
convention to 'vectorcall' for Win64, something that the compiler won't
think to do unless explicitly told so, and maybe a slight incentive to
improve the compiler as far as vectorisation is concerned (and complex
numbers are a good candidate since for most basic operations, the
components are modified in tandem).
Well, I can't comment on this, in such matters I trust Florian knows what he is
I guess adding 'vectorcall' and 'const' are micro-optimisations, but I
see it more as refactoring and good coding practice in the case of
'const', while 'vectorcall' is more about knowing what kind of data
you're dealing with.
I would not argue in the case of const and apply where appropriate,
I don't know enough about vectorcall to comment.
Maybe the patch can be split into parts so const can already be applied.
It's not the first time we must advise to keep patches small and focused.
Although I am also often a sinner when it comes to mixing things in a
patch. When you're in the flow of things, that's the last thing on your mind :/
