Oh whoops, sorry about that and not replying to the list.
I'll try not to screw up. Generally I think Double is preferred because
then everything uses SSE2 and no awkward ferrying of data between it and
the floating-point stack is required (come to think of it, only Win64
actually requires the presence of SSE2 and refuses to install if it's
not present).
Given that Florian prefers a node micro-optimisation for functions like
floor, it should be easy enough to check if the input is of type Single
or Double, and drop out if it's Extended (falling back to the actual
source code).
Well, in case of a node optimization in combination with inline I do not
see it as a real micro optimization as it results in the best code which
is not the case if it is ifdef'ed assembler code in a unit which is most
of the time not used (fpc x86-64 rtl is build with -Cfsse2 normally).
