[x265] Size vs. speed

[dave]

Steve and Min or anyone else with an opinion,

For many of the primitives that I have submitted I unrolled loops with 
%rep to improve performance but for nested loops I only unrolled the 
inner loop leaving the outer loop intact.  For my last submission, 
interp_4tap_horiz_pp/s, it is entirely unrolled with %rep, as is the 
sse4 version, though in a different way.  This probably generates 
considerably larger executables, especially for the larger sizes.  Is 
there any preference on this?  Are x265's goals purely performance 
related over memory usage?

thanks,
Dave
