The 10.1.2 update finally has a math library written in assmebler.

I timed sqrt() to be six times faster than 10.0 - 10.1.1. Now it is the same speed (or slightly faster) than 9.2.2.

Yeah ;->

This will speed up rendering programs, etc. You don't have to link to LibMoto to gain speed anymore!

Cool! Do you know if the source code is available? It would help me a lot because I'm writing a compiler and don't want to reinvent everything

I don't believe so, but you shouldn't need it anyway. You don't want to staticly link in such functions, if you want to have any hope of running on Mac OS X across versions and making any system calls your going to need to be able to dynamic link anyway.

I'm just interested in how the pro's write code, so I could learn something. I love writing assembly and working out the fastest way to do something.

Same here. 6 times faster is quite a jump. ;-)

Louis, is the 6x figure accurate? What kind of operations in common-use will be accelerated by the new math lib? For instance could the less-than-stellar CPU usage of iTunes be due in part to the old math lib?
