I have used the IACAfor nearly a month and it is great!
It help me to solve many problems that affects the performance of my code...
(and it is simple to use as long as you have the source code in hand)
However, I have noticed something strange...
Even though the analyzer has correctly identified the code for rcpss/rsqrtss,
they are treated as the same as the divss/sqrtssrespectively.(As I know,
both of the approximation instructions should run faster than the accurate
ones. However, the analyzer shows they are blocking the divider port for 14
cycles) Is it a bug or somethingelse?
Thank you for your attention!
