</span></span></span><![endif]><span lang="EN-US">When using mathematical functions like powf or sqrtf, I need to use __nv_powf and __nv_sqrtf from libdevice. This works fine but unlike powf, expressions like powf(x, 0.5f), where .5f is constant are not optimized/strength
reduced.<br>
Is there any way to call powf, then optimize then rename these calls later on (and probably optimize again…)? Or is there a better approach?<o:p></o:p></span></p>
