Hello,
Conditional statements such as:
int i;
if( i < 0 ) i = 0;
can be written as branchless code:
int i, sel;
sel = - (i > 0 );
i = i & sel;
The same is true for other conditional statements such as:
int i, i_max;
float f, f_max;
if( i > i_max ) i = i_max;
if( f < 0.0f ) f = 0.0f;
if( f > f_max ) f = f_max;
Question: Does the nvcc compiler automatically convert such conditionals into branchless statements?
Thanks.
