What is branchless computing?
What will be an ideal response?
If branches are considered harmful because a misprediction can lead to bubbles in the pipeline, it is a good idea to
reduce the frequency of branches. Doing this is called branchless computing. In particular, it refers to predicated
computing where an instruction is conditionally executed; for example, the ARM’s ADDEQ r0,r0,#1
increments the value of register r0 if the result of the last operation that set the condition code was zero. The
IA32 MMX instruction set extension also permits branchless computing by turning a condition into a value; that is, if a test yields true, the value 1111…1 is generated and if the condition is false the value 0000...0 is generated.
These two constants can then be used as masks in Boolean operations
