Compiler Design — Gate Smashers [hot]

During the "Instruction Selection" phase of the compiler backend, the optimizer looks for these Phi nodes. If the architecture supports it, the compiler translates the Phi node into a conditional move or a bitwise-logic "Select" operation.

Following a playlist blindly won't work. Here is a leveraging Gate Smashers for GATE preparation: During the "Instruction Selection" phase of the compiler

The final phase maps the intermediate code to the target machine architecture. compiler design gate smashers

By using CMOV , the compiler has "smashed" the branch. The CPU pipeline never stalls because there is no jump to predict. It simply calculates the data and selects the result on the fly.
