[Verse 1] When your program's getting heavy and the memory's running tight There's a secret in the compiler that can make your code take flight Before it hits the runtime, while it's still in source code form We can squeeze out every byte and optimize beyond the norm [Chorus] Compile time optimization, make it lean before you run Flag it, const it, eliminate what's done Link time magic working, dead code swept away Memory saved at compile time, that's the engineer's way [Verse 2] Set your flags to minus O2, let the compiler be your friend It will inline all your functions and make bloated code transcend Const correctness is the guardian of your data's sacred space Tells the optimizer clearly what can move and what stays in place [Chorus] Compile time optimization, make it lean before you run Flag it, const it, eliminate what's done Link time magic working, dead code swept away Memory saved at compile time, that's the engineer's way [Bridge] Dead code elimination sweeps the unused functions clean Link time optimization sees what runtime's never seen Whole program analysis finds the fat that hides within Strip away the excess weight before your app begins [Verse 3] Template specialization cuts the generic overhead down Function inlining eliminates the call stack running around Static analysis revealing what your program really needs Trimming every allocation while your binary succeeds [Chorus] Compile time optimization, make it lean before you run Flag it, const it, eliminate what's done Link time magic working, dead code swept away Memory saved at compile time, that's the engineer's way [Outro] Before the first instruction runs Before the heap allocates Your compiler did the heavy work Optimization never waits
