Recognizing Inlining & Loop Transformations
Spot how the compiler inlines functions and reshapes loops (unrolling, vectorization) so optimized assembly still maps back to source intent.
Optimizations Reshape Structure
You know common optimizations, can read optimized assembly, and reconstruct logic. Two transformations cause the most confusion: function inlining and loop reshaping.
Recognizing them keeps your reconstruction accurate.
What Is Inlining?
Inlining replaces a function call with the callee's body, eliminating call overhead.
In the binary the original function may vanish entirely; its code appears merged into every caller.
// source
static int sq(int x){ return x*x; }
int f(int a){ return sq(a) + 1; }
// after inlining f becomes: return a*a + 1;All lessons in this course
