How Compiler Register Allocation Uses Interference and Spilling
Register allocation assigns live intermediate values to CPU registers, building interference constraints and spilling selected values to memory when registers run out.
-
Static Single Assignment Form and Phi Functions
How SSA gives each value one definition, while φ-functions merge control-flow paths so compiler optimizations remain correct.
-
Compiler Escape Analysis and Stack Allocation
How compilers follow object references to decide whether an allocation can stay in a stack frame or must be managed on the heap.
-
Rust Monomorphization and Static Dispatch
How Rust generates type-specific code for generics, and why that improves call performance while increasing build time and binary size.
-
Static Single-Assignment Form and Phi Nodes
SSA gives each intermediate value one definition, while φ-nodes merge values from different control-flow paths for simpler data-flow optimization.
-
How Linkers Resolve Symbols and Relocations
How linkers turn object files into runnable code by matching symbols, fixing addresses, and coordinating position-independent code with shared libraries.
-
Compiler Escape Analysis and Stack Versus Heap
Escape analysis predicts whether a value can outlive its function, guiding stack or heap placement and influencing allocation and garbage-collection costs.
-
Static Single Assignment Form and Phi Nodes
How SSA gives every assignment a distinct version and uses phi nodes to merge values when control-flow paths meet.
