Loop Invariant Code Motion optimizes performance by moving code that computes the same result in each iteration of a loop out of the loop. This reduces the number of instructions executed within the loop.

Inline Expansion replaces a function call with a copy of the function's body. This reduces overhead from function calls but can increase the size of the executable if used excessively.

Peephole Optimization is a method of improving the performance of the generated code by making local changes to small sections of the code. It can include eliminating unnecessary instructions and simplifying expressions.

Data Flow Analysis is a technique used by compilers to gather information about the possible set of values calculated at various points in a computer program. It's a fundamental tool used in many optimizations to ensure correctness and efficiency.

Common Subexpression Elimination is an optimization technique that identifies and eliminates redundancy by computing an expression once and reusing the result rather than recomputing the expression.

Register Allocation is the process of assigning a large number of target program variables onto a small number of CPU registers to make program execution faster and more efficient. It's crucial for optimizing performance, as it reduces memory accesses.

Basic Block Partitioning involves dividing a program into blocks of instructions with no branches in except to the entry and no branches out except at the exit. It's used to facilitate optimization, as each block can be optimized separately.

Strength Reduction replaces more expensive operations with less costly ones, such as transforming multiplication into addition. This typically occurs in looping constructs and can significantly improve performance.

Code Factoring involves identifying common sequences of instructions or subroutines and creating a shared function that can be called multiple times, therefore reducing the generated code's size and improving maintainability.

Control Flow Graph Construction is the process of representing a program's flow of control using a directed graph. This helps in understanding the program's structure, optimizing control flow, and identifying loops, unreachable code, etc.

Instruction Selection is the process of choosing the appropriate machine instructions to implement the semantics of the source program. It's vital for the correct translation of operations and affects the efficiency of the generated code.

Constant Folding is the compile-time simplification of constant expressions. It pre-calculates constant expressions to save computation time during program execution.

Dead Code Elimination removes code that does not affect the program's observable behavior, such as instructions that calculate values that are never used. It's an important step in optimizing the generated program.

Intermediate Code Generation is the creation of a platform-independent code representation from source code. This form allows for optimization and easier translation to the target machine code.
