/*
 * Pattern-Driven Benchmark for Code Optimization
 * Main driver: runs all 7 categories, 28 patterns
 * Compile: gcc -O0 -o bench_O0 main.c -lm // no compiler optimization on GCC
 *          gcc -O2 -o bench_O2 main.c -lm // standard level optimization on GCC (inlining, loop unrolling, constant prop, DCE)
 *          gcc -O3 -o bench_O3 main.c -lm // max compiler optimization including (vectorization, function cloning, loop transformation + O2 stuff)
 * This measures the baseline: how much does the compiler
 * optimize the SLOW versions? Then compare with LLM output.
