Clang

When you need to squeeze more out of Clang than just dropping in GCC flags, this walks you through the LLVM-specific tooling that actually matters: optimization remarks that show you why loops didn't vectorize, clang-tidy for real static analysis, ThinLTO for sane link times on big codebases, and those superior diagnostics with fix-it hints. Covers the PGO workflow with llvm-profdata, flags like -Oz and -Rpass-missed, and the macOS/FreeBSD quirks where Clang is the system compiler. Honest take: if you're still just using -O2 -Wall, you're leaving a lot on the table.
