Summary
Compiler tuning reference for Rust developers who need to shrink binaries, speed up release builds, or read what the compiler is actually generating. Covers Cargo profile settings (LTO, codegen units, opt-level), RUSTFLAGS for target-specific optimization, and how to emit assembly or MIR for inspecting output. The monomorphization section is honest about generic code bloat and shows cargo-llvm-lines for measuring it. If you're debugging why your Rust binary is 50MB or wondering whether to use fat LTO versus thin, this gives you the flags and tradeoffs without making you read the rustc book cover to cover.
