## What it is
cargo-asm is a cargo subcommand that displays the assembly or LLVM IR generated for Rust source code. It supports querying functions and methods by path, annotating assembly with Rust source, and outputting Intel/AT&T syntax or a JSON AST.

## Use cases
- view the assembly generated for a Rust function
- inspect LLVM IR emitted by rustc for a method
- check how the compiler optimizes a hot function
- compare assembly across Rust nightly and stable
- dump assembly as JSON for further processing
- see Rust source interleaved with generated assembly

## When to choose
- you need to inspect compiler output for performance tuning of Rust code
- you want a quick cargo-integrated way to view asm or LLVM IR for specific functions
- you work across x86, ARM, MIPS, PowerPC, or SPARC targets

## When to avoid
- you need a general-purpose disassembler for binaries rather than compiler output
- you need a debugger or profiler instead of static code inspection
- you need actively developed tooling with frequent updates
