# elfx86exts
Disassemble a binary and print out which instruction set extensions it uses.
Despite the utterly misleading name, this tool supports ELF and MachO binaries,
and perhaps other formats as well, and has preliminary support for ARM64 as well
as X86/64. It used to be a lot more limited!
I have no idea what I'm doing here, but it seems to work. There are several
Rust crates that make this pretty easy to do.
## Change Log
See [the CHANGELOG on the release
branch](https://github.com/pkgw/elfx86exts/blob/release/CHANGELOG.md) for news
about what has changed between releases.
## Installation
### Prepackaged
This tool is installable through a few package managers:
- [Arch Linux AUR](https://aur.archlinux.org/packages/elfx86exts/)
- [conda-forge](https://anaconda.org/conda-forge/elfx86exts) (Linux only right now)
If you are interested in packaging `elfx86exts` in a new packaging system, or
have already done so, please submit a PR to add it to this list.
### Compiling the Latest Release
If a package is not available, in most cases it will be straightforward to
build `elfx86exts` yourself. Dependencies are:
- A [Rust](https://www.rust-lang.org/) toolchain
- The [Capstone](http://www.capstone-engine.org/) disassembly engine
Both of these dependencies are available through a wide variety of package
managers. Once they’re set up, you don’t even need to check out this
repository to install the latest release. Simply run:
```
cargo install elfx86exts
```
… and the tool will be installed in your Cargo binary directory, usually
`~/.cargo/bin/`. When using this method, you need to add the `--force` flag to
upgrade from one version to the next.
### Compiling the Code From Git
This is hardly any more difficult than the above. Check out this repository,
then run:
```
cargo install --path .
```
To develop the program, use the `cargo build` and `cargo run` commands. For
more information, see
[The Cargo Book](https://doc.rust-lang.org/cargo/index.html).
