## Historique du projet et usages

elfx86exts is a Rust command-line tool that disassembles binaries and reports which instruction-set extensions they use.

### Historique du projet

The project began as an x86 ELF-oriented analyzer, but the official README now notes that the name is misleading because the tool supports ELF and Mach-O binaries and has preliminary ARM64 support as well as x86 and x86-64.

The release branch ChangeLog records the first release in 2017, Mach-O and PE support in 2018, minimum Intel CPU generation reporting in 2018, Cranko-based release workflow changes in 2020, Capstone and object crate updates in 2021, and ARM64 support in 2023.

### Historique d'adoption

The official README says the tool is installable through package managers including Arch Linux AUR and conda-forge, and the supplied metadata records Homebrew, Debian, Nix, Pacman, and Ubuntu package names. The Cargo metadata documents `cargo install elfx86exts` as the direct Rust package-manager path.

### Modes d'utilisation

The package-nerd workflow is to install the binary, point it at a compiled executable or library, and use its reported ISA-extension set to understand portability constraints, CPU-generation requirements, or unexpected compiler output.

### Pourquoi les passionnés de paquets s'y intéressent

elfx86exts sits at the intersection of binary analysis and packaging: maintainers care about which CPU features a built artifact actually requires, especially when distributing binaries across older x86 machines, Linux distributions, macOS systems, or heterogeneous build farms.

### Chronologie

- 2017-09-29: Initial release.
- 2018-01-23: Version 0.2.0 added Mach-O and PE support.
- 2018-10-16: Version 0.3.0 added minimum Intel CPU generation reporting.
- 2021-10-18: Version 0.5.0 updated disassembly to Capstone 0.10 and object 0.27.
- 2023-10-12: Version 0.6.0 added preliminary ARM64 support.
- 2023-10-22: Version 0.6.2 fixed excessive memory consumption.

### Related projects

- Related projects and libraries include Capstone, the Rust object crate, compiler toolchains, binary packaging systems, and CPU feature inspection tools.
