Unicorn is a lightweight, multi-platform, multi-architecture CPU emulator framework
based on [QEMU](https://qemu.org).
def join_all(src, files):
return tuple(os.path.join(src, f) for f in files)
Unicorn offers some unparalleled features:
- Multi-architecture: ARM, ARM64 (ARMv8), M68K, MIPS, SPARC, and X86 (16, 32, 64-bit)
- Clean/simple/lightweight/intuitive architecture-neutral API
- Implemented in pure C language, with bindings for Crystal, Clojure, Visual Basic, Perl, Rust, Ruby, Python, Java, .NET, Go, Delphi/Free Pascal, Haskell, Pharo, and Lua.
- Native support for Windows & *nix (with Mac OSX, Linux, *BSD & Solaris confirmed)
- High performance via Just-In-Time compilation
- Support for fine-grained instrumentation at various levels
- Thread-safety by design
- Distributed under free software license GPLv2

; Why do we need this wrapper?
; Short answer: Windows default implementation of setjmp/longjmp is incompatible with generated code.
; A longer answer: https://blog.lazym.io/2020/09/21/Unicorn-Devblog-setjmp-longjmp-on-Windows/.
; From qemu os-win32 comments:
; > On w64, setjmp is implemented by _setjmp which needs a second parameter.
; > If this parameter is NULL, longjump does no stack unwinding.
; > That is what we need for QEMU. Passing the value of register rsp (default)
; > lets longjmp try a stack unwinding which will crash with generated code.
; It's true indeed, but MSVC doesn't has a setjmp signature which receives two arguements.
; Therefore, we add a wrapper to keep the second argument zero.
