@ -13,7 +13,7 @@ Unicorn is a lightweight, multi-platform, multi-architecture CPU emulator framew
Unicorn offers some unparalleled features:
- Multi-architecture: ARM, ARM64 (ARMv8), M68K, MIPS, PowerPC, RISCV, SPARC, and X86 (16, 32, 64-bit)
- Multi-architecture: ARM, ARM64 (ARMv8), M68K, MIPS, PowerPC, RISCV, SPARC, S390X 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, Android, *BSD & Solaris confirmed)

@ -0,0 +1,13 @@
current status:
- only build s390x arch (see CMakeLists.txt)
- sample_s390x crash, due to qemu/target/s390x/cpu.c :: cpu_s390_init() still has bugs
Todo:
- fix qemu/target/s390x/cpu.c, so sample_s390x works
- enable building all arch to fix conflicts
- support more registers in qemu/target/s390x/unicorn.c
- storage-keys needed?
- find & fix potential memory leaking with valgrind
- sync with "dev" branch of github unicorn
