AArch32 translation code does not distinguish between DISAS_UPDATE and DISAS_JUMP. Thus, we cannot use any of them without first updating PC in CPU state. Furthermore, it is too complicated to update PC in CPU state before PC gets updated in disas context. So it is hardly possible to correctly end TB early if is is not likely to be executed before calling disas_*_insn(), e.g. just after calling breakpoint check helper. Modify DISAS_UPDATE and DISAS_JUMP usage in AArch32 translation and apply to them the same semantic as AArch64 translation does: - DISAS_UPDATE: update PC in CPU state when finishing translation - DISAS_JUMP: preserve current PC value in CPU state when finishing translation This patch fixes a bug in AArch32 breakpoint handling: when check_breakpoints helper does not generate an exception, ending the TB early with DISAS_UPDATE couldn't update PC in CPU state and execution hangs. Backports commit 577bf808958d06497928c639efaa473bf8c5e099 from qemu |

Unicorn Engine
Unicorn is a lightweight, multi-platform, multi-architecture CPU emulator framework based on QEMU.
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 and Haskell.
- 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
