exec.c: Use correct attrs in cpu_memory_rw_debug() 
In the softmmu version of cpu_memory_rw_debug(), we ask the
CPU for the attributes to use for the virtual memory access,
and we correctly use those to identify the address space
index. However, we were not passing them in to the
address_space_write_rom() and address_space_rw() functions.

The effect of this was that a memory access from the gdbstub
to a device which had behaviour that was sensitive to the
memory attributes (such as some ARMv8M NVIC registers) was
incorrectly always performed as if non-secure, rather than
using the right security state for the CPU's current state.

Build Status Build status

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
