How does a developer prevent an attacker from taking control of a program when the developer is providing the tools to the attacker? What are code reuse attacks and how can the Arm Architecture remove the vulnerabilities? How can someone use these architectural…
gcc-arm-none-eabi-8: GDB segmentation fault
I'm seeing a segmentation fault in gcc-arm-none-eabi-8-2018-q4-major when I try to debug a binary written in Rust (it's actually the TockOS kernel).
Rust is actually using LLVM nightly to generate the binary. I wonder if that's causing issues…

Aarch64 llvm unrecognized instruction mnemonic
I am trying to use ARM inline assembly in a C code. I am compiling using aarch64-linux-android-clang version 3.8.243773, the 64 bit llvm toolchain from Android NDK R11.
The inline assembly code is as follows:
