CHERI LLVM Compiler with Morello Support

Morello is supported by LLVM open-source toolchains based on the CHERI Clang/LLVM toolchain from the University of Cambridge (UoC). Note: These are experimental toolchains and as such features may be missing.

Android CHERI LLVM/Clang toolchain	Includes a C/C++ compiler (clang), linker (lld), debugger (lldb), various utilities (such as assembler and disassembler) and run-time libraries.
Bare-metal toolchain for architecture exploration projects	Includes a C/C++ compiler (clang), linker (lld), a standard C library (newlib), a standard C++ library (libc++, libc++abi) and various utilities (such as assembler & disassembler). Arm Development Studio Morello Edition is also available as a development environment for the bare-metal configuration.
AArch64 Linux CHERI LLVM/Clang toolchain	This is an AArch64-hosted toolchain for Linux that can build purecap binaries for Morello target. It includes a C/C++ compiler (clang), linker (lld), various utilities and run-time libraries such as purecap versions of CRT objects and compiler-rt. It can be used together with any C library supporting Morello (for example, Morello port of Musl C library).

Morello Platform Model

The Morello Platform Model is a Fixed Virtual Platform (FVP) based on Arm Fast Models. The FVP is a functional model of the Morello platform and supports the same software stacks as the hardware.

Morello Instruction Emulator

The Morello Instruction Emulator (Morello IE) is an experimental tool for software developers and researchers who are interested in experimenting with the Morello architecture. The tool allows you to run userspace Morello applications on AArch64 Linux systems in a non-Morello environment. The tool also includes runtime instrumentation that can collect information about events and counters related to Morello. In addition, Morello IE includes an interactive debugger to help with running Morello applications.

Morello IE can be used for:

Experiments with Morello userspace applications on non-Morello AArch64 Linux systems.
Evaluate compartmentalization solutions and experiment with the Linux system call ABI.
Test, debug and trace existing software being ported to Morello.
Trace-based performance analysis and cache modelling for Morello applications.
