This repository is a 'super project' that is based on gitslave and contains 'attached' git repositories and a build system for LLVM that targets ARM and AVR mcu/cores bare metal development.

Currently targeting arm-none-eabi and building on OS-X:

• llvm
• clang
• clang-tools-extra
• compiler-rt
• polly
• test-suite
• lld
• gcc (arm-none-eabi-g*)
• binutils (arm-none-eabi-*)
• gdb (arm-none-eabi-gdb)
• qemu (qemu-system-arm)
• ninja
• opendocd
• ARM CMSIS
• newlib 2.0

This is a bleeding-edge toolchain and is not for the weak of heart.

Along for native host LLVM builds, the build process also supports Canadian Cross :

• OS-X (x86_64)
• Linux (x86_64, ARM)
• Windows (x86_64)

TODO:

• Document install steps
• Document build system
• Intergration testing (via QEMU guests)
