WAIT! Have you read Getting Started, Beginner Mistakes, and some of the related OS theory?

Notes

• The rust libcore can easily be included in a kernel, it's analogous to C's freestanding headers
• Enable `--gc-sections` in ld to avoid having to define symbols you don't need (e.g. floating point math functions)
• Always use a target json file ("Flexible Target Specifications), and disable stack checking.
  • Stack checking requires using thread-local storage

Examples

• https://github.com/thepowersgang/rust-barebones-kernel - A framework written in rust 1.0 alpha, supporting x86 and x86-64, boots offf multiboot.
• https://github.com/charliesome/rustboot - VERY old (rust 0.7), includes a bootsector.
