rust/tests/run-make/thumb-none-cortex-m/rmake.rs

//! Test building of the `cortex-m` crate, a foundational crate in the embedded ecosystem
//! for a collection of thumb targets. This is a smoke test that verifies that both cargo
//! and rustc work in this case.
//!
//! How to run this
//! $ ./x.py clean
//! $ ./x.py test --target thumbv6m-none-eabi,thumbv7m-none-eabi tests/run-make
//!
//! Supported targets:
//! - thumbv6m-none-eabi (Bare Cortex-M0, M0+, M1)
//! - thumbv7em-none-eabi (Bare Cortex-M4, M7)
//! - thumbv7em-none-eabihf (Bare Cortex-M4F, M7F, FPU, hardfloat)
//! - thumbv7m-none-eabi (Bare Cortex-M3)
