+//! 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)
