+//! This test runs a basic application for thumb targets, using the cortex-m crate.
+//!
+//! These targets are very bare-metal: the first instruction the core runs on
+//! power-on is already user code. The cortex-m-rt has to initialize the stack, .data,
+//! .bss, enable the FPU if present, etc.
+//!
+//! This test builds and runs the applications for various thumb targets using qemu.
+//!
+//! How to run this
+//! $ ./x.py clean
+//! $ ./x.py test --target thumbv6m-none-eabi,thumbv7m-none-eabi tests/run-make
+//!
+//! For supported targets, see `example/.cargo/config.toml`
+//!
+//! FIXME: https://github.com/rust-lang/rust/issues/128733 this test uses external
+//! dependencies, and needs an active internet connection
