-/// Attribute to declare the entry point of the program
-///
-/// **IMPORTANT**: This attribute must appear exactly *once* in the dependency graph. Also, if you
-/// are using Rust 1.30 the attribute must be used on a reachable item (i.e. there must be no
-/// private modules between the item and the root of the crate); if the item is in the root of the
-/// crate you'll be fine. This reachability restriction doesn't apply to Rust 1.31 and newer releases.
-///
-/// The specified function will be called by the reset handler *after* RAM has been initialized. In
-/// the case of the `thumbv7em-none-eabihf` target the FPU will also be enabled before the function
-/// is called.
-///
-/// The type of the specified function must be `[unsafe] fn() -> !` (never ending function)
-///
-/// # Properties
-///
-/// The entry point will be called by the reset handler. The program can't reference to the entry
-/// point, much less invoke it.
-///
-/// `static mut` variables declared within the entry point are safe to access. The compiler can't
-/// prove this is safe so the attribute will help by making a transformation to the source code: for
-/// this reason a variable like `static mut FOO: u32` will become `let FOO: &'static mut u32;`. Note
-/// that `&'static mut` references have move semantics.
-///
-/// # Examples
-///
-/// - Simple entry point
-///
-/// ``` no_run
-/// # #![no_main]
-/// # use cortex_m_rt_macros::entry;
-/// #[entry]
-/// fn main() -> ! {
-///     loop {
-///         /* .. */
-///     }
-/// }
-/// ```
-///
-/// - `static mut` variables local to the entry point are safe to modify.
-///
-/// ``` no_run
-/// # #![no_main]
-/// # use cortex_m_rt_macros::entry;
-/// #[entry]

-///
-/// (b) Only available on ARMv8-M
-///
-/// # Usage
-///
-/// `#[exception] fn HardFault(..` sets the hard fault handler. The handler must have signature
-/// `[unsafe] fn(&ExceptionFrame) -> !`. This handler is not allowed to return as that can cause
-/// undefined behavior.
-///
-/// `#[exception] fn DefaultHandler(..` sets the *default* handler. All exceptions which have not
-/// been assigned a handler will be serviced by this handler. This handler must have signature
-/// `[unsafe] fn(irqn: i16) [-> !]`. `irqn` is the IRQ number (See CMSIS); `irqn` will be a negative
-/// number when the handler is servicing a core exception; `irqn` will be a positive number when the
-/// handler is servicing a device specific exception (interrupt).
-///
-/// `#[exception] fn Name(..` overrides the default handler for the exception with the given `Name`.
-/// These handlers must have signature `[unsafe] fn() [-> !]`. When overriding these other exception
-/// it's possible to add state to them by declaring `static mut` variables at the beginning of the
-/// body of the function. These variables will be safe to access from the function body.
-///
-/// # Properties
-///
-/// Exception handlers can only be called by the hardware. Other parts of the program can't refer to
-/// the exception handlers, much less invoke them as if they were functions.
-///
-/// `static mut` variables declared within an exception handler are safe to access and can be used
-/// to preserve state across invocations of the handler. The compiler can't prove this is safe so
-/// the attribute will help by making a transformation to the source code: for this reason a
-/// variable like `static mut FOO: u32` will become `let FOO: &mut u32;`.
