d4eb4d2c47 write generated code to disk for easier inspection 
now that the generated code is actually readable let's make it easier to access

this commit also documents how to inspect the generated code via
`rtfm-expansion.rs` and `cargo-expand`

485601245b rtfm::app: update error message 2019-05-01 20:49:25 +02:00
Jorge Aparicio
a452700628 implement RFCs 147 and 155, etc. 
This commit:

- Implements RFC 147: "all functions must be safe"

- Implements RFC 155: "explicit Context parameter"

- Implements the pending breaking change #141: reject assign syntax in `init`
  (which was used to initialize late resources)

- Refactors code generation to make it more readable -- there are no more random
  identifiers in the output -- and align it with the book description of RTFM
  internals.

- Makes the framework hard depend on `core::mem::MaybeUninit` and thus will
  require nightly until that API is stabilized.

- Fixes a ceiling analysis bug where the priority of the system timer was not
  considered in the analysis.

- Shrinks the size of all the internal queues by turning `AtomicUsize` indices
  into `AtomicU8`s.

- Removes the integration with `owned_singleton`.

77def32454 Merge #170 
170: check task priority at compile time r=TeXitoi a=japaric

before we were checking the priority at runtime. The compile time error message
when the priority is too high is kind of awful though.

73529ea650 reject duplicate arguments in #[interrupt] and #[exception] 
This program was being accepted:

``` rust
 #[task(
    capacity = 1,
    capacity = 2,
    priority = 1,
    priority = 2,
)]
fn foo() {}
```

now it will trigger a compiler error

this doesn't change functionality per se but improves diagnostics in some cases. Some hard errors
have becomes warnings, for example: when `resources` is empty, or when `idle.path` is set to the
default `idle` path.

0b5afce771 refactor Resource / Threshold into its own crate, drop task!, tweak rtfm::atomic 
task! can be re-added in a backward compatible fashion and I'd like to not have
two ways to assign a task handler to an interrupt / exception in the first
release.

rtfm::atomic now uses the `Threshold` token instead of the `CriticalSection`
token. This reduces overhead by dropping the "are interrupts enabled?" check.

3cebf49a2f syntax tweaks, relax check, add set_pending(), deal with imported types 
- allow trailing commas in list of resources

- make task.resources optional

- add rtfm::set_pending function which can be used to force an interrupt into
  the pending state. This is a replacement of the old rtfm::request.
  rtfm::set_pending takes the Interrupt enum provided by the device crate as
  argument. (The old rtfm::request took a task function as argument)

- the user may want to use types they imported into the root of the crate. These
  types are not available in e.g. `mod idle` so `idle::Resources` *can't* be
  defined in that module. To workaround this problem `idle::Resources` will be
  defined in the root, with some other name, and then be re-exported in the
  `idle` module.

- remove the "a resource only used by one task should be local data" check. In
  some cases you do want a resource owned by a single task instead of local
  data since `init` can access resources but not a task local data.
