Merge #390
390: Spawn and schedule from anywhere r=AfoHT a=korken89 This PR moves RTIC to the spawn and schedule from anywhere syntax. Notable changes: * We do no longer support non-`Send` types. * Some extra code is generated as any task may spawn/schedule any task. However Rust/LLVM does a great job optimizing away non used instantiations (no real code-size difference observed). * Worst case priority inversion has increased, but it is now predictable. Upsides: * With this we should be able to support async/await. * RTIC tasks can now be callbacks (spawned and scheduled). * RTIC tasks can be stored. Needs the following PR to land first: https://github.com/rtic-rs/rtic-syntax/pull/34 The following now works: ```rust #[rtic::app(device = lm3s6965, monotonic = rtic::cyccnt::CYCCNT)] mod app { #[init] fn init(mut cx: init::Context) -> init::LateResources { // Init stuff... // New spawn syntax foo::spawn().unwrap(); // New schedule syntax bar::schedule(now + 4_000_000.cycles()).unwrap(); init::LateResources {} } #[task] fn foo(_: foo::Context) {} #[task] fn bar(_: bar::Context) {} extern "C" { fn SSI0(); } } ``` Co-authored-by: Per Lindgren <per.lindgren@ltu.se> Co-authored-by: Emil Fresk <emil.fresk@gmail.com>
