- Currently unimplemented:
- - event parameters
- - memory protocol semantics
- - 'queuing' internal event semantics
- - concurrency semantics
- Roadmap
- -------
- (DONE) Milestone 1: Initial compilation to Rust
-
- - (DONE) entering and exiting states correctly
- - (DONE) incoming event triggers the right transition
- - (DONE) a port of the Controller class to Rust
- - (DONE) one implemented action: raise output event
- - (DONE) fixed semantics (YAKINDU-like)
- - "Take One" big step maximality
- - parent-first
- - (DONE) goal: subset of SCCD tests passes:
- semantics/big_step_maximality/test_flat_takeone.xml
- semantics/big_step_maximality/test_ortho_takeone.xml
- semantics/priority/test_source_parent.xml
- semantics/priority/test_explicit_flat.xml
- semantics/priority/test_explicit_ortho.xml
- - no history
- - no action language
- - guards evals and action stmts are just logged to console
- - guards always true, actions no effect
- - no event parameters
- (DONE) Milestone 2: Minimal support for semantic variability:
- - (DONE) Priority: Child-first
- - (DONE) Big-Step Maximality: Take Many
- - (DONE) goal: following tests should pass:
- semantics/priority/test_source_child.xml
- semantics/big_step_maximality/test_flat_takemany.xml
- semantics/big_step_maximality/test_ortho_takemany.xml
- (DONE) Milestone 3: Support history
- (DONE) Milestone 4: Timers (should be easy)
- (DONE) Milestone 5: Internal Events
- (DONE) Milestone 6: Action language
- Insights
- --------
- - Rust compiler warnings are actually useful for the modeler:
- - e.g. An unexecutable transition is detected as an unreachable statement
- - e.g. An unused event is detected as an unused variable or never-constructed enum variant.
- Performance over time
- ---------------------
- for test semantics/big_step_maximality/test_ortho_takemany.xml
- commit 354576dd47587fd8e6277539a26a4743b2167565 - Dec 17, 2020 - action lang working
- binary size, no opt: 513760 bytes
- binary size, opt-level=3: 421056 bytes
- binary size, opt-level=3 inline-threshold=1000: 421056 bytes
- binary size, opt-level=z: 429200 bytes
- instruction count (perf stat) (opt-level=3): 575.539 instructions:u
- commit aa6a734f7d900479de9be99a8cdf68af0d561481 - Dec 2, 2020 - implemented big-step maximality
- binary size, no opt: 478976 bytes
- binary size, opt-level=3 inline-threshold=1000: 410880 bytes
- binary size, opt-level=z: 413576 bytes
- instruction count (perf stat) (opt-level=3): 580.701 instructions:u
- Performance insights
- - instruction count improved a little over time (but could be due to non-relevant changes such as debug output)
- - binary size slightly worse when optimizing for size (opt-level=z). this means that inlining is actually reducing the binaries' size, as we would expect (lots of dead code can be eliminated)
