Generator Resume Arguments #68524

jonas-schievink · 2020-01-24T21:43:13Z

cc #43122 and #56974

Blockers:

Fix miscompilation when resume argument is live across a yield point (#68524 (comment))
Fix 10% compile time regression in await-call-tree benchmarks (#68524 (comment))
- Fix remaining 1-3% regression (#68524 (comment)) - resolved (#68524 (comment))
Make dropck rules account for resume arguments (#68524 (comment))

Follow-up work:

Change async/await desugaring to make use of this feature
Rewrite box_region.rs to use resume arguments (this shows up in profiles too)

src/librustc_mir/dataflow/move_paths/builder.rs

-            TerminatorKind::Yield { ref value, .. } => {
+            TerminatorKind::Yield { ref value, resume_arg: ref place, .. } => {
+                self.create_move_path(place);
+                self.gather_init(place.as_ref(), InitKind::Deep);


I noticed that the order of gather_init and gather_operand is swapped compared to DropAndReplace, but I'm not sure if it matters.

Zoxc · 2020-01-25T16:03:13Z

I think I'd prefer to make this PR make the argument be a type parameter instead of a associated type before landing to avoid some unnecessary churn in the compiler and for users of generators.

I also don't know how correct this is with regards to drops and references, but those concerns could be delayed by just adding a 'static + Copy bound to the generator argument in typeck. That would be good enough for async/await.

bjorn3 · 2020-01-25T16:18:45Z

I think an assocated type makes more sense, as it is very unlikely to ever be overloaded for different resume types.

matthewjasper · 2020-01-25T16:22:35Z

Async generators (should) implement for<'a, 'b> Geneator<&'a Context<'b>, Yield = ()>, which needs a type parameter.
