I'd like to enable caches for dependency-less functions like this one but I'm not sure a debug assertion is enough. Can we instead of make sure at compile time that a function cannot have dependencies? One way to do that would be to not give it access to the tcx in the first place. From the looks of it, erasing types (and probably quite a few other things like it) only needs access to interners. Maybe we could split out a subset of the context that can do nothing expect for allocating stuff. That would be a safe and generic extension of the query system that might help performance in quite a few places. I'd prefer that to one-off solutions with manual checking.

Zoxc · 2019-04-01T22:11:56Z

Can we instead of make sure at compile time that a function cannot have dependencies?

I don't see how, given that we allow access to TyCtxt in TLS. The debug-only dependency fixed in this PR doesn't have a tcx for example.

michaelwoerister · 2019-04-02T09:01:49Z

I don't see how, given that we allow access to TyCtxt in TLS. The debug-only dependency fixed in this PR doesn't have a tcx for example.

Yeah, that's true :(

It would still be good to turn this into a generic, sanctioned pattern with safe-guards against foot gunning ourselves. Maybe:

Allow a way of defining a dependency-less query where the provider only gets access to a restricted version of the tcx (e.g. just interners). That already gives a good indication that one should not use the tcx.
Keep the debug-only runtime check from this PR in place for such queries.
Add documentation to the rustc-guide of what these queries are and why they work the way they work.

The tcx would still be accessible through TLS at least we'd have documentation and a clear template that people can use without having to remember that they need to do their checking and what they are allowed to do and what not.

cc @nikomatsakis, who (I think) mentioned wanting to support dependenciless functions in Salsa too.

Zoxc · 2019-04-14T13:52:42Z

This is also the only thing using anon queries, which I'd also like to remove since it doesn't make sense to me.

michaelwoerister · 2019-04-24T11:48:52Z

As I said, I'm not against doing something like this in principle. But this isn't a pressing issue (i.e. the current solution works and performance improvement nice but not stellar), so I'd prefer if we supported this pattern in a general way (along the lines I described above) instead of doing a one-off solution.
