Intern place projection by spastorino · Pull Request #65315 · rust-lang/rust

spastorino · 2019-10-11T18:18:19Z

This should sit on top of #65197. After that one merged, I'm gonna rebase on top of it.

The important commits are the last three and there's a bunch of code repetition that I'm going to remove but for that I need to refactor some things that probably need to be added before this PR.

Anyway this work helps as is because we can run perf tests :).

🔒 Merge conflict

This pull request and the master branch diverged in a way that cannot be automatically merged. Please rebase on top of the latest master branch, and let the reviewer approve again.

How do I rebase?

Assuming self is your fork and upstream is this repository, you can resolve the conflict following these steps:

git checkout intern-place-projection(switch to your branch)
git fetch upstream master(retrieve the latest master)
git rebase upstream/master -p(rebase on top of it)
Follow the on-screen instruction to resolve conflicts (check git status if you got lost).
git push self intern-place-projection --force-with-lease(update this PR)

You may also read Git Rebasing to Resolve Conflicts by Drew Blessing for a short tutorial.

Please avoid the "Resolve conflicts" button on GitHub. It uses git merge instead of git rebase which makes the PR commit history more difficult to read.

Sometimes step 4 will complete without asking for resolution. This is usually due to difference between how Cargo.lock conflict is handled during merge and rebase. This is normal, and you should still perform step 5 to update this PR.

are there no nice wrappers out there for (de)serializign a List?

I've fixed the deserialization and made it look a bit better. But what we have is very similar to what's done with ty https://github.com/rust-lang/rust/blob/e0fe4846e5ab3f5d8810280bbe0d217cafd491c9/src/librustc/ty/codec.rs#L247

r=me with one more as_local call

This prepares the code base for when projection is interned. Place's projection field is going to be `&List<PlaceElem<'tcx>>` so we won't be able to pattern match against it.

This is so we avoid a massive break of other people's code. Gonna run rustfmt and split the file on a different PR.

… r=oli-obk Intern place projection This should sit on top of rust-lang#65197. After that one merged, I'm gonna rebase on top of it. The important commits are the last three and there's a bunch of code repetition that I'm going to remove but for that I need to refactor some things that probably need to be added before this PR. Anyway this work helps as is because we can run perf tests :). r? @oli-obk /cc @nikomatsakis
