rust Add `ConstKind::Expr`

Add `ConstKind::Expr`

Open JulianKnodt opened this issue 1 year ago • 57 comments

Starting to implement ty::ConstKind::Abstract, most of the match cases are stubbed out, some I was unsure what to add, others I didn't want to add until a more complete implementation was ready.

This will probably require a perf run, considering the size of consts increased, and if there's any alternative way to store consts more efficiently that would also be useful.

If you disagree with this performance assessment, please file an issue in rust-lang/rustc-perf.

Benchmarking this pull request likely means that it is perf-sensitive, so we're automatically marking it as not fit for rolling up. While you can manually mark this PR as fit for rollup, we strongly recommend not doing so since this PR may lead to changes in compiler perf.

Since the size of the const is the same, I wonder if the perf changes are caused by an increased number of branches, causing it to switch from a jump table to an explicit search?

@RalfJung I'll address your comments now! I just needed to get a working version first.

Aug 21 '22 19:08 JulianKnodt

Let's also see what @lcnr thinks about my feedback, in particular for naming he'll have a much better idea how to make things coherent. :)

Aug 21 '22 19:08 RalfJung

I thought we weren't going to switch to eager expansion in this PR since it seemed somewhat difficult to do

Aug 27 '22 10:08 BoxyUwU

@BoxyUwU that was my initial plan, but I ended up just lumping it in as per @lcnr's suggestion
