Fix misc printing issues in `emit=stable_mir` #118364

ouz-a · 2023-11-27T10:40:38Z

Previously our } closed early and looked bit weird, now it closes when function call ends, and previously Adt printing was too verbose now it's similar to mir output

I've asked before but I will ask again -- is it possible for you to prioritize working on some sort of test?

It's kinda sketchy to be putting up PRs like this with absolutely no evidence that it's doing anything.

Alright will start working on a test immediately

Opened PR for the test #118375

…=compiler-errors Add -Zunpretty=stable-mir output test As strongly suggested here rust-lang#118364 (comment) this adds output test for `-Zunpretty=stable-mir`, added test shows almost all the functionality of the current printer. r? `@compiler-errors`

compiler-errors · 2023-11-27T17:46:56Z

Do you mind rebasing this on top of #118375? Then you can bless the tests in your commit and see the output changes due to these tweaks.

Just rebased and run bless

I think this is a good opportunity to make more tweaks to the output since I can now see what's broken 😃 thanks for that

Also, plz squash the "rebase" commit into the "fix" commit.

No problem, it's better for someone other than me to also look at this and have some opinion about it 😄

I noticed that the successor for Goto terminators is missing the bb in the label. For example, we're printing something like:

goto -> 5

when I expected:

goto -> bb5

This is looking so much better. I'm hoping we can merge this after the next revision. Btw, have you compared the expected file with the internal MIR dump? It might be helpful to spot what's missing or what's wrong.

celinval · 2023-12-17T21:22:33Z

tests/ui/stable-mir-print/basic_function.stdout

-        _2 = 1 Add const 1_i32
-        assert(!move _2 bool),"attempt to compute `{} + {}`, which would overflow", 1, const 1_i32) -> [success: bb1, unwind continue]
+        _2 = CheckedAdd(_1, const 1_i32)
+        assert(!move _2 bool),"attempt to compute `{} + {}`, which would overflow", _1, const 1_i32) -> [success: bb1, unwind continue]


Where's this bool coming from?

celinval · 2023-12-17T21:28:17Z

tests/ui/stable-mir-print/basic_function.stdout

    bb0: {
-        _3 = refShared1
+        _3 = &1


Should this be _1?

celinval · 2023-12-17T21:29:03Z

tests/ui/stable-mir-print/basic_function.stdout

-        _5 = refMut {
-    kind: TwoPhaseBorrow,
-}2
+        _5 = &mut 2


Where's _5 declaration?

celinval · 2023-12-17T21:30:43Z

tests/ui/stable-mir-print/basic_function.stdout

 }
+fn bar(_0: &mut std::vec::Vec) -> std::vec::Vec {
+    let mut _0: std::vec::Vec;
+    let mut _1: &std::vec::Vec;


Are we missing _1 initialization?

Will go trough another pass and then compare with mir output

I been meaning to look at this for some time but I been extremely busy with life/job in past couple months 😓

celinval · 2024-03-16T23:56:03Z

Hey @ouz-a do you mind if I take a stab at this?

Yeah, go ahead.

…rrors Fix misc printing issues in emit=stable_mir Trying to continue the work that `@ouz-a` started here: rust-lang#118364 Few modifications beyond fixes: 1. I made the `pretty_*` functions private. 2. I added a function to print the instance body 3. Changed a bunch of signatures to write to the writer directly. 4. Added a function to translate the place to its internal representation, so we could use the internal debug implementation. 5. Also removed `pretty_ty`, replaced by Display implementation of Ty which uses the internal display.
