Do not hash allocations to name them. by cjgillot · Pull Request #119458 · rust-lang/rust

cjgillot · 2023-12-31T00:37:13Z

Computing the stable hash behind an Allocation can be quite slow. The given name does not provide a lot of benefit: a hash is not meaningfully easier to understand than an arbitrary index.

yeah, i agree that we should just let llvm deal with the unnamed consts lol

You are also removing the alloc_ prefix in this PR.

compiler-errors · 2024-01-01T17:32:43Z

@bjorn3: isn't that just because this is using the anonymous numbering from llvm? is there a reason to keep alloc_ as a prefix?

bjorn3 · 2024-01-01T17:46:10Z

It shows up in the symbol table, right? Seeing just a symbol named 1234 would be less understandable what it is. Especially when decompiling where it could show up as &1234 when taking a reference to alloc 1234 while looking as taking a reference to a literal integer 1234. Also there are probably tools that can't handle with identifiers that are not valid C identifiers. That these symbols are not public is a mitigating factor though.

cjgillot · 2024-01-07T20:38:10Z

@bjorn3 :

It shows up in the symbol table, right?

No, it does not. Those constants are "private unnamed_addr" for LLVM, and get no symbol in the binary. The only change is the name that appear in LLVM IR dumps.

I added hashing of them to make diffing LLVM IR easier.

⬆️ That still seems like a valid argument?

RalfJung · 2024-03-04T18:27:38Z

This PR is somehow back in the bors queue. It's not currently approved though. I don't know what's going on but I don't want bors to merge random PRs.^^

Since this is not the only affected PR...
~~@/bors treeclosed=100~~

EDIT(jieyouxu): bors pls don't see this

compiler-errors · 2024-03-04T18:29:51Z

@bors r-

Someone probably ran a resync?

RalfJung · 2024-03-04T18:30:24Z

Yeah but that shouldn't screw everything up.^^

compiler-errors · 2024-03-04T18:31:56Z

Right, I'm just pointing out that this is typically how PRs get back into the queue. I don't think anyone is gonna fix homu to stop doing that, though.

RalfJung · 2024-03-04T18:47:46Z

Okay it seems it's just "PRs that were approved and then failed CI" that got re-queued. Not catastrophic then, they'll probably fail again.
