Create compilation target versions of `::alloc::Layout` by Dante-Broggi · Pull Request #64299 · rust-lang/rust

Dante-Broggi · 2019-09-09T00:49:00Z

This PR adds 2 types LayoutPositionPref and MemoryPosition which are like ::alloc::Layout but use layout::Size and layout::{AbiAndPrefAlign, Align}, and replaces most pairs of Size and *Align with one of them.

Most of the commits are semi-minimal changes after changing a single (group of) APIs, which is why there are so many of them. If desired they could be squashed.

Edit: also, each commit (in order) satisfies at least “./x.py check -i”.

Overall, other than API breakage, this is almost a pure refactoring, the only difference should be that I changed many places to be more correct for non-stride (.size != .size.aligned_to(.align)) sizes, which IIRC Rust currently does not allow anyway.

So I did a first shallow review, the general idea looks good to me.

Wrt the test failures, I think the best way to figure out what causes them is to bisect your own PR. So take the middle commit, see if that passes tests, if it does, take the commit between the currently working commit and the last commit. Repeat until failure.

Once you know which commit causes the failure, it will be much simpler to figure out the problem.

Dante-Broggi · 2019-09-20T23:50:15Z

Commenting this for the record: git bisect shows the first bad commit is LayoutDetails.pref_pos
However, the failure was different on my mac (laptop) than on the Linux CI. Specifically, 99% (~50/9009) of the (ui?) tests all fail with:

thread 'rustc' panicked at 'assertion failed: `(left == right)`
left: `8`,
right: `0`', /Users/dantebroggi/.cargo/registry/src/github.com-1ecc6299db9ec823/hashbrown-0.5.0/src/raw/mod.rs:1086:9

I, still, have no idea what's causing this, the failure in CI, or why they are different.

I spotted two cases of different behaviour, which may explain the problem.

Dante-Broggi · 2019-09-22T00:36:06Z

So those changes weren't the cause of the local failures, but I did a rebase and finished up changing Allocation, so I am going to push the changes again.

oli-obk · 2019-09-22T10:40:58Z

Huh... you can test master without failures though, right?

Dante-Broggi · 2019-09-22T18:10:29Z

On master the only failure is "---- [codegen] codegen/issue-44056-macos-tls-align.rs stdout ----"

Dante-Broggi · 2019-09-28T03:09:41Z

So, I haven't found out what's causing the local failures, but I did do a full re-clone of this PR branch into a new directory, and in the new clone the only failures are "[debuginfo-gdb+lldb] debuginfo/*" tests.

Therefore the "ui/*" local failures (which still occur in the original clone) are all due to peculiarities in my clone.

Hi @Dante-Broggi I am unsure how to proceed here. Even if we do this refactoring we are no step closer to the swift repr or to separating stride from size, because it would break all unsafe code relying on the current scheme.

Without first resolving the language/stability I do not believe we can merge this PR or any other moving in this direction

Ping from triage:
@oli-obk Do you think this PR should be marked as blocked?
cc: @Dante-Broggi @bjorn3
Thanks.

Dylan-DPC-zz · 2019-11-24T08:43:14Z

Marking this as blocked.

Dylan-DPC-zz · 2020-03-24T01:19:00Z

Given the fact this is blocked from long time and based on the comment #64299, it will take a while and the conflicts have accumulated enough to make this a mess when ready. Hence closing this and we can restart it later when ready if possible as it would be easier than rebasing this. Thanks for contributing :)
