2022-12-18Rollup merge of #105842 - compiler-errors:arg-name-sugg, r=petrochenkovMatthias Krüger-7/+7
print argument name in arg mismatch if possible A bit more contextual than just `/* value */`, at least when the argument is named something related to its context. The UI test cases are... not super convincing, but also they're minimized tests.

Migrate rustc_mir_build diagnostics Rebases https://github.com/rust-lang/rust/pull/100854 ~~The remaining issue is how to better resolve https://github.com/rust-lang/rust/commit/72bea68af4ee2a41c44998916f6a789163f12e7d~~ ~~The diagnostic macros seems to generate a broken diagnostic, and I couldn't figure out how to manually format the fluent message, so I hardcoded the format string for now. I'd like pointers to a better fix for this.~~ Also, I'm not 100% sure I didn't mess up a rebase somewhere 🙂 r? `@davidtwco`

2022-12-17Auto merge of #105800 - lqd:dylib-thinlto, r=bjorn3bors-0/+52
Don't copy symbols from dylibs with `-Zdylib-lto` When `rustc_driver` started being built with `-Zdylib-lto -Clto=thin`, some libstd symbols were copied by the LTO process into the dylib. That causes duplicate local symbols that are not present otherwise. Depending on the situation (lib loading order apparently), the duplicated symbols could cause issues: `rustc_driver` overrode the panic hook, but it didn't apply to rustc main's hook (the default from libstd). This is the cause of #105637, in some situations the panic hook installed by `rustc_driver` isn't executed, and only libstd's backtrace is shown (and a double panic). The query stack, as well as the various notes to open a GH about the ICE, don't appear. It's not clear exactly what is needed to trigger the issue, but I have simulated a reproducer [here](https://github.com/lqd/issue-105637) with cargo involved, the incorrect panic hook is executed on my machine. It is hard to reproduce in a unit test: `cargo run` + `rustup` involves LD_LIBRARY_PATH, which is not the case for `compiletest`. cargo also adds unconditional flags that are then overridden in [`bootstrap` when building rustc with `rust.lto = thin`](https://github.com/rust-lang/rust/blob/9c07efe84f28a44f3044237696acc295aa407ee5/src/bootstrap/compile.rs#L702-L714) as done on CI). All this to say the compilation and execution environment in `bootstrap` leading to the bug building `rustc_driver` is different from our UI tests, and I believe one of the reasons it's hard to make an exact reproducer test. Thankfully there's _still_ a difference in the behavior though: although in the unit test the correct panic hook seems to be executed compared to my repro and the current nightly, only the fix removes the double panic here. The `7e8277aefa12f1469fb1df01418ff5846a7854a9` `try` build: - fixes the reproducer repo linked above - restores the ICE messages from https://github.com/rust-lang/rust/issues/105321 back to the state in its OP compared to the description in https://github.com/rust-lang/rust/issues/105637 - restores the ICE message and the query stack from https://github.com/rust-lang/rust/issues/105777 compared to nightly While I believe this technically fixes the P-critical issue https://github.com/rust-lang/rust/issues/105637, I would not want to close it yet as we may want to backport to beta/stable (if a point release happens, it would fix the ICEs reported on 1.66.0, which is built with ThinLTO on linux). Once this PR lands, I'll also open another PR to re-enable ThinLTO on x64 darwin's dist builder.

2022-12-16Auto merge of #102318 - Amanieu:default_alloc_error_handler, r=oli-obkbors-101/+34
Stabilize default_alloc_error_handler Tracking issue: #66741 This turns `feature(default_alloc_error_handler)` on by default, which causes the compiler to automatically generate a default OOM handler which panics if `#[alloc_error_handler]` is not provided. The FCP completed over 2 years ago but the stabilization was blocked due to an issue with unwinding. This was fixed by #88098 so stabilization can be unblocked. Closes #66741

2022-12-15Auto merge of #104616 - RalfJung:ctfe-alignment, r=oli-obk,RalfJungbors-220/+271
always check alignment during CTFE We originally disabled alignment checks because they got in the way -- there are some things we do with the interpreter during CTFE which does not correspond to actually running user-written code, but is purely administrative, and we didn't want alignment checks there, so we just disabled them entirely. But with `-Zextra-const-ub-checks` we anyway had to figure out how to disable those alignment checks while doing checks in regular code. So now it is easy to enable CTFE alignment checking by default. Let's see what the perf consequences of that are. r? `@oli-obk`
