2023-12-04Dispose llvm::TargetMachines prior to llvm::Context being disposedWesley Wiser-6/+18
If the TargetMachine is disposed after the Context is disposed, it can lead to use after frees in some cases. I've observed this happening occasionally on code compiled for aarch64-pc-windows-msvc using `-Zstack-protector=strong` but other users have reported AVs from host aarch64-pc-windows-msvc compilers as well.
2023-11-13Auto merge of #117843 - Mark-Simulacrum:stable-next, r=Mark-Simulacrum 1.74.0bors-55/+314
[stable] Prepare 1.74.0 release https://forge.rust-lang.org/release/process.html#promote-branches-t-3-days-monday Also backports: * Disabling specialization as an alternative backport of "Fix excessive initialization and reads beyond EOF in io::copy(_, Vec<u8>) specialization #117576" * coverage: Avoid creating malformed macro name spans #117827 r? `@Mark-Simulacrum`
2023-11-12coverage: Regression test for #117788Zalathar-0/+74
Without the workaround applied, this test will produce malformed mappings that cause `llvm-cov` to fail. (And if it does emit well-formed mappings, they should be obviously incorrect.)
2023-11-12coverage: Avoid creating malformed macro name spansZalathar-0/+6
This method is trying to detect macro invocations, so that it can split a span into two parts just after the `!` of the invocation. Under some circumstances (probably involving nested macros), it gets confused and produces a span that is larger than the original span, and possibly extends outside its enclosing function and even into an adjacent file. In extreme cases, that can result in malformed coverage mappings that cause `llvm-cov` to fail. For now, we at least want to detect these egregious cases and avoid them, so that coverage reports can still be produced.
2023-11-12[beta] remove specialization that caused perf regressionThe 8472-54/+0
the fix on nightly is recent and should get time to bake, removal of the optimization is the less risky approach for a backport

Move `needless_pass_by_ref_mut`: `suspicious` -> `nursery` [Related to [this Zulip thread](https://rust-lang.zulipchat.com/#narrow/stream/257328-clippy/topic/needless_pass_by_ref_mut.20isn't.20ready.20for.20stable)] `needless_pass_by_ref_mut` has been released with some important bugs (notably having a lot of reported false positives and an ICE). So it may not be really ready for being in stable until these problems are solved. This PR changes the lint's category from `suspicious` to `nursery`, just that. changelog: none

Fix: Write access check of `prefix` and `sysconfdir` when DESTDIR is present. Improvement: Instead of repeatedly reading `DESTDIR` within each `fn prepare_dir` usage, read it once and pass it to the `fn prepare_dir`.

2023-10-20Fix a performance regression in obligation deduplication.Nicholas Nethercote-4/+4
Commit 8378487 from #114611 changed the location of an obligation deduplication step in `opt_normalize_projection_type`. This meant that deduplication stopped happening on one path where it was still necessary, causing a couple of drastic performance regressions. This commit moves the deduplication back to the old location. The good news is that #114611 had four commits and 8378487 was of minimal importance, so the perf benefits from that PR remain. Fixes #116780, #116797. (cherry picked from commit 91f2fbc867bfc31f2e103b09e605c61f1a450b33)
