mitigate MSVC alignment issue on x86-32 This implements mitigation for rust-lang/rust#112480 by stopping to emit `align` attributes on loads and function arguments when building for a win32 MSVC target. MSVC is known to not properly align `u64` and similar types, and claiming to LLVM that everything is properly aligned increases the chance that this will cause problems. Of course, the misalignment is still a bug, but we can't fix that bug, only MSVC can. Also add an errata note to the platform support page warning users about this known problem. try-job: `i686-msvc*`
Mention average in midpoint documentations Added a mention to "average" in midpoint documentations and as well as some `#[doc(alias = "average")]`[^1]. This is done to improve the discoverability of the function. [^1]: https://docs.rs/num-integer/latest/num_integer/trait.Average.html#tymethod.average_floor
…orn3 minicore: Have `//@ add-core-stubs` also imply `-Cforce-unwind-tables=yes` To preserve CFI directives in assembly tests, as `//@ add-core-stubs` already imply `-C panic=abort`. This is a blocker for rust-lang/rust#140037 (comment). cc ```@RalfJung``` r? ```@bjorn3```
triagebot: label minicore changes w/ `A-test-infra-minicore` and ping jieyouxu on changes Just routine triagebot labelling/mentioning changes. r? ```@ghost```
Remove comment about handling non-global where bounds with corresponding projection This comment is no longer relevant since we only assemble rigid projections if no param-env candidates hold. Also remove a stray comment from the old solver. r? lcnr
…=jieyouxu Revert overzealous parse recovery for single colons in paths Basically manually reverts #136808, cc ``@chenyukang`` ``@estebank.`` Reopens #129273. Fixes [after beta backport] #140227.

Revert compiletest new-executor, to re-land without download-rustc Revert <rust-lang/rust#139998> because the original merge triggered download-rustc, which messes with test metrics and prevents us from properly comparing them before/after the change. The plan is to re-land this PR as-is, combined with a trivial compiler change to avoid download-rustc and get proper test metrics for comparison. This reverts commit be181dd75c83d72fcc95538e235768bc367b76b9, reversing changes made to 645d0ad2a4f145ae576e442ec5c73c0f8eed829b. r? ghost
Allow out of order dep graph node encoding This allows out of order dep graph node encoding by also encoding the index instead of using the file node order as the index. `MemEncoder` is also brought back to life and used for encoding. Both of these are done to enable thread-local encoding of dep graph nodes. This is based on rust-lang/rust#139636.
[compiletest] Parallelize test discovery Certain filesystems are slow to service individual read requests, but can service many in parallel. This change brings down the time to run a single cached test on one of those filesystems from 40s to about 8s.
check types of const param defaults fixes #139643 by checking that the type of a const parameter default matches the type of the parameter as long as both types are fully concrete r? `@BoxyUwU`
Correctly display stdout and stderr in case a doctest is failing Fixes rust-lang/rust#140289. Since the doctest is actually running itself, we need to handle the output directly inside it. cc `@fmease` r? `@notriddle`
