Proper macOS libLLVM symlink when cross compiling Follow up of #98418 When cross compiling on macOS with `llvm.link-shared` enabled, the symlink creation will fail after compiling LLVM for the target architecture, because it will attempt to create the symlink in the host LLVM directory, which was already created when being built. This commit changes the symlink path to the actual LLVM output. r? `@jyn514`

2022-07-05Rollup merge of #96814 - RalfJung:enum-repr-align, r=oli-obkGuillaume Gomez-4/+205
Fix repr(align) enum handling `enum`, for better or worse, supports `repr(align)`. That has already caused a bug in https://github.com/rust-lang/rust/issues/92464, which was "fixed" in https://github.com/rust-lang/rust/pull/92932, but it turns out that that fix is wrong and caused https://github.com/rust-lang/rust/issues/96185. So this reverts #92932 (which fixes #96185), and attempts another strategy for fixing #92464: special-case enums when doing a cast, re-using the code to load the discriminant rather than assuming that the enum has scalar layout. This works fine for the interpreter. However, #92464 contained another testcase that was previously not in the test suite -- and after adding it, it ICEs again. This is not surprising; codegen needs the same patch that I did in the interpreter. Probably this has to happen [around here](https://github.com/rust-lang/rust/blob/d32ce37a171663048a4c4a536803434e40f52bd6/compiler/rustc_codegen_ssa/src/mir/rvalue.rs#L276). Unfortunately I don't know how to do that -- the interpreter can load a discriminant from an operand, but codegen can only do that from a place. `@oli-obk` `@eddyb` `@bjorn3` any idea?

bootstrap: Allow building individual crates This aims to be as unintrusive as possible, but did still require adding a new `tail_args` field to all `Rustc` and `Std` steps. New library and compiler crates are added to the sysroot as they are built, since it's useful to have e.g. just alloc and not std. Fixes https://github.com/rust-lang/rust/issues/44293.

bootstrap.py: Always use `.exe` for Windows This ensures that it will run the Windows executable if other files in the directory (such as Linux executables) have the same file name minus the extension.

2022-07-05Rollup merge of #98776 - notriddle:notriddle/mobile-sidebar-auto-close, ↵Dylan DPC-2/+55
r=GuillaumeGomez rustdoc: improve click behavior of the source code mobile full-screen "sidebar" On desktop, if you open the source code sidebar, it stays open even when you move from page to page. It used to do the same thing on mobile, but I think that's stupid. Since the file list fills the entire screen on mobile, and you can't really do anything with the currently selected file other than dismiss the "sidebar" to look at it, it's safe to assume that anybody who clicks a file in that list probably wants the list to go away so they can see it. Split out separately from #98772

lints: mostly translatable diagnostics As lints are created slightly differently than other diagnostics, intended to try make them translatable first and then look into the applicability of diagnostic structs but ended up just making most of the diagnostics in the crate translatable (which will still be useful if I do make a lot of them structs later anyway). r? ``@compiler-errors``
2022-07-05Rollup merge of #97712 - RalfJung:untyped, r=scottmcmDylan DPC-14/+51
ptr::copy and ptr::swap are doing untyped copies The consensus in https://github.com/rust-lang/rust/issues/63159 seemed to be that these operations should be "untyped", i.e., they should treat the data as raw bytes, should work when these bytes violate the validity invariant of `T`, and should exactly preserve the initialization state of the bytes that are being copied. This is already somewhat implied by the description of "copying/swapping size*N bytes" (rather than "N instances of `T`"). The implementations mostly already work that way (well, for LLVM's intrinsics the documentation is not precise enough to say what exactly happens to poison, but if this ever gets clarified to something that would *not* perfectly preserve poison, then I strongly assume there will be some way to make a copy that *does* perfectly preserve poison). However, I had to adjust `swap_nonoverlapping`; after ``@scottmcm's`` [recent changes](https://github.com/rust-lang/rust/pull/94212), that one (sometimes) made a typed copy. (Note that `mem::swap`, which works on mutable references, is unchanged. It is documented as "swapping the values at two mutable locations", which to me strongly indicates that it is indeed typed. It is also safe and can rely on `&mut T` pointing to a valid `T` as part of its safety invariant.) On top of adding a test (that will be run by Miri), this PR then also adjusts the documentation to indeed stably promise the untyped semantics. I assume this means the PR has to go through t-libs (and maybe t-lang?) FCP. Fixes https://github.com/rust-lang/rust/issues/63159

Change enum->int casts to not go through MIR casts. follow-up to https://github.com/rust-lang/rust/pull/96814 this simplifies all backends and even gives LLVM more information about the return value of `Rvalue::Discriminant`, enabling optimizations in more cases.

Add method to mutate MIR body without invalidating CFG caches. In addition to adding this method, a handful of passes are updated to use it. There's still quite a few passes that could in principle make use of this as well, but do not at the moment because they use `VisitorMut` or `MirPatch`, which needs additional support for this. The method name is slightly unwieldy, but I don't expect anyone to be writing it a lot, and at least it says what it does. If anyone has a suggestion for a better name though, would be happy to rename. r? rust-lang/mir-opt
