Previously, only the end of pass RSS was indicated. This could easily lead one to believe that the change in RSS from one pass to the next was attributable to the second pass, when in fact it occurred between the end of the first pass and the start of the second. Also, improve alignment of columns.
…jorn3 Sync rustc_codegen_cranelift The highlight of this sync are abi compatibility with cg_llvm allowing mixing of cg_clif and cg_llvm compiled crates and switching to the x64 cranelift backend based on the new backend framework. r? ``@ghost`` ``@rustbot`` label +A-codegen +A-cranelift +T-compiler
This commit adds a new ABI to be selected via `extern "C-cmse-nonsecure-call"` on function pointers in order for the compiler to apply the corresponding cmse_nonsecure_call callsite attribute. For Armv8-M targets supporting TrustZone-M, this will perform a non-secure function call by saving, clearing and calling a non-secure function pointer using the BLXNS instruction. See the page on the unstable book for details. Signed-off-by: Hugues de Valon <hugues.devalon@arm.com>
This reverts commit bfcf97b. It causes a "can't resolve symbol" crash on macOS

It causes a miscompilation of lewton Fixes rust-lang#1142
The following functions are now unstably const: - Option::transpose - Option::flatten - Result::transpose
…, r=joshtriplett Change built-in kernel targets to be os = none throughout Whether for Rust's own `target_os`, LLVM's triples, or GNU config's, the OS-related have fields have been for code running *on* that OS, not code hat is *part* of the OS. The difference is huge, as syscall interfaces are nothing like freestanding interfaces. Kernels are (hypervisors and other more exotic situations aside) freestanding programs that use the interfaces provided by the hardware. It's *those* interfaces, the ones external to the program being built and its software dependencies, that are the content of the target. For the Linux Kernel in particular, `target_env: "gnu"` is removed for the same reason: that `-gnu` refers to glibc or GNU/linux, neither of which applies to the kernel itself. Relates to rust-lang#74247
…Jung Make some Option, Result methods unstably const The following methods are now unstably const: - Option::transpose - Option::flatten - Result::flatten While some methods for could likely be made `const` in the future, nearly all of them require something to be dropped at compile-time, which isn't currently supported. The functions listed above should have a trivial path to stabilization.
Prevent specialized ZipImpl from calling `__iterator_get_unchecked` twice with the same index Fixes rust-lang#82291 It's open for review, but conflicts with rust-lang#82289, wait before merging. The conflict involves only the new test, so it should be rather trivial to fix.
…laumeGomez Remove RefCell around `module_trait_cache` This builds on rust-lang#82018 and should not be merged before. ## Don't require a `DocContext` for `report_diagnostic` This is needed for the next commit, which needs mutable access to the `cx` from within the `decorate` closure. - Change `as_local_hir_id` to an associated function, since it only needs a `TyCtxt` - Change `source_span_for_markdown_range` to only take a `TyCtxt` ## Remove RefCell around module_trait_cache This is mostly just changing lots of functions from `&DocContext` to `&mut DocContext`.
Improve transmute docs with further clarifications Closes rust-lang#82493. Please let me know if any of the new wording sounds off, English is not my mother tongue.
…eGomez Cleanup rustdoc warnings ## Clean up error reporting for deprecated passes Using `error!` here goes all the way back to the original commit, rust-lang#8540. I don't see any reason to use logging; rustdoc should use diagnostics wherever possible. See rust-lang#81932 (comment) for further context. - Use spans for deprecated attributes - Use a proper diagnostic for unknown passes, instead of error logging - Add tests for unknown passes - Improve some wording in diagnostics ## Report that `doc(plugins)` doesn't work using diagnostics instead of `eprintln!` This also adds a test for the output. This was added in rust-lang#52194. I don't see any particular reason not to use diagnostics here, I think it was just missed in rust-lang#50541.
Fix diagnostic suggests adding type `[type error]` Fixes rust-lang#79040 ### Unresolved questions: <del>Why does this change output the diagnostic twice (`src/test/ui/79040.rs`)?</del> Thanks `````@oli-obk`````
improve offset_from docs `@thomcc` pointed out that the current docs leave it kind of unclear how one can satisfy the "no wrapping around `isize` or the address space" requirement of `offset_from`, so make the docs clearer about that. FWIW, I don't think I entirely agree with that second paragraph about large objects (that I left mostly unchanged here). LLVM, to my knowledge, fundamentally assumes that all allocations fit into an `isize::MAX`. So in that sense creating a larger allocation is simply UB. I would expect a guarantee that Rust heap allocation methods will never return allocations larger than `isize::MAX` (or rather, Rust heap allocation methods should require that the `Layout` is no larger than `isize::MAX`). However, I cannot find any such requirement documented currently. Large allocations are not mentioned at all in the allocator docs, which is quite surprising -- even if we say that such allocations are not insta-UB (which I think is incompatible with LLVM), they are still extremely footgunny since `ptr::offset`/`ptr::add` do not support offsetting by more than `isize::MAX` bytes. Furthermore, the allocator docs don't even say anything about allocations wrapping around the address space. But that is certainly something allocators must ensure never happens; we cannot expect clients to defend against this. Cc `@rust-lang/wg-allocators`

Skipped backtrace-debuginfo.rs because I think classifui overrates their helper macros. cc rust-lang#73494 r? ```@petrochenkov```
…meGomez rustdoc: Add an unstable option to print all unversioned files This allows sharing those files between different doc invocations without having to know their names ahead of time. Helps with rust-lang/docs.rs#1302. r? ````@GuillaumeGomez```` cc ````@pietroalbini```` ````@Nemo157````
…jorn3 Sync rustc_codegen_cranelift The main highlight of this sync is removal of support for the old x86 Cranelift backend. This made it possible to use native atomic instructions rather than hackishly using a global mutex. 128bit integer support has also seen a few bugfixes and performance improvements. And finally I have formatted everything using the same rustfmt config as the rest of this repo. r? ````@ghost```` ````@rustbot```` label +A-codegen +A-cranelift +T-compiler
