Stylize `*-lynxos178-*` target maintainer handle to make it easier to copy/paste Apparently I forgot to submit this branch I had lying around. Noticed while reviewing Tier 3 target platform support pages. In the same style as rust-lang/rust#139028.
2025-08-03Rollup merge of #144738 - bjorn3:remove_omit_gdb_pretty_printer_section, ↵Samuel Tardieu-0/+1
r=jieyouxu Remove the omit_gdb_pretty_printer_section attribute Disabling loading of pretty printers in the debugger itself is more reliable. Before this commit the .gdb_debug_scripts section couldn't be included in dylibs or rlibs as otherwise there is no way to disable the section anymore without recompiling the entire standard library.

2025-07-30Rollup merge of #143465 - kornelski:extern-name, r=petrochenkovSamuel Tardieu-0/+6
Support multiple crate versions in --extern-html-root-url Rustdoc's `--extern-html-root-url` used to use `tcx.crate_name()` to identify crates, but that used crates' internal names from their metadata, instead of names given to them in `--extern`. That was confusing, because both `--extern…` arguments seem related and use similar syntax. Crucially, this didn't work correctly with Cargo's package aliases or multiple versions of crates. `sess.opts.externs` lacks `CrateNum`, and `Resolver.extern_prelude` gets destroyed before `rustdoc` has a chance to see it, so I've had to save this mapping in `CStore`. Just in case, I've kept the previous mapping by crate name as a fallback for crates that weren't matched by their extern name. Fixes rust-lang/rust#76296

2025-07-25Revise content on lang feature processesTravis Cross-263/+333
Let's revise both the new content in this PR as well as the remaining text in the relevant chapters so as to better describe our current processes related to language features and their stabilizations. For the new stabilization report template, based on reviewing its early use and well as reviewing earlier stabilization reports, we've revised it editorially and added questions designed to capture additional details to which we commonly want people to speak.

2025-07-22Rollup merge of #142097 - ZuseZ4:offload-host1, r=oli-obk许杰友 Jieyou Xu (Joe)-0/+8
gpu offload host code generation r? ghost This will generate most of the host side code to use llvm's offload feature. The first PR will only handle automatic mem-transfers to and from the device. So if a user calls a kernel, we will copy inputs back and forth, but we won't do the actual kernel launch. Before merging, we will use LLVM's Info infrastructure to verify that the memcopies match what openmp offloa generates in C++. `LIBOMPTARGET_INFO=-1 ./my_rust_binary` should print that a memcpy to and later from the device is happening. A follow-up PR will generate the actual device-side kernel which will then do computations on the GPU. A third PR will implement manual host2device and device2host functionality, but the goal is to minimize cases where a user has to overwrite our default handling due to performance issues. I'm trying to get a full MVP out first, so this just recognizes GPU functions based on magic names. The final frontend will obviously move this over to use proper macros, like I'm already doing it for the autodiff work. This work will also be compatible with std::autodiff, so one can differentiate GPU kernels. Tracking: - https://github.com/rust-lang/rust/issues/131513
