Add tests for raw-dylib with vectorcall, and fix vectorcall code generation
* Adds tests for using `raw-dylib` (#58713) with `vectorcall`.
* Fixed code generation for `vectorcall` (parameters have to be marked with `InReg`, just like `fastcall`).
* Enabled running the `raw-dylib` `fastcall` tests when using MSVC (since I had to add support in the test for running MSVC-only tests since GCC doesn't support `vectorcall`).

Enable raw-dylib for bin crates
Fixes #93842
When `raw-dylib` is used in a `bin` crate, we need to collect all of the `raw-dylib` functions, generate the import library and add that to the linker command line.
I also changed the tests so that 1) the C++ dlls are created after the Rust dlls, thus there is no chance of accidentally using them in the Rust linking process and 2) disabled generating import libraries when building with MSVC.

This is no longer used only for debugging options (e.g. `-Zoutput-width`, `-Zallow-features`).
Rename it to be more clear.

Rename the `--output-width` flag to `--diagnostic-width` as this appears
to be the preferred name within the compiler team.

Rename the `--terminal-width` flag to `--output-width` as the behaviour
doesn't just apply to terminals (and so is slightly less accurate).
Signed-off-by: David Wood <david.wood@huawei.com>
|
|
Formerly `-Zterminal-width`, `--terminal-width` allows the user or build
tool to inform rustc of the width of the terminal so that diagnostics
can be truncated.

adapt native-link-modifier-bundle test to use llvm-nm
No functional changes intended.
This updates the test case to use `llvm-nm` as an alternative to https://github.com/rust-lang/rust/pull/98424.
This fixes a test failure over at the experimental build of rustc with HEAD LLVM:
https://buildkite.com/llvm-project/rust-llvm-integrate-prototype/builds/11144#01814d0f-a46a-4c19-91cf-41e720edb6f9/684-691.
The issue is that this test uses the system nm, which may not be recent
enough to understand the bitcode produced by rustc when compiled against HEAD LLVM.
Similar to what we did for another test in https://github.com/rust-lang/rust/pull/94023.

Previously, this printed the debugging options, not the lint options,
and only handled `-Whelp`, not `-A/-D/-F`.
This also fixes a few other misc issues:
- Fix `// check-stdout` for UI tests; previously it only worked for run-fail and compile-fail tests
- Add lint headers for tool lints, not just builtin lints
- Remove duplicate run-make test

Move Derefer before Retag
_Follow up work to #96116 #95857 #95649_
This moves `Derefer` before `Retag` and creates a new `LocalInfo` called `Temp` to avoid retagging created temp values.

rustdoc: Remove .woff font files
Copying `@jsha's` great comment:
> Right now we ship 1.5MB of woff files in the rustdoc binary, and 1MB of woff2 files, for a total of 2.5MB.
>
> Per:
>
> https://caniuse.com/woff
> https://caniuse.com/woff2
>
> The only listed browser that supports woff and not woff2 is IE, which is not supported per https://github.com/rust-lang/rfcs/blob/master/text/1985-tiered-browser-support.md.
>
> I propose we stop shipping woff files and save 1.5MB from the rustdoc binary (and from each doc build).

Generate synthetic object file to ensure all exported and used symbols participate in the linking
Fix #50007 and #47384
This is the synthetic object file approach that I described in https://github.com/rust-lang/rust/pull/95363#issuecomment-1079932354, allowing all exported and used symbols to be linked while still allowing them to be GCed.
Related #93791, #95363

Improve Rustdoc UI for scraped examples with multiline arguments, fix overflow in line numbers
This PR improves a few aspects of the scrape examples feature in Rustdoc.
* Only function names and not the full call expression are highlighted.
* For call-sites with multiline arguments, the minimized code viewer will scroll to the top of the call-site rather than the middle if the argument is larger than the viewer size, ensuring that the function name is visible.
* This fixes an issue where the line numbers column had a visible x-scroll bar.

Instead of checking only the user provided sysroot or the default (when
no sysroot is provided), search user provided sysroot and then check
default sysroots for locale requested by the user.

New mir-opt deref_separator
This adds a new mir-opt that split certain derefs into this form:
`let x = (*a.b).c;` to => `tmp = a.b; let x = (*tmp).c;`
Huge thanks to ``@oli-obk`` for his patient mentoring.

Extend loading of Fluent bundles so that bundles can be loaded from the

Sysroot bundles are loaded from `$sysroot/share/locale/$locale/*.ftl`.

Enable combining `+crt-static` and `relocation-model=pic` on `x86_64-unknown-linux-gnu`
Modern `gcc` versions support `-static-pie`, and `rustc` will already fall-back to `-static` if the local `gcc` is too old (and hence this change is optimistic rather than absolute). This brings the `-musl` and `-gnu` targets to feature compatibility (albeit with different default settings).
Of note a `-static` or `-static-pie` binary based on glibc that uses NSS-backed functions (`gethostbyname` or `getpwuid` etc.) need to have access to the `libnss_X.so.2` libraries and any of their dynamic dependencies.
I wasn't sure about the `# only`/`# ignore` changes (I've not got a `gnux32` toolchain to test with hence not also enabling `-static-pie` there).

Implement raw-dylib support for windows-gnu
Add support for `#[link(kind = "raw-dylib")]` on windows-gnu targets. Work around binutils's linker's inability to read import libraries produced by LLVM by calling out to the binutils `dlltool` utility to create an import library from a temporary .DEF file; this approach is effectively a slightly refined version of `@mati865's` earlier attempt at this strategy in PR #88801. (In particular, this attempt at this strategy adds support for `#[link_ordinal(...)]` as well.)
In support of #58713.

They are also removed from the prelude as per the decision in
https://github.com/rust-lang/rust/issues/87228.
stdarch and compiler-builtins are updated to work with the new, stable
asm! and global_asm! macros.

Added the --temps-dir option
Fixes #10971.
The new `--temps-dir` option puts intermediate files in a user-specified directory. This provides a fix for the issue where parallel invocations of rustc would overwrite each other's intermediate files.
No files are kept in the intermediate directory unless `-C save-temps=yes`.
If additional files are specifically requested using `--emit asm,llvm-bc,llvm-ir,obj,metadata,link,dep-info,mir`, these will be put in the output directory rather than the intermediate directory.
This is a backward-compatible change, i.e. if `--temps-dir` is not specified, the behavior is the same as before.
