Implement declarative (`macro_rules!`) derive macros (RFC 3698) This is a draft for review, and should not be merged yet. This is layered atop rust-lang/rust#145153 , and has only two additional commits atop that. The first handles parsing and provides a test for various parse errors. The second implements expansion and handles application. This implements RFC 3698, "Declarative (`macro_rules!`) derive macros". Tracking issue: rust-lang/rust#143549 This has one remaining issue, which I could use some help debugging: in `tests/ui/macros/macro-rules-derive-error.rs`, the diagnostics for `derive(fn_only)` (for a `fn_only` with no `derive` rules) and `derive(ForwardReferencedDerive)` both get emitted twice, as a duplicate diagnostic. From what I can tell via adding some debugging code, `unresolved_macro_suggestions` is getting called twice from `finalize_macro_resolutions` for each of them, because `self.single_segment_macro_resolutions` has two entries for the macro, with two different `parent_scope` values. I'm not clear on why that happened; it doesn't happen with the equivalent code using attrs. I'd welcome any suggestions for fixing this.
Fix `-Zregparm` for LLVM builtins
This fixes the issue where `-Zregparm=N` was not working correctly when calling LLVM intrinsics
By default on `x86-32`, arguments are passed on the stack. The `-Zregparm=N` flag allows the first `N` arguments to be passed in registers instead.
When calling intrinsics like `memset`, LLVM still passes parameters on the stack, which prevents optimizations like tail calls.
As proposed by ````@tgross35,```` I fixed this by setting the `NumRegisterParameters` LLVM module flag to `N` when the `-Zregparm=N` is set.
```rust
// compiler/rust_codegen_llvm/src/context.rs#375-382
if let Some(regparm_count) = sess.opts.unstable_opts.regparm {
llvm::add_module_flag_u32(
llmod,
llvm::ModuleFlagMergeBehavior::Error,
"NumRegisterParameters",
regparm_count,
);
}
```
[Here](https://rust.godbolt.org/z/YMezreo48) is a before/after compiler explorer.
Here is the final result for the code snippet in the original issue:
```asm
entrypoint:
push esi
mov esi, eax
mov eax, ecx
mov ecx, esi
pop esi
jmp memset ; Tail call parameters in registers
```
Fixes: rust-lang/rust#145271
Add codegen test for issue 122734 Closes rust-lang/rust#122734
cg_llvm: Use LLVM-C bindings for `LLVMSetTailCallKind`, `LLVMGetTypeKind` This PR replaces two existing `LLVMRust` bindings with equivalent calls to the LLVM-C API. For `LLVMGetTypeKind`, we avoid the UB hazard by declaring the foreign function to return `RawEnum<TypeKind>` (which is a wrapper around `u32`), and then perform checked conversion from `u32` to `TypeKind`.
Add static glibc to the nix dev shell This fixes `tests/ui/process/nofile-limit.rs` which fails to link on nixos for me without this change.
…ieyouxu Speedup `copy_src_dirs` in bootstrap I was kinda offended by how slow it was. Just the `copy_src_dirs` part took ~3s locally in the `x dist rustc-src` step. In release mode it was just 1s, but that's kind of cheating (I wonder if we should build bootstrap in release mode on CI though...). Did some basic optimizations to bring it down to ~1s also in debug mode. Maybe it's overkill, due to rust-lang/rust#145455. Up to you whether we should merge it or close it :) r? `````````@jieyouxu`````````
Fix typo in doc for library/std/src/fs.rs#set_permissions "privalage" -> "privilege". Was reading the docs and have noticed this.
…jdonszelmann Fix deprecation attributes on foreign statics r? ````````@jdonszelmann```````` Fixes rust-lang/rust#145437
Automatic Rustup
This change implements the #[sanitize(..)] attribute, which opts to
replace the currently unstable #[no_sanitize]. Essentially the new
attribute works similar as #[no_sanitize], just with more flexible
options regarding where it is applied. E.g. it is possible to turn
a certain sanitizer either on or off:
`#[sanitize(address = "on|off")]`
This attribute now also applies to more places, e.g. it is possible
to turn off a sanitizer for an entire module or impl block:
```rust
\#[sanitize(address = "off")]
mod foo {
fn unsanitized(..) {}
#[sanitize(address = "on")]
fn sanitized(..) {}
}
\#[sanitize(thread = "off")]
impl MyTrait for () {
...
}
```
This attribute is enabled behind the unstable `sanitize` feature.
This removes the #[no_sanitize] attribute, which was behind an unstable feature named no_sanitize. Instead, we introduce the sanitize attribute which is more powerful and allows to be extended in the future (instead of just focusing on turning sanitizers off). This also makes sanitize(kernel_address = ..) attribute work with -Zsanitize=address To do it the same as how clang disables address sanitizer, we now disable ASAN on sanitize(kernel_address = "off") and KASAN on sanitize(address = "off"). The same was added to clang in https://reviews.llvm.org/D44981.
Implement the accepted ACP for methods that find the index of the least significant (lowest) and most significant (highest) set bit in an integer for signed, unsigned, and NonZero types. Also add unit tests for all these types.

libstd: init(): dup() subsequent /dev/nulls instead of opening them again
This will be faster, and also it deduplicates the code so win/win
The dup() is actually infallible here. But whatever.
Before:
```

…-abis-arm, r=RalfJung,davidtwco c-variadic: multiple ABIs in the same program for arm similar to rust-lang/rust#144379, but for arm, requested in rust-lang/rust#144066. Quoting rust-lang/reference#1946 (comment) > `"aapcs"` specifically refers to the soft-float ABI where floating-point values are passed in integer registers. However for c-variadic functions, `aapcs` behaves the same as `C`: https://github.com/ARM-software/abi-aa/blob/main/aapcs32/aapcs32.rst#65parameter-passing > A variadic function is always marshaled as for the base standard. https://github.com/ARM-software/abi-aa/blob/main/aapcs32/aapcs32.rst#7the-standard-variants > This section applies only to non-variadic functions. For a variadic function the base standard is always used both for argument passing and result return. --- I also noticed that rustc currently emit more instructions than clang for c-variadic functions on arm, see https://godbolt.org/z/hMce9rnTh. I'll fix that separately. (edit: rust-lang/rust#144549) try-job: armhf-gnu r? `@RalfJung`
…esleywiser aarch64-nintendo-switch-freestanding - Enable CPU features that are always available in a live system (crypto instructions, plus explicit NEON). ~~While some NEON and crypto features may not be supported on the Nintendo Switch at boot (e.g. on the a53 cores) and this has not been tested, the features will _always_ be available if running as a sysmodule or homebrew application under Horizon/Atmosphere.~~ EDIT: the a53 cores are fused out, these features are always available. This has been tested with local tools personally, as well as building [emuiibo](https://github.com/XorTroll/emuiibo) as it uses both `sha` and `aes` primitives. This was tested using inline assembly in previous versions, and in current versions by using the `aes`, `ctr`, `hmac`, and `sha2` crates. r? `@jam1garner` This ended up being much delayed from our discussions about updating this. I tested a number of individual features such as the `aes` and `sha2` target-features directly to avoid a warning message with the `crypto` feature, but that appears to be caused by rust-lang/rust#96472 and is not actually an issue. There is also a decision to make here about explicitly enabling the `neon` feature. I am in favor of it to be explicit, but it is not necessary as it is already enabled by the `v8a` and `crypto` features. I will defer to your decision as it does not change the actual instructions available for codegen.

…twco Refactor attribute parsing to improve ergonomics and some diagnostics
Gate static closures behind a parser feature I'd like to gate `static ||` closures behind a feature gate, since we shouldn't allow people to take advantage of this syntax if it's currently unstable. Right now, since it's only rejected after ast lowering, it's accessible to macros. Let's crater this to see if we can claw it back without breaking anyone's code.
Add two tidy dependency checks Deny duplicate dependencies for the standard library as it would almost certainly bloat executables. And deny proc-macro dependencies for the standard library as they would break cross-compilation.

rustc_expand: ensure stack in `InvocationCollector::visit_expr` In Fedora, when we built rustc with PGO on ppc64le, we started failing the test `issue-74564-if-expr-stack-overflow.rs`. This could also be reproduced on other arches by setting a smaller `RUST_MIN_STACK`, so it's probably just unlucky that ppc64le PGO created a large stack frame somewhere in this recursion path. Adding an `ensure_sufficient_stack` solves the stack overflow. Historically, that test and its fix were added in rust-lang/rust#74708, which was also an `ensure_sufficient_stack` in this area of code at the time. However, the refactor in rust-lang/rust#92573 basically left that to the general `MutVisitor`, and then rust-lang/rust#142240 removed even that ensure call. It may be luck that our tier-1 tested targets did not regress the original issue across those refactors.
