2025-06-27Rollup merge of #139858 - oli-obk:new-const-traits-syntax, r=fee1-deadMatthias Krüger-22/+21
New const traits syntax This PR only affects the AST and doesn't actually change anything semantically. All occurrences of `~const` outside of libcore have been replaced by `[const]`. Within libcore we have to wait for rustfmt to be bumped in the bootstrap compiler. This will happen "automatically" (when rustfmt is run) during the bootstrap bump, as rustfmt converts `~const` into `[const]`. After this we can remove the `~const` support from the parser Caveat discovered during impl: there is no legacy bare trait object recovery for `[const] Trait` as that snippet in type position goes down the slice /array parsing code and will error r? ``@fee1-dead`` cc ``@nikomatsakis`` ``@traviscross`` ``@compiler-errors``

2025-06-27Insert checks for enum discriminants when debug assertions are enabledBastian Kersting-1/+1
Similar to the existing nullpointer and alignment checks, this checks for valid enum discriminants on creation of enums through unsafe transmutes. Essentially this sanitizes patterns like the following: ```rust let val: MyEnum = unsafe { std::mem::transmute<u32, MyEnum>(42) }; ``` An extension of this check will be done in a follow-up that explicitly sanitizes for extern enum values that come into Rust from e.g. C/C++. This check is similar to Miri's capabilities of checking for valid construction of enum values. This PR is inspired by saethlin@'s PR https://github.com/rust-lang/rust/pull/104862. Thank you so much for keeping this code up and the detailed comments! I also pair-programmed large parts of this together with vabr-g@.

r=lolbinarycat [rustdoc] Do not emit redundant_explicit_links lint if the doc comment comes from expansion Fixes https://github.com/rust-lang/rust/issues/141553. The problem was that we change the context for the attributes in some cases to get better error output, preventing us to detect if the attribute comes from expansion. Most of the changes are about keeping track of the "does this span comes from expansion" information. r? ```@Manishearth```
2025-06-26Rollup merge of #141311 - folkertdev:tidy-natural-sort, r=jieyouxuMatthias Krüger-2/+204
make `tidy-alphabetical` use a natural sort The idea here is that these lines should be correctly sorted, even though a naive string comparison would say they are not: ``` foo2 foo10 ``` This is the ["natural sort order"](https://en.wikipedia.org/wiki/Natural_sort_order). There is more discussion in [#t-compiler/help > tidy natural sort](https://rust-lang.zulipchat.com/#narrow/channel/182449-t-compiler.2Fhelp/topic/tidy.20natural.20sort/with/519111079) Unfortunately, no standard sorting tools are smart enough to to this automatically (casting some doubt on whether we should make this change). Here are some sort outputs: ``` > cat foo.txt | sort foo foo1 foo10 foo2 mp mp1e2 np", np1e2", > cat foo.txt | sort -n foo foo1 foo10 foo2 mp mp1e2 np", np1e2", > cat foo.txt | sort -V foo foo1 foo2 foo10 mp mp1e2 np1e2", np", ``` Disappointingly, "numeric" sort does not actually have the behavior we want. It only sorts by numeric value if the line starts with a number. The "version" sort looks promising, but does something very unintuitive if you look at the final 4 values. None of the other options seem to have the desired behavior in all cases: ``` -b, --ignore-leading-blanks ignore leading blanks -d, --dictionary-order consider only blanks and alphanumeric characters -f, --ignore-case fold lower case to upper case characters -g, --general-numeric-sort compare according to general numerical value -i, --ignore-nonprinting consider only printable characters -M, --month-sort compare (unknown) < 'JAN' < ... < 'DEC' -h, --human-numeric-sort compare human readable numbers (e.g., 2K 1G) -n, --numeric-sort compare according to string numerical value -R, --random-sort shuffle, but group identical keys. See shuf(1) --random-source=FILE get random bytes from FILE -r, --reverse reverse the result of comparisons --sort=WORD sort according to WORD: general-numeric -g, human-numeric -h, month -M, numeric -n, random -R, version -V -V, --version-sort natural sort of (version) numbers within text ``` r? ```@Noratrieb``` (it sounded like you know this code?)

Add PrintTAFn flag for targeted type analysis printing ## Summary This PR adds a new `PrintTAFn` flag to the `-Z autodiff` option that allows printing type analysis information for a specific function, rather than all functions. ## Changes ### New Flag - Added `PrintTAFn=<function_name>` option to `-Z autodiff` - Usage: `-Z autodiff=Enable,PrintTAFn=my_function_name` ### Implementation Details - **Rust side**: Added `PrintTAFn(String)` variant to `AutoDiff` enum - **Parser**: Updated `parse_autodiff` to handle `PrintTAFn=<function_name>` syntax with proper error handling - **FFI**: Added `set_print_type_fun` function to interface with Enzyme's `FunctionToAnalyze` command line option - **Documentation**: Updated help text and documentation for the new flag ### Files Modified - `compiler/rustc_session/src/config.rs`: Added `PrintTAFn(String)` variant - `compiler/rustc_session/src/options.rs`: Updated parser and help text (now shows `PrintTAFn` in the list) - `compiler/rustc_codegen_llvm/src/llvm/enzyme_ffi.rs`: Added FFI function and static variable - `compiler/rustc_codegen_llvm/src/back/lto.rs`: Added handling for new flag - `src/doc/rustc-dev-guide/src/autodiff/flags.md`: Updated documentation - `src/doc/unstable-book/src/compiler-flags/autodiff.md`: Updated documentation ## Testing The flag can be tested with: ```bash rustc +enzyme -Z autodiff=Enable,PrintTAFn=square test.rs ``` This will print type analysis information only for the function named "square" instead of all functions. ## Error Handling The parser includes proper error handling: - Missing argument: `PrintTAFn` without `=<function_name>` will show an error - Unknown options: Invalid autodiff options will be reported r? ```@ZuseZ4```
