2022-12-08Add LLVM KCFI support to the Rust compilerRamon de C Valle-1/+1
This commit adds LLVM Kernel Control Flow Integrity (KCFI) support to the Rust compiler. It initially provides forward-edge control flow protection for operating systems kernels for Rust-compiled code only by aggregating function pointers in groups identified by their return and parameter types. (See llvm/llvm-project@cff5bef.) Forward-edge control flow protection for C or C++ and Rust -compiled code "mixed binaries" (i.e., for when C or C++ and Rust -compiled code share the same virtual address space) will be provided in later work as part of this project by identifying C char and integer type uses at the time types are encoded (see Type metadata in the design document in the tracking issue #89653). LLVM KCFI can be enabled with -Zsanitizer=kcfi. Co-authored-by: bjorn3 <17426603+bjorn3@users.noreply.github.com>
2022-09-25Rollup merge of #101997 - cuviper:drop-legacy-pm, r=nikicfee1-dead-1/+1
Remove support for legacy PM This removes support for optimizing with LLVM's legacy pass manager, as well as the unstable `-Znew-llvm-pass-manager` option. We have been defaulting to the new PM since LLVM 13 (except for s390x that waited for 14), and LLVM 15 removed support altogether. The only place we still use the legacy PM is for writing the output file, just like `llc` does. cc #74705 r? ``@nikic``

2022-07-20Add ShadowCallStack SupportIvan Lozano-1/+1
Adds support for the LLVM ShadowCallStack sanitizer.
2022-05-24Add support for embedding pretty printers via the `#[debugger_visualizer]` ↵ridwanabdillahi-5/+15
attribute. Add tests for embedding pretty printers and update documentation. Ensure all error checking for `#[debugger_visualizer]` is done up front and not when the `debugger_visualizer` query is run. Clean up potential ODR violations when embedding pretty printers into the `__rustc_debug_gdb_scripts_section__` section. Respond to PR comments and update documentation.
2022-05-03Add support for a new attribute `#[debugger_visualizer]` to support ↵ridwanabdillahi-0/+27
embedding debugger visualizers into a generated PDB. Cleanup `DebuggerVisualizerFile` type and other minor cleanup of queries. Merge the queries for debugger visualizers into a single query. Revert move of `resolve_path` to `rustc_builtin_macros`. Update dependencies in Cargo.toml for `rustc_passes`. Respond to PR comments. Load visualizer files into opaque bytes `Vec<u8>`. Debugger visualizers for dynamically linked crates should not be embedded in the current crate. Update the unstable book with the new feature. Add the tracking issue for the debugger_visualizer feature. Respond to PR comments and minor cleanups.
2022-03-07Do not allow `#[rustc_legacy_const_generics]` on methodsChayim Refael Friedman-3/+16
It caused an ICE since `item` was `None`.

Adds support for the LLVM MemTagSanitizer.
2021-09-25Check for macros in built-in attributes that don't support them.Eric Huss-0/+15
2021-08-21Remove `Session.used_attrs` and move logic to `CheckAttrVisitor`Aaron Hill-10/+3
Instead of updating global state to mark attributes as used, we now explicitly emit a warning when an attribute is used in an unsupported position. As a side effect, we are to emit more detailed warning messages (instead of just a generic "unused" message). `Session.check_name` is removed, since its only purpose was to mark the attribute as used. All of the callers are modified to use `Attribute.has_name` Additionally, `AttributeType::AssumedUsed` is removed - an 'assumed used' attribute is implemented by simply not performing any checks in `CheckAttrVisitor` for a particular attribute. We no longer emit unused attribute warnings for the `#[rustc_dummy]` attribute - it's an internal attribute used for tests, so it doesn't mark sense to treat it as 'unused'. With this commit, a large source of global untracked state is removed.

2021-03-16Use delay_span_bug instead of panic in layout_scalar_valid_rangeTomasz Miąsko-1/+14
83054 introduced validation of scalar range attributes, but panicking code that uses the attribute remained reachable. Use `delay_span_bug` instead to avoid the ICE.

2019-10-17Plugins deprecation: don’t suggest simply removing the attributeSimon Sapin-2/+2
Building Servo with a recent Nightly produces: ```rust warning: use of deprecated attribute `plugin`: compiler plugins are deprecated. See https://github.com/rust-lang/rust/issues/29597 --> components/script/lib.rs:14:1 | 14 | #![plugin(script_plugins)] | ^^^^^^^^^^^^^^^^^^^^^^^^^^ help: remove this attribute | = note: `#[warn(deprecated)]` on by default ``` First, linking to https://github.com/rust-lang/rust/issues/29597 is not ideal since there is pretty much no discussion there of the deprecation and what can be used instead. This PR changes the link to the deprecation PR which does have more discussion. Second, the “remove this attribute” suggestion is rather unhelpful. Just because a feature is deprecated doesn’t mean that simply removing its use without a replacement is acceptable. In the case of custom lint, there is no replacement available. Prefixing a message with “help:” when telling users that they’re screwed honestly feels disrespectful. This PR also changes the message to be more factual.

Function signatures with the `variadic` member set are actually C-variadic functions. Make this a little more explicit by renaming the `variadic` boolean value, `c_variadic`.

This adds a suggestion to the `invalid_crate_types` lint. The suggestion is based on the Levenshtein distance to existing crate types. If no suggestion is found it will show the lint without any suggestions.
