linker: Report linker flavors incompatible with the current target

Previously they would be reported as link time errors about unknown linker options

Add cross-language LLVM CFI support to the Rust compiler

2023-05-03T22:41:29+00:00

This commit adds cross-language LLVM Control Flow Integrity (CFI) support to the Rust compiler by adding the `-Zsanitizer-cfi-normalize-integers` option to be used with Clang `-fsanitize-cfi-icall-normalize-integers` for normalizing integer types (see https://reviews.llvm.org/D139395). It provides 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). For more information about LLVM CFI and cross-language LLVM CFI support for the Rust compiler, see design document in the tracking issue #89653. Cross-language LLVM CFI can be enabled with -Zsanitizer=cfi and -Zsanitizer-cfi-normalize-integers, and requires proper (i.e., non-rustc) LTO (i.e., -Clinker-plugin-lto).

Rollup merge of #107489 - compiler-errors:non_lifetime_binders, r=cjgillot

2023-02-16T23:19:34+00:00

Implement partial support for non-lifetime binders This implements support for non-lifetime binders. It's pretty useless currently, but I wanted to put this up so the implementation can be discussed. Specifically, this piggybacks off of the late-bound lifetime collection code in `rustc_hir_typeck::collect::lifetimes`. This seems like a necessary step given the fact we don't resolve late-bound regions until this point, and binders are sometimes merged. Q: I'm not sure if I should go along this route, or try to modify the earlier nameres code to compute the right bound var indices for type and const binders eagerly... If so, I'll need to rename all these queries to something more appropriate (I've done this for `resolve_lifetime::Region` -> `resolve_lifetime::ResolvedArg`) cc rust-lang/types-team#81 r? `@ghost`

Emit an error if -Z instrument-xray is not supported

2023-02-09T03:29:40+00:00

This is somewhat important because LLVM enables the pass based on target architecture, but support by the target OS also matters. For example, XRay attributes are processed by codegen for macOS targets, but Apple linker fails to process relocations in XRay data sections, so the feature as a whole is not supported there for the time being.
