If a function was instrumented for coverage, but all of its coverage statements have been removed by later MIR transforms, it should be treated as "unused" even if the compiler generates an unreachable stub for it.
This enables KCFI-based testing for all the CFI run-pass tests in the suite today. We can add the test header on top of in-flight CFI tests once they land. It also enables KCFI as a sanitizer for x86_64 and aarch64 Linux to make this possible. The sanitizer should likely be available for all aarch64, x86_64, and riscv targets, but that isn't critical for initial testing.
Previously, the documentation for a variant appeared after the documentation for each of its fields. This was inconsistent with structs and unions, and made little sense on its own; fields are subordinate to variants and should therefore appear later in the documentation.
…nkov Implement `-L KIND=@RUSTC_BUILTIN/...` Implements rust-lang/compiler-team#659
coverage: Re-enable `UnreachablePropagation` for coverage builds This is a sequence of 3 related changes: - Clean up the existing code that scans for unused functions - Detect functions that were instrumented for coverage, but have had all their coverage statements removed by later MIR transforms (e.g. `UnreachablePropagation`) - Re-enable `UnreachablePropagation` in coverage builds Because we now detect functions that have lost their coverage statements, and treat them as unused, we don't need to worry about `UnreachablePropagation` removing all of those statements. This is demonstrated by `tests/coverage/unreachable.rs`. Fixes rust-lang#116171.
…ol, r=oli-obk Make `TyCtxt::coroutine_layout` take coroutine's kind parameter For coroutines that come from coroutine-closures (i.e. async closures), we may have two kinds of bodies stored in the coroutine; one that takes the closure's captures by reference, and one that takes the captures by move. These currently have identical layouts, but if we do any optimization for these layouts that are related to the upvars, then they will diverge -- e.g. rust-lang#120168 (comment). This PR relaxes the assertion I added in rust-lang#121122, and instead make the `TyCtxt::coroutine_layout` method take the `coroutine_kind_ty` argument from the coroutine, which will allow us to differentiate these by-move and by-ref bodies.
CFI: Enable KCFI testing of run-pass tests This enables KCFI-based testing for all the CFI run-pass tests in the suite today. We can add the test header on top of in-flight CFI tests once they land. This is becoming more important as we get closer to leveraging CFI's multiple type attachment feature, as that is where the implementations will have a divergence. It also enables KCFI as a sanitizer for x86_64 and aarch64 Linux to make this possible. The sanitizer should likely be available for all aarch64, x86_64, and riscv targets, but that isn't critical for initial testing.
