Make inliner cycle detection a fallible process The query `mir_callgraph_cyclic` is supposed to find _all_ callees that _may_ lead to a recursive call back to the given `LocalDefId`. But that query was built using a function which recurses through the call graph and tries to locally handle hitting the recursion limit during the walk. That is wrong. If the recursion limit is encountered, the set may be incomplete and thus useless. If we hit the recursion limit the only correct thing to do is bail. Some benchmarks improve because for some functions we will bail out of the call graph walk faster. Some benchmarks regress because we do less inlining, but that is quite rare with the default recursion depth. Originally I thought this might be a fix for https://github.com/rust-lang/rust/issues/131960, but it turns out that it is _actually_ a fix for https://github.com/rust-lang/rust/issues/146998. |

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.
Why Rust?
-
Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrated with other languages.
-
Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.
-
Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).
