Turns out that there's a bad unwrap (and one more above it): rust/src/librustc_metadata/native_libs.rs Lines 174 to 176 in 8961132 Those should be matching on span like neighboring code. (cc @alexcrichton @Mark-Simulacrum)

rustc_codegen_llvm: traitification of LLVM-specific CodegenCx and Builder methods This PR is the continuation of #52461 in the grand plan of #45274 to allow for multiple codegen backends. A first attempt at this was #52987 but since @irinagpopa is no longer working on it I'm taking ownership of the PR. The changes are refactoring only and do not affect the logic of the code. Performance should not be impacted since all parametrization is done with generics (no trait objects). The `librustc_codegen_llvm` crate now contains a new folder `interfaces` that describes with traits part of how the compiler interfaces with LLVM during codegen. `CodegenCx` and `Builder` implement those traits. Many things are still missing. All the calls to LLVM are not yet under a trait, and later LLVM-agnostic code should be parametrized.
