LLVM does not expect to ever see multiple dbg_declares for the same variable at the same location with different values. proc-macros make it possible for arbitrary code, including multiple calls that get inlined, to happen at any given location in the source code. Add discriminators when that happens so these locations are different to LLVM. This may interfere with the AddDiscriminators pass in LLVM, which is added by the unstable flag -Zdebug-info-for-profiling. Fixes #131944 |

This directory currently contains some LLVM support code. This will generally be sent upstream to LLVM in time; for now it lives here. NOTE: the LLVM C++ ABI is subject to between-version breakage and must *never* be exposed to Rust. To allow for easy auditing of that, all Rust-exposed types must be typedef-ed as "LLVMXyz", or "LLVMRustXyz" if they were defined here. Functions that return a failure status and leave the error in the LLVM last error should return an LLVMRustResult rather than an int or anything to avoid confusion. When translating enums, add a single `Other` variant as the first one to allow for new variants to be added. It should abort when used as an input. All other types must not be typedef-ed as such.
