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. -- cgit v1.2.3
