Exception for specific cases like linting, additional passes should be going into the module pass manager (even if they are function passes). The separate function pass manager is only used for very early optimization passes. Rather than apparending passes to the MPM, use the OptimizerLast and EnabledOnOptLevel0 pass manager builder extension hooks, which allow adding passes directly before finalization (alias canonicalization and name-anon-globals). The main effect and purpose of this change is to add sanitizer passes at the end of the pipeline, which is where they belong. In LLVM 9 the address sanitizer can't be used as a pass in the early function pass manager, because it has a dependence on a module-level analysis pass. |

The codegen crate contains the code to convert from MIR into LLVM IR,
and then from LLVM IR into machine code. In general it contains code
that runs towards the end of the compilation process.
For more information about how codegen works, see the rustc guide.
