The maximum discriminator value LLVM can currently encode is 2^12. If macro use results in more than 2^12 calls to the same function attributed to the same callsite, and those calls are MIR-inlined, we will require more than the maximum discriminator value to completely represent the debug information. Once we reach that point drop the debug info instead. |

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 dev guide.
