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. |
