Why aren't you using similar code to the example link from LLVM? |

I think some APIs used there only work on LLVM 13; on 12 the code there is specific to byval: https://github.com/llvm/llvm-project/blob/llvmorg-12.0.1/llvm/lib/Transforms/Utils/ValueMapper.cpp#L901-L915 |

I think this might apply to edit: Yeah https://github.com/llvm/llvm-project/blob/fed41342a82f5a3a9201819a82bf7a48313e296b/llvm/lib/Transforms/Utils/ValueMapper.cpp#L905 has sret as well. |

LLVM 12 introduced typed byval, but CloneFunctionInto does a plain copyAttributesFrom without rewriting contained types. The ValueMapper does the correct thing for calls though, so this looks like an oversight. But it's easy enough to fix that locally for now.
