[llvm-dev] IR to binary address mapping

[mayuyu.io via llvm-dev]

In theory that’s not exactly possible/accurate. Due to various operations in the Backend like Instruction Legalization, one IR instruction might got emitted into multiple assembly instruction, for example

I think the binary is generated by clang and llvm. I think there definitely is some information about the mapping relationship between LLVM IR and the target binary address. Do anyone has suggestions? Many Thanks
