Clang computes the default ABI if -mabi is empty and encode it in LLVM IR module flag since D105555. For correctness, llc need to give the same target-abi (Options.MCOptions.ABIName) with ABI encoded in IR. The getSubtargetImpl already has a check for them only if Options.MCOptions.ABIName is not empty. In order to get more robustness we could have a check for explicit ABI, but now we have two different logic to compute the default ABI. The front-end ABI is defautl to the ilp32/ilp32e/lp64, and ilp32d/lp64d when hardware support for extension D. The backend ABI is default to the ilp32/ilp32e/lp64.
