LLVM had multiple ABI conformance bugs in its implementation of int128,
but clang had workarounds for these bugs that rustc lacked, causing interop problems. I wonder why they put workarounds in clang instead of fixing LLVM?!
This is a great example of one of the criticisms of LLVM, that language front ends must still implement processor-specific details themselves – iirc another example is struct layout.
