D158169 <https://reviews.llvm.org/D158169> landed today, I confirmed that the current main (with D158169 <https://reviews.llvm.org/D158169>) makes Clang <-> GCC works but LLVM still fails without this patch.

Doesn't clang just wind up going through the same tablegen as LLVM, so it makes sense that both would be fixed?

You mean this patch only right - how does that work? Looking closer at your comments there, it doesn't seem like `i128` changes would affect anything if the `f128` return alignment is the source of the problem.
