LemonBoy f2c842c94a [AtomicExpandPass][AArch64] Promote xchg with floating-point types to integer ones ... Follow the same strategy used for atomic loads/stores by converting the operands to equally-sized integer types. This change prevents the atomic expansion pass from generating illegal LL/SC pairs when targeting AArch64: `expand-atomicrmw-xchg-fp.ll` would previously instantiate intrinsics such as `llvm.aarch64.ldaxr.p0f32` that cannot be lowered.
