-; Note: This test is testing that the lowering for atomics matches what we
-; currently emit for non-atomics + the atomic restriction.  The presence of
-; particular lowering detail in these tests should not be read as requiring
-; that detail for correctness unless it's related to the atomicity itself.
-; (Specifically, there were reviewer questions about the lowering for halfs
-;  and their calling convention which remain unresolved.)
