I'm not aware of any other target that passes structs the same way. RISC-V fails the testcase because it will decompose a struct containing only floats into fields and pass the fields as scalars. IA-64 and Aarch64 have support for HFA (homogenous FP aggregates), but this case doesn't qualify as an HFA because of the empty struct, and hence this case gets no special treatment for those targets and isn't broken.
