As reported by @uweigand in https://reviews.llvm.org/D158883: ``` The newly added test cases in ffp-model.c fail on SystemZ, making CI red: https://lab.llvm.org/buildbot/#/builders/94/builds/16280 The root cause seems to be that by default, the SystemZ back-end targets a machine without SIMD support, and therefore vector return types are passed via implicit reference according to the ABI ``` this uses manual stores instead of vector returns.
