But I'd think they ought to work with any -mfpu= option supporting half-precision instructions - that is, vfpv3-fp16, vfpv3-d16-fp16, vfpv3xd-fp16, neon-fp16, vfpv4, vfpv4-d16, fpv4-sp-d16, neon-vfpv4 (anything with "true" in the last field in arm-fpus.def; for the testsuite, you can probably suppose anything -mfpu=*fp16*, -mfpu=*fpv[4-9]*, -mfpu=*fpv[1-9][0-9]*). -- Joseph S.
