Currently this all assumes that we have the FPCR.EBF=3D0 semantics. For FPCR.EBF=3D1 we will need to: * call a different routine to bfdotadd() because we need to do a fused multiply-add rather than separate multiply and add steps * use a different float_status that honours the FPCR rounding mode and denormal-flushing fields * pass in an extra float_status that has been set up to perform round-to-odd rounding To prepare for this, refactor all the callsites so that instead of for (...) { x =3D bfdotadd(...); } they are: float_status fpst, fpst_odd; if (is_ebf(env, &fpst, &fpst_odd)) { for (...) { x =3D bfdotadd_ebf(..., &fpst, &fpst_odd); } } else { for (...) { x =3D bfdotadd(..., &fpst); } } For the moment the is_ebf() function always returns false, sets up fpst for EBF=3D0 semantics and never sets up fpst_odd; bfdotadd_ebf() will assert if called. We'll fill in the handling for EBF=3D1 in the next commit. This change should be a zero-behaviour-change refactor.

Replace it with g_assert_not_reached(). (This is different from the other cpu_thread_fn for e.g. MTTCG or for the KVM accelerator -- those can exit, if the vCPU they are responsible for is unplugged. But the RR cpu thread fn handles all CPUs in the system in a round-robin way, so even if one is unplugged it keeps looping.)

This is no change in behaviour for guests, because if they simply ignore stage 2 and never configure it then it has no effect. For the usual backwards compatibility reasons we enable this only for machine types starting with 9.2. (Note that the SMMU is disabled by default on the virt board and is only created if the user passes the 'iommu=3Dsmmuv3' machine option.)

The architecture says that bit 6 is the 'op' bit, which is 1 for VFNMA and 0 for VFNMS, but we label these two lines of decode the other way around. This doesn't cause any user-visible problem because in the handling of these functions in translate-vfp.c we give VFNMA the behaviour specified for VFNMS and vice-versa, but it's confusing when reading the code. Switch the names of the VFP VFNMA and VFNMS instructions in the decode file and flip the behaviour also. NB: the instructions VFMA and VFMS *are* decoded with op=3D0 for VFMA and op=3D1 for VFMS; the confusion probably arose because we assumed VFNMA and VFNMS to be the same way around.
