[RFC v7 16/42] target/arm: split vfp state setting from tcg helpers |
Date: |
Fri, 12 Mar 2021 18:22:17 +0100 |
cpu-vfp.c: vfp_get_fpsr and vfp_set_fpsr are needed also for KVM,
so create a new cpu-vfp.c
tcg/cpu-vfp.c: vfp_get_fpscr_from_host and vv are TCG-only, so we
move the implementation to tcg/cpu-vfp.c
kvm/helper-stubs.c: vfp_get_fpscr_from_host and vv stubs for KVM.
