Can you explain more what you mean?
In this patch kvm/helper-stubs.c is updated to include two stubs:
uint32_t vfp_get_fpscr_from_host(CPUARMState *env)
{
return 0;
}
void vfp_set_fpscr_to_host(CPUARMState *env, uint32_t val)
{
}
The corresponding tcg code instead is in tcg/arm/cpu-vtp.c.
For the non-stub code that comprises
vfp_get_fpscr
vfp_set_fpscr
the code is moved to target/arm/cpu-vfp.c,
to be shared by tcg and kvm.
Thanks,
C
