Yeah I’d say that modern OoO Arm implementations (A57, A72, ...) are worth trying to speculate into trapped VFP state. Lazy FPU is definitly a thing everywhere. My hunch says that chips affected by 4a could easily be fair game (4a is speculating reads into priviledged regs... I wonder if 4a would work on regs that are trapped, not inconceivable) |
