Functions
uint32_t	pspfpu_get_fcr31 (void)
	Get the current value of the control/status register.
void	pspfpu_set_fcr31 (uint32_t var)
	Set the current value of the control/status register.
void	pspfpu_set_roundmode (enum FpuRoundMode mode)
	Set the current round mode.
enum FpuRoundMode	pspfpu_get_roundmode (void)
	Get the current round mode.
uint32_t	pspfpu_get_flags (void)
	Get the exception flags (set when an exception occurs but the actual exception bit is not enabled)
void	pspfpu_clear_flags (uint32_t clear)
	Clear the flags bits.
uint32_t	pspfpu_get_enable (void)
	Get the exception enable flags.
void	pspfpu_set_enable (uint32_t enable)
	Set the enable flags bits.
uint32_t	pspfpu_get_cause (void)
	Get the cause bits (only useful if you installed your own exception handler)
void	pspfpu_clear_cause (uint32_t clear)
	Clear the cause bits.
uint32_t	pspfpu_get_fs (void)
	Get the current value of the FS bit (if FS is 0 then an exception occurs with denormalized values, if 1 then they are rewritten as 0.

	Set the FS bit.
uint32_t	pspfpu_get_condbits (void)
	Get the condition flags (8 bits)
void	pspfpu_clear_condbits (uint32_t clear)
	Clear the condition bits.
