If the exception bit is set we need to save and restore the FPINST register, and if the fp2v bit is also set we need to save and restore FPINST2. * Move saving and restoring the floating point control registers to C. * Clear the fpexc exception and fp2v flags on a floating-point exception. * Signal a SIGFPE if the fpexc exception flag is set on an undefined instruction. This is how the ARM core signals to software there is a floating-point exception. |
