Under unshared FP registers mode the FP register bank is meant to be used by a single thread context. Therefore, there is no need for automatic stacking of the FP register bank at exception entries, or context switch, as the registers are not expected to be shared among multiple contexts. Under unshared FP registers mode we only need to clear the FPSCR register once, before jumping to main(). However, we initialize the FPSCR already at boot in case FP operations need to be performed during boot. Signed-off-by: Ioannis Glaropoulos <Ioannis.Glaropoulos@nordicsemi.no> |
