target-mips: Add missing calls to synchronise SoftFloat status
Add missing calls to synchronise the SoftFloat status with the CP1.FSCR: + for the rounding and flush-to-zero modes upon processor reset, + for the flush-to-zero mode on FSCR updates through the GDB stub. Refactor code accordingly and remove the redundant RESTORE_ROUNDING_MODE macro. Signed-off-by: Thomas Schwinge <thomas@codesourcery.com> Signed-off-by: Maciej W. Rozycki <macro@codesourcery.com> Reviewed-by: Leon Alrae <leon.alrae@imgtec.com> Signed-off-by: Leon Alrae <leon.alrae@imgtec.com>
