Peter Pettersson 3bd7a829db Some optimizations for the hardware divider (#1033) ... * Remove unnecessary wait in pico_divider. There is no need to wait if there is more than 8 cycles between setup and result readout. Dividend/divisor readout should be correct without delay. Update comment to reflect that. * Optimize hw_divider_save_state/hw_divider_restore_state. Doing multiple pushes to avoid stack usage is faster. The wait loop in hw_divider_save_state had an incorrect branch in the wait loop. This didn't matter since the wait wasn't necessary to begin with. * Remove pointless aligns in hardware_divider. The regular_func_with_section inserts a new section so if aligning is desired it should be placed in the macro after section start. * Save a few bytes in hardware_divider. Signed and unsigned code can use the same exit code. Branching to the common code is free since we need the 8 cycle delay anyway.		2022-10-16 17:40:22 -05:00
