pa.c (compute_frame_size): Take an fregs_live parameter instead of setting the static variable save_fregs.
* pa.c (compute_frame_size): Take an fregs_live parameter instead
of setting the static variable save_fregs.
(output_function_prologue): Initialize save_fregs to 0 and pass to
compute_frame_size.
