* ppc-tdep.h (struct gdbarch_tdep): Add new member ``lr_frame_offset''.
* rs6000-tdep.c (rs6000_frame_saved_pc): Use ``lr_frame_offset''
from tdep struct instead of DEFAULT_LR_SAVE.
(rs6000_gdbarch_init): Initialize ``lr_frame_offset''.
* config/powerpc/tm-ppc-eabi.h (DEFAULT_LR_SAVE): Delete.
* config/rs6000/tm-rs6000.h (DEFAULT_LR_SAVE): Delete.
2002-04-12 Michael Snyder <msnyder@redhat.com>
* source.c: White space fix-up.
