expr.c (force_operand): Ignore flag_pic for detecting pic address loads.
* expr.c (force_operand): Ignore flag_pic for detecting pic
address loads.
* regclass.c (init_reg_sets_1): Test fixed_regs not flag_pic
for determining if PIC_OFFSET_TABLE_REGNUM is call-clobbered.
* resource.c (mark_target_live_regs): Use regs_invalidated_by_call
instead of open-coded loop.
* doc/tm.texi (PIC_OFFSET_TABLE_REGNUM): Clarify that it must
be fixed when in use.
