* config/xtensa/xtensa-protos.h (xtensa_copy_incoming_a7): Update.
(init_cumulative_args): Likewise.
(a7_overlap_mentioned_p): Delete prototype.
* config/xtensa/xtensa.c (struct machine_function): Replace
incoming_a7_copied field with need_a7_copy and vararg_a7 flags.
Add set_frame_ptr_insn field.
(xtensa_emit_move_sequence): Update call to xtensa_copy_incoming_a7.
(xtensa_copy_incoming_a7): Rewrite to check need_a7_copy flag and check
if the operand is an argument in a7. If so, copy a7 to a new pseudo
at the function entry and replace the operand with the pseudo.
(init_cumulative_args): Remove unused arguments. Add new "incoming"
argument and record this flag in CUMULATIVE_ARGS.
(function_arg): Remove result_mode and special-case code to handle
arguments in a7. Instead, set need_a7_copy flag when there is an
incoming argument in a7.
(xtensa_expand_prologue): Remove code to search for set_frame_ptr insn
and use the value recorded in cfun->machine->set_frame_ptr_insn.
(xtensa_builtin_saveregs): Check for negative gp_left value. Set
need_a7_copy and vararg_a7 flags. Use move_block_from_reg instead of
special-case code.
(a7_overlap_mentioned_p): Delete.
* config/xtensa/xtensa.h (CUMULATIVE_ARGS): Add "incoming" flag.
(INIT_CUMULATIVE_ARGS, INIT_CUMULATIVE_INCOMING_ARGS): Remove useless
arguments to init_cumulative_args and pass "incoming" flag instead.
(BLOCK_REG_PADDING): Delete.
* config/xtensa/xtensa.md (movdi, movsf, movdf): Remove unnecessary
checks for reload_in_progress and reload_completed. Update calls to
xtensa_copy_incoming_a7.
(ashlsi3): Rename existing insn to ashlsi3_internal. Add expander
to call xtensa_copy_incoming_a7.
