6865 and restore Z8-Z15, search for a spare predicate that it can use.
6866 Store SVE predicates at the bottom of the register save area,
6867 followed by SVE vectors, then followed by the normal slots.

6882 use aarch64_reg_save_mode to get the mode of each save slot.
6883 Add a hard_fp_valid_p parameter. Cope with poly_int64 register
6884 offsets. Allow GP offsets to be saved at a VL-based offset from
6885 the stack, handling this case using the frame pointer if available
6886 or a temporary register otherwise. Use ST1D to save Z8-Z15 for
6887 big-endian SVE functions; use normal moves for other SVE saves.
6888 Only mark the save as frame-related if aarch64_emit_cfi_for_reg_p

6890 stack pointer. Do not try to pair SVE saves.

6897 in the prologue if we need to use it as a stack probe. Don't allow
6898 Z8-Z15 saves and loads to be shrink-wrapped for big-endian targets.

6907 (aarch64_allocate_and_probe_stack_space): Cope with poly_int64
6908 reg_offsets. When handling the final allocation, expect the
6909 first SVE register save to be part of the initial allocation
6910 and for it to act as a probe at SP. Account for the SVE callee
6911 save area in the dump information.
6912 (aarch64_expand_prologue): Update the frame diagram. Fold the
6913 SVE callee allocation into the initial allocation if stack clash
6914 protection is enabled. Use new variables to track the offset
6915 of the frame chain (and hard frame pointer) from the current
6916 stack pointer, and likewise the offset of the bottom of the
6917 register save area. Update calls to aarch64_save_callee_saves
6918 and aarch64_add_cfa_expression. Apply sve_callee_adjust before
6919 saving the FP&SIMD registers. Save the predicate registers.
6920 (aarch64_expand_epilogue): Take below_hard_fp_saved_regs_size
6921 into account when setting the stack pointer from the frame pointer,
6922 and when deciding whether we can inherit the initial adjustment
6923 amount from the prologue. Restore the predicate registers after
6924 the vector registers, then apply sve_callee_adjust, then restore
6925 the general registers.
