6850 and restore Z8-Z15, search for a spare predicate that it can use.
6851 Store SVE predicates at the bottom of the register save area,
6852 followed by SVE vectors, then followed by the normal slots.
6853 Keep pointing the hard frame pointer at the base of the normal slots,
6854 above the SVE vectors. Update the various frame creation and
6855 tear-down strategies for the new layout, initializing the new

6867 use aarch64_reg_save_mode to get the mode of each save slot.
6868 Add a hard_fp_valid_p parameter. Cope with poly_int64 register
6869 offsets. Allow GP offsets to be saved at a VL-based offset from
6870 the stack, handling this case using the frame pointer if available
6871 or a temporary register otherwise. Use ST1D to save Z8-Z15 for
6872 big-endian SVE functions; use normal moves for other SVE saves.
6873 Only mark the save as frame-related if aarch64_emit_cfi_for_reg_p
6874 returns true. Add explicit CFA notes when not storing via the
6875 stack pointer. Do not try to pair SVE saves.

6877 offsets. Use LD1D to restore Z8-Z15 for big-endian SVE functions;

6881 (aarch64_get_separate_components): Always keep the first SVE save
6882 in the prologue if we need to use it as a stack probe. Don't allow
6883 Z8-Z15 saves and loads to be shrink-wrapped for big-endian targets.
6884 Likewise the spare predicate register that they need. Update the
6885 offset calculation to account for the SVE save area. Use the
6886 appropriate range check for SVE LDR and STR instructions.

6892 (aarch64_allocate_and_probe_stack_space): Cope with poly_int64
6893 reg_offsets. When handling the final allocation, expect the
6894 first SVE register save to be part of the initial allocation
6895 and for it to act as a probe at SP. Account for the SVE callee
6896 save area in the dump information.
6897 (aarch64_expand_prologue): Update the frame diagram. Fold the
6898 SVE callee allocation into the initial allocation if stack clash
6899 protection is enabled. Use new variables to track the offset
6900 of the frame chain (and hard frame pointer) from the current
6901 stack pointer, and likewise the offset of the bottom of the
6902 register save area. Update calls to aarch64_save_callee_saves
6903 and aarch64_add_cfa_expression. Apply sve_callee_adjust before
6904 saving the FP&SIMD registers. Save the predicate registers.
6905 (aarch64_expand_epilogue): Take below_hard_fp_saved_regs_size
6906 into account when setting the stack pointer from the frame pointer,
6907 and when deciding whether we can inherit the initial adjustment
6908 amount from the prologue. Restore the predicate registers after
6909 the vector registers, then apply sve_callee_adjust, then restore
6910 the general registers.
