2843 If the silent_p flag is not set, also raise an error about
2844 using SVE functions when SVE is disabled.
2845 (aarch64_function_arg_advance): Update the call to aarch64_layout_arg,
2846 and call it for SVE functions too. Update aapcs_nprn similarly

2849 and restore Z8-Z15, search for a spare predicate that it can use.
2850 Store SVE predicates at the bottom of the register save area,
2851 followed by SVE vectors, then followed by the normal slots.
2852 Keep pointing the hard frame pointer at the base of the normal slots,
2853 above the SVE vectors. Update the various frame creation and
2854 tear-down strategies for the new layout, initializing the new
2855 sve_callee_adjust field. Add an additional layout for frames
2856 whose saved registers are all SVE registers.

2864 its mode for the MEM slot.
2865 (aarch64_save_callee_saves): Remove the mode argument and instead
2866 use aarch64_reg_save_mode to get the mode of each save slot.
2867 Add a hard_fp_valid_p parameter. Cope with poly_int64 register
2868 offsets. Allow GP offsets to be saved at a VL-based offset from
2869 the stack, handling this case using the frame pointer if available
2870 or a temporary register otherwise. Use ST1D to save Z8-Z15 for
2871 big-endian SVE functions; use normal moves for other SVE saves.
2872 Only mark the save as frame-related if aarch64_emit_cfi_for_reg_p
2873 returns true. Add explicit CFA notes when not storing via the
2874 stack pointer. Do not try to pair SVE saves.
2875 (aarch64_restore_callee_saves): Cope with poly_int64 register
2876 offsets. Use LD1D to restore Z8-Z15 for big-endian SVE functions;
2877 use normal moves for other SVE restores. Only add CFA restore notes
2878 if aarch64_emit_cfi_for_reg_p returns true. Do not try to pair
2880 (aarch64_get_separate_components): Always keep the first SVE save
2881 in the prologue if we need to use it as a stack probe. Don't allow
2882 Z8-Z15 saves and loads to be shrink-wrapped for big-endian targets.
2883 Likewise the spare predicate register that they need. Update the
2884 offset calculation to account for the SVE save area. Use the
2885 appropriate range check for SVE LDR and STR instructions.

2887 (aarch64_process_components): Likewise. Update the offset

2890 Do not try to pair SVE saves.
2891 (aarch64_allocate_and_probe_stack_space): Cope with poly_int64
2892 reg_offsets. When handling the final allocation, expect the
2893 first SVE register save to be part of the initial allocation
2894 and for it to act as a probe at SP. Account for the SVE callee
2895 save area in the dump information.
2896 (aarch64_expand_prologue): Update the frame diagram. Fold the
2897 SVE callee allocation into the initial allocation if stack clash
2898 protection is enabled. Use new variables to track the offset
2899 of the frame chain (and hard frame pointer) from the current
2900 stack pointer, and likewise the offset of the bottom of the
2901 register save area. Update calls to aarch64_save_callee_saves
2902 and aarch64_add_cfa_expression. Apply sve_callee_adjust before
2903 saving the FP&SIMD registers. Save the predicate registers.
2904 (aarch64_expand_epilogue): Take below_hard_fp_saved_regs_size
2905 into account when setting the stack pointer from the frame pointer,
2906 and when deciding whether we can inherit the initial adjustment
2907 amount from the prologue. Restore the predicate registers after
2908 the vector registers, then apply sve_callee_adjust, then restore
2909 the general registers.
