6848 If the silent_p flag is not set, also raise an error about
6849 using SVE functions when SVE is disabled.
6850 (aarch64_function_arg_advance): Update the call to aarch64_layout_arg,
6851 and call it for SVE functions too. Update aapcs_nprn similarly
6852 to the other register counts.

6854 and restore Z8-Z15, search for a spare predicate that it can use.
6855 Store SVE predicates at the bottom of the register save area,
6856 followed by SVE vectors, then followed by the normal slots.
6857 Keep pointing the hard frame pointer at the base of the normal slots,
6858 above the SVE vectors. Update the various frame creation and
6859 tear-down strategies for the new layout, initializing the new
6860 sve_callee_adjust field. Add an additional layout for frames
6861 whose saved registers are all SVE registers.

6869 its mode for the MEM slot.
6870 (aarch64_save_callee_saves): Remove the mode argument and instead
6871 use aarch64_reg_save_mode to get the mode of each save slot.
6872 Add a hard_fp_valid_p parameter. Cope with poly_int64 register
6873 offsets. Allow GP offsets to be saved at a VL-based offset from
6874 the stack, handling this case using the frame pointer if available
6875 or a temporary register otherwise. Use ST1D to save Z8-Z15 for
6876 big-endian SVE functions; use normal moves for other SVE saves.
6877 Only mark the save as frame-related if aarch64_emit_cfi_for_reg_p
6878 returns true. Add explicit CFA notes when not storing via the
6879 stack pointer. Do not try to pair SVE saves.
6880 (aarch64_restore_callee_saves): Cope with poly_int64 register
6881 offsets. Use LD1D to restore Z8-Z15 for big-endian SVE functions;
6882 use normal moves for other SVE restores. Only add CFA restore notes
6883 if aarch64_emit_cfi_for_reg_p returns true. Do not try to pair
6885 (aarch64_get_separate_components): Always keep the first SVE save
6886 in the prologue if we need to use it as a stack probe. Don't allow
6887 Z8-Z15 saves and loads to be shrink-wrapped for big-endian targets.
6888 Likewise the spare predicate register that they need. Update the
6889 offset calculation to account for the SVE save area. Use the
6890 appropriate range check for SVE LDR and STR instructions.

6892 (aarch64_process_components): Likewise. Update the offset
6893 calculation to account for the SVE save area. Only mark the

6895 Do not try to pair SVE saves.
6896 (aarch64_allocate_and_probe_stack_space): Cope with poly_int64
6897 reg_offsets. When handling the final allocation, expect the
6898 first SVE register save to be part of the initial allocation
6899 and for it to act as a probe at SP. Account for the SVE callee
6900 save area in the dump information.
6901 (aarch64_expand_prologue): Update the frame diagram. Fold the
6902 SVE callee allocation into the initial allocation if stack clash
6903 protection is enabled. Use new variables to track the offset
6904 of the frame chain (and hard frame pointer) from the current
6905 stack pointer, and likewise the offset of the bottom of the
6906 register save area. Update calls to aarch64_save_callee_saves
6907 and aarch64_add_cfa_expression. Apply sve_callee_adjust before
6908 saving the FP&SIMD registers. Save the predicate registers.
6909 (aarch64_expand_epilogue): Take below_hard_fp_saved_regs_size
6910 into account when setting the stack pointer from the frame pointer,
6911 and when deciding whether we can inherit the initial adjustment
6912 amount from the prologue. Restore the predicate registers after
6913 the vector registers, then apply sve_callee_adjust, then restore
6914 the general registers.
6915 (aarch64_secondary_reload): Don't use secondary SVE reloads
6917 (aapcs_vfp_sub_candidate): Assert that the type is not an SVE type.
