3177 big-endian SVE functions; use normal moves for other SVE saves.
3178 Only mark the save as frame-related if aarch64_emit_cfi_for_reg_p
3179 returns true. Add explicit CFA notes when not storing via the
3180 stack pointer. Do not try to pair SVE saves.
3181 (aarch64_restore_callee_saves): Cope with poly_int64 register
3182 offsets. Use LD1D to restore Z8-Z15 for big-endian SVE functions;
3183 use normal moves for other SVE restores. Only add CFA restore notes
3184 if aarch64_emit_cfi_for_reg_p returns true. Do not try to pair
3186 (aarch64_get_separate_components): Always keep the first SVE save
3187 in the prologue if we need to use it as a stack probe. Don't allow
3188 Z8-Z15 saves and loads to be shrink-wrapped for big-endian targets.
3189 Likewise the spare predicate register that they need. Update the
3190 offset calculation to account for the SVE save area. Use the
3191 appropriate range check for SVE LDR and STR instructions.
3192 (aarch64_components_for_bb): Cope with poly_int64 reg_offsets.
3193 (aarch64_process_components): Likewise. Update the offset
3194 calculation to account for the SVE save area. Only mark the

3196 Do not try to pair SVE saves.
3197 (aarch64_allocate_and_probe_stack_space): Cope with poly_int64
3198 reg_offsets. When handling the final allocation, expect the
3199 first SVE register save to be part of the initial allocation
3200 and for it to act as a probe at SP. Account for the SVE callee
3201 save area in the dump information.
3202 (aarch64_expand_prologue): Update the frame diagram. Fold the
3203 SVE callee allocation into the initial allocation if stack clash
3204 protection is enabled. Use new variables to track the offset
3205 of the frame chain (and hard frame pointer) from the current
3206 stack pointer, and likewise the offset of the bottom of the
3207 register save area. Update calls to aarch64_save_callee_saves
3208 and aarch64_add_cfa_expression. Apply sve_callee_adjust before
3209 saving the FP&SIMD registers. Save the predicate registers.
3210 (aarch64_expand_epilogue): Take below_hard_fp_saved_regs_size
3211 into account when setting the stack pointer from the frame pointer,
3212 and when deciding whether we can inherit the initial adjustment
3213 amount from the prologue. Restore the predicate registers after
3214 the vector registers, then apply sve_callee_adjust, then restore
3215 the general registers.
3216 (aarch64_secondary_reload): Don't use secondary SVE reloads
3218 (aapcs_vfp_sub_candidate): Assert that the type is not an SVE type.
3219 (aarch64_short_vector_p): Return false for SVE types.

3221 at the start of the function. Return false for SVE types.
