7313 and restore Z8-Z15, search for a spare predicate that it can use.
7314 Store SVE predicates at the bottom of the register save area,
7315 followed by SVE vectors, then followed by the normal slots.
7316 Keep pointing the hard frame pointer at the base of the normal slots,
7317 above the SVE vectors. Update the various frame creation and
7318 tear-down strategies for the new layout, initializing the new
7319 sve_callee_adjust field. Add an additional layout for frames

7330 use aarch64_reg_save_mode to get the mode of each save slot.
7331 Add a hard_fp_valid_p parameter. Cope with poly_int64 register
7332 offsets. Allow GP offsets to be saved at a VL-based offset from
7333 the stack, handling this case using the frame pointer if available
7334 or a temporary register otherwise. Use ST1D to save Z8-Z15 for
7335 big-endian SVE functions; use normal moves for other SVE saves.
7336 Only mark the save as frame-related if aarch64_emit_cfi_for_reg_p
7337 returns true. Add explicit CFA notes when not storing via the
7338 stack pointer. Do not try to pair SVE saves.
7339 (aarch64_restore_callee_saves): Cope with poly_int64 register
7340 offsets. Use LD1D to restore Z8-Z15 for big-endian SVE functions;

7342 if aarch64_emit_cfi_for_reg_p returns true. Do not try to pair
7344 (aarch64_get_separate_components): Always keep the first SVE save
7345 in the prologue if we need to use it as a stack probe. Don't allow
7346 Z8-Z15 saves and loads to be shrink-wrapped for big-endian targets.
7347 Likewise the spare predicate register that they need. Update the
7348 offset calculation to account for the SVE save area. Use the
7349 appropriate range check for SVE LDR and STR instructions.

7355 (aarch64_allocate_and_probe_stack_space): Cope with poly_int64
7356 reg_offsets. When handling the final allocation, expect the
7357 first SVE register save to be part of the initial allocation
7358 and for it to act as a probe at SP. Account for the SVE callee
7359 save area in the dump information.
7360 (aarch64_expand_prologue): Update the frame diagram. Fold the
7361 SVE callee allocation into the initial allocation if stack clash
7362 protection is enabled. Use new variables to track the offset
7363 of the frame chain (and hard frame pointer) from the current
7364 stack pointer, and likewise the offset of the bottom of the
7365 register save area. Update calls to aarch64_save_callee_saves
7366 and aarch64_add_cfa_expression. Apply sve_callee_adjust before
7367 saving the FP&SIMD registers. Save the predicate registers.
7368 (aarch64_expand_epilogue): Take below_hard_fp_saved_regs_size
7369 into account when setting the stack pointer from the frame pointer,
7370 and when deciding whether we can inherit the initial adjustment
7371 amount from the prologue. Restore the predicate registers after
7372 the vector registers, then apply sve_callee_adjust, then restore
7373 the general registers.
