3261 as partly clobbered for the SVE PCS.
3262 (aarch64_function_ok_for_sibcall): Check whether the two functions
3263 use the same ABI, rather than checking specifically for whether
3264 they're aarch64_vector_pcs functions.
3265 (aarch64_pass_by_reference): Raise an error for attempts to pass
3266 SVE arguments when SVE is disabled. Pass SVE arguments by reference
3267 if there are not enough free registers left, or if the argument is
3269 (aarch64_function_value): Handle SVE predicates, vectors and tuples.

3273 individual properties. Handle SVE predicates, vectors and tuples.
3274 Raise an error if they are passed to unprototyped functions.
3275 (aarch64_function_arg): If the silent_p flag is set, suppress the
3276 usual error about using float registers without TARGET_FLOAT.
3277 (aarch64_init_cumulative_args): Take a silent_p parameter and store
3278 it in the cumulative_args structure. Initialize aapcs_nprn and
3279 aapcs_nextnprn. If the silent_p flag is set, suppress the usual
3280 error about using float registers without TARGET_FLOAT.
3281 If the silent_p flag is not set, also raise an error about
3282 using SVE functions when SVE is disabled.
3283 (aarch64_function_arg_advance): Update the call to aarch64_layout_arg,
3284 and call it for SVE functions too. Update aapcs_nprn similarly
3285 to the other register counts.
3286 (aarch64_layout_frame): If a big-endian function needs to save
3287 and restore Z8-Z15, search for a spare predicate that it can use.
3288 Store SVE predicates at the bottom of the register save area,
3289 followed by SVE vectors, then followed by the normal slots.
3290 Keep pointing the hard frame pointer at the base of the normal slots,
3291 above the SVE vectors. Update the various frame creation and
3292 tear-down strategies for the new layout, initializing the new
3293 sve_callee_adjust field. Add an additional layout for frames
3294 whose saved registers are all SVE registers.
3295 (aarch64_register_saved_on_entry): Cope with poly_int64 reg_offsets.
3296 (aarch64_return_address_signing_enabled): Likewise.

3299 (aarch64_adjust_sve_callee_save_base): New function.
3300 (aarch64_add_cfa_expression): Move earlier in file. Take the
3301 saved register as an rtx rather than a register number and use
3302 its mode for the MEM slot.
3303 (aarch64_save_callee_saves): Remove the mode argument and instead
3304 use aarch64_reg_save_mode to get the mode of each save slot.
3305 Add a hard_fp_valid_p parameter. Cope with poly_int64 register
3306 offsets. Allow GP offsets to be saved at a VL-based offset from
3307 the stack, handling this case using the frame pointer if available
3308 or a temporary register otherwise. Use ST1D to save Z8-Z15 for
3309 big-endian SVE functions; use normal moves for other SVE saves.
3310 Only mark the save as frame-related if aarch64_emit_cfi_for_reg_p
3311 returns true. Add explicit CFA notes when not storing via the
3312 stack pointer. Do not try to pair SVE saves.
3313 (aarch64_restore_callee_saves): Cope with poly_int64 register
3314 offsets. Use LD1D to restore Z8-Z15 for big-endian SVE functions;
3315 use normal moves for other SVE restores. Only add CFA restore notes
3316 if aarch64_emit_cfi_for_reg_p returns true. Do not try to pair
3318 (aarch64_get_separate_components): Always keep the first SVE save
3319 in the prologue if we need to use it as a stack probe. Don't allow
3320 Z8-Z15 saves and loads to be shrink-wrapped for big-endian targets.
3321 Likewise the spare predicate register that they need. Update the
3322 offset calculation to account for the SVE save area. Use the
3323 appropriate range check for SVE LDR and STR instructions.
3324 (aarch64_components_for_bb): Cope with poly_int64 reg_offsets.
3325 (aarch64_process_components): Likewise. Update the offset
3326 calculation to account for the SVE save area. Only mark the
3327 save as frame-related if aarch64_emit_cfi_for_reg_p returns true.
3328 Do not try to pair SVE saves.
3329 (aarch64_allocate_and_probe_stack_space): Cope with poly_int64
3330 reg_offsets. When handling the final allocation, expect the
3331 first SVE register save to be part of the initial allocation
3332 and for it to act as a probe at SP. Account for the SVE callee
3333 save area in the dump information.
3334 (aarch64_expand_prologue): Update the frame diagram. Fold the
3335 SVE callee allocation into the initial allocation if stack clash
3336 protection is enabled. Use new variables to track the offset
3337 of the frame chain (and hard frame pointer) from the current
3338 stack pointer, and likewise the offset of the bottom of the
3339 register save area. Update calls to aarch64_save_callee_saves
3340 and aarch64_add_cfa_expression. Apply sve_callee_adjust before
3341 saving the FP&SIMD registers. Save the predicate registers.
3342 (aarch64_expand_epilogue): Take below_hard_fp_saved_regs_size
3343 into account when setting the stack pointer from the frame pointer,
3344 and when deciding whether we can inherit the initial adjustment
3345 amount from the prologue. Restore the predicate registers after
3346 the vector registers, then apply sve_callee_adjust, then restore
3347 the general registers.
3348 (aarch64_secondary_reload): Don't use secondary SVE reloads
3350 (aapcs_vfp_sub_candidate): Assert that the type is not an SVE type.
3351 (aarch64_short_vector_p): Return false for SVE types.
3352 (aarch64_vfp_is_call_or_return_candidate): Initialize *is_ha
3353 at the start of the function. Return false for SVE types.
