6314 individual properties. Handle SVE predicates, vectors and tuples.
6315 Raise an error if they are passed to unprototyped functions.
6316 (aarch64_function_arg): If the silent_p flag is set, suppress the
6317 usual error about using float registers without TARGET_FLOAT.
6318 (aarch64_init_cumulative_args): Take a silent_p parameter and store
6319 it in the cumulative_args structure. Initialize aapcs_nprn and
6320 aapcs_nextnprn. If the silent_p flag is set, suppress the usual
6321 error about using float registers without TARGET_FLOAT.
6322 If the silent_p flag is not set, also raise an error about
6323 using SVE functions when SVE is disabled.
6324 (aarch64_function_arg_advance): Update the call to aarch64_layout_arg,
6325 and call it for SVE functions too. Update aapcs_nprn similarly
6326 to the other register counts.
6327 (aarch64_layout_frame): If a big-endian function needs to save
6328 and restore Z8-Z15, search for a spare predicate that it can use.
6329 Store SVE predicates at the bottom of the register save area,
6330 followed by SVE vectors, then followed by the normal slots.
6331 Keep pointing the hard frame pointer at the base of the normal slots,
6332 above the SVE vectors. Update the various frame creation and
6333 tear-down strategies for the new layout, initializing the new
6334 sve_callee_adjust field. Add an additional layout for frames
6335 whose saved registers are all SVE registers.
6336 (aarch64_register_saved_on_entry): Cope with poly_int64 reg_offsets.
6337 (aarch64_return_address_signing_enabled): Likewise.
6338 (aarch64_push_regs, aarch64_pop_regs): Update calls to
6339 aarch64_reg_save_mode.
6340 (aarch64_adjust_sve_callee_save_base): New function.
6341 (aarch64_add_cfa_expression): Move earlier in file. Take the
6342 saved register as an rtx rather than a register number and use
6343 its mode for the MEM slot.
6344 (aarch64_save_callee_saves): Remove the mode argument and instead
6345 use aarch64_reg_save_mode to get the mode of each save slot.
6346 Add a hard_fp_valid_p parameter. Cope with poly_int64 register
6347 offsets. Allow GP offsets to be saved at a VL-based offset from
6348 the stack, handling this case using the frame pointer if available
6349 or a temporary register otherwise. Use ST1D to save Z8-Z15 for
6350 big-endian SVE functions; use normal moves for other SVE saves.
6351 Only mark the save as frame-related if aarch64_emit_cfi_for_reg_p
6352 returns true. Add explicit CFA notes when not storing via the
6353 stack pointer. Do not try to pair SVE saves.
6354 (aarch64_restore_callee_saves): Cope with poly_int64 register
6355 offsets. Use LD1D to restore Z8-Z15 for big-endian SVE functions;
6356 use normal moves for other SVE restores. Only add CFA restore notes
6357 if aarch64_emit_cfi_for_reg_p returns true. Do not try to pair
6359 (aarch64_get_separate_components): Always keep the first SVE save
6360 in the prologue if we need to use it as a stack probe. Don't allow
6361 Z8-Z15 saves and loads to be shrink-wrapped for big-endian targets.
6362 Likewise the spare predicate register that they need. Update the
6363 offset calculation to account for the SVE save area. Use the
6364 appropriate range check for SVE LDR and STR instructions.
6365 (aarch64_components_for_bb): Cope with poly_int64 reg_offsets.
6366 (aarch64_process_components): Likewise. Update the offset
6367 calculation to account for the SVE save area. Only mark the
6368 save as frame-related if aarch64_emit_cfi_for_reg_p returns true.
6369 Do not try to pair SVE saves.
6370 (aarch64_allocate_and_probe_stack_space): Cope with poly_int64
6371 reg_offsets. When handling the final allocation, expect the
6372 first SVE register save to be part of the initial allocation
6373 and for it to act as a probe at SP. Account for the SVE callee
6374 save area in the dump information.
6375 (aarch64_expand_prologue): Update the frame diagram. Fold the
6376 SVE callee allocation into the initial allocation if stack clash
6377 protection is enabled. Use new variables to track the offset
6378 of the frame chain (and hard frame pointer) from the current
6379 stack pointer, and likewise the offset of the bottom of the
6380 register save area. Update calls to aarch64_save_callee_saves
6381 and aarch64_add_cfa_expression. Apply sve_callee_adjust before
6382 saving the FP&SIMD registers. Save the predicate registers.
6383 (aarch64_expand_epilogue): Take below_hard_fp_saved_regs_size
6384 into account when setting the stack pointer from the frame pointer,
6385 and when deciding whether we can inherit the initial adjustment
6386 amount from the prologue. Restore the predicate registers after
6387 the vector registers, then apply sve_callee_adjust, then restore
6388 the general registers.
6389 (aarch64_secondary_reload): Don't use secondary SVE reloads
6391 (aapcs_vfp_sub_candidate): Assert that the type is not an SVE type.
6392 (aarch64_short_vector_p): Return false for SVE types.
6393 (aarch64_vfp_is_call_or_return_candidate): Initialize *is_ha
6394 at the start of the function. Return false for SVE types.
6395 (aarch64_asm_output_variant_pcs): Output .variant_pcs for SVE
6397 (TARGET_STRICT_ARGUMENT_NAMING): Redefine to request strict naming.
