6358 (aarch64_emit_cfi_for_reg_p): New function.
6359 (aarch64_reg_save_mode): Remove the fndecl argument and instead use
6360 crtl->abi to choose the mode for FP registers. Handle the SVE PCS.
6361 (aarch64_hard_regno_call_part_clobbered): Do not treat FP registers
6362 as partly clobbered for the SVE PCS.
6363 (aarch64_function_ok_for_sibcall): Check whether the two functions
6364 use the same ABI, rather than checking specifically for whether
6365 they're aarch64_vector_pcs functions.
6366 (aarch64_pass_by_reference): Raise an error for attempts to pass
6367 SVE arguments when SVE is disabled. Pass SVE arguments by reference
6368 if there are not enough free registers left, or if the argument is
6370 (aarch64_function_value): Handle SVE predicates, vectors and tuples.
6371 (aarch64_return_in_memory): Do not return SVE predicates, vectors and
6373 (aarch64_layout_arg): Take a function_arg_info rather than
6374 individual properties. Handle SVE predicates, vectors and tuples.
6375 Raise an error if they are passed to unprototyped functions.
6376 (aarch64_function_arg): If the silent_p flag is set, suppress the
6377 usual error about using float registers without TARGET_FLOAT.
6378 (aarch64_init_cumulative_args): Take a silent_p parameter and store
6379 it in the cumulative_args structure. Initialize aapcs_nprn and
6380 aapcs_nextnprn. If the silent_p flag is set, suppress the usual
6381 error about using float registers without TARGET_FLOAT.
6382 If the silent_p flag is not set, also raise an error about
6383 using SVE functions when SVE is disabled.
6384 (aarch64_function_arg_advance): Update the call to aarch64_layout_arg,
6385 and call it for SVE functions too. Update aapcs_nprn similarly
6386 to the other register counts.
6387 (aarch64_layout_frame): If a big-endian function needs to save
6388 and restore Z8-Z15, search for a spare predicate that it can use.
6389 Store SVE predicates at the bottom of the register save area,
6390 followed by SVE vectors, then followed by the normal slots.
6391 Keep pointing the hard frame pointer at the base of the normal slots,
6392 above the SVE vectors. Update the various frame creation and
6393 tear-down strategies for the new layout, initializing the new
6394 sve_callee_adjust field. Add an additional layout for frames
6395 whose saved registers are all SVE registers.
6396 (aarch64_register_saved_on_entry): Cope with poly_int64 reg_offsets.
6397 (aarch64_return_address_signing_enabled): Likewise.
6398 (aarch64_push_regs, aarch64_pop_regs): Update calls to
6399 aarch64_reg_save_mode.
6400 (aarch64_adjust_sve_callee_save_base): New function.
6401 (aarch64_add_cfa_expression): Move earlier in file. Take the
6402 saved register as an rtx rather than a register number and use
6403 its mode for the MEM slot.
6404 (aarch64_save_callee_saves): Remove the mode argument and instead
6405 use aarch64_reg_save_mode to get the mode of each save slot.
6406 Add a hard_fp_valid_p parameter. Cope with poly_int64 register
6407 offsets. Allow GP offsets to be saved at a VL-based offset from
6408 the stack, handling this case using the frame pointer if available
6409 or a temporary register otherwise. Use ST1D to save Z8-Z15 for
6410 big-endian SVE functions; use normal moves for other SVE saves.
6411 Only mark the save as frame-related if aarch64_emit_cfi_for_reg_p
6412 returns true. Add explicit CFA notes when not storing via the
6413 stack pointer. Do not try to pair SVE saves.
6414 (aarch64_restore_callee_saves): Cope with poly_int64 register
6415 offsets. Use LD1D to restore Z8-Z15 for big-endian SVE functions;
6416 use normal moves for other SVE restores. Only add CFA restore notes
6417 if aarch64_emit_cfi_for_reg_p returns true. Do not try to pair
6419 (aarch64_get_separate_components): Always keep the first SVE save
6420 in the prologue if we need to use it as a stack probe. Don't allow
6421 Z8-Z15 saves and loads to be shrink-wrapped for big-endian targets.
6422 Likewise the spare predicate register that they need. Update the
6423 offset calculation to account for the SVE save area. Use the
6424 appropriate range check for SVE LDR and STR instructions.
6425 (aarch64_components_for_bb): Cope with poly_int64 reg_offsets.
6426 (aarch64_process_components): Likewise. Update the offset
6427 calculation to account for the SVE save area. Only mark the
6428 save as frame-related if aarch64_emit_cfi_for_reg_p returns true.
6429 Do not try to pair SVE saves.
6430 (aarch64_allocate_and_probe_stack_space): Cope with poly_int64
6431 reg_offsets. When handling the final allocation, expect the
6432 first SVE register save to be part of the initial allocation
6433 and for it to act as a probe at SP. Account for the SVE callee
6434 save area in the dump information.
6435 (aarch64_expand_prologue): Update the frame diagram. Fold the
6436 SVE callee allocation into the initial allocation if stack clash
6437 protection is enabled. Use new variables to track the offset
6438 of the frame chain (and hard frame pointer) from the current
6439 stack pointer, and likewise the offset of the bottom of the
6440 register save area. Update calls to aarch64_save_callee_saves
6441 and aarch64_add_cfa_expression. Apply sve_callee_adjust before
6442 saving the FP&SIMD registers. Save the predicate registers.
6443 (aarch64_expand_epilogue): Take below_hard_fp_saved_regs_size
6444 into account when setting the stack pointer from the frame pointer,
6445 and when deciding whether we can inherit the initial adjustment
6446 amount from the prologue. Restore the predicate registers after
6447 the vector registers, then apply sve_callee_adjust, then restore
6448 the general registers.
6449 (aarch64_secondary_reload): Don't use secondary SVE reloads
6451 (aapcs_vfp_sub_candidate): Assert that the type is not an SVE type.
6452 (aarch64_short_vector_p): Return false for SVE types.
6453 (aarch64_vfp_is_call_or_return_candidate): Initialize *is_ha
6454 at the start of the function. Return false for SVE types.
