3601 * config/aarch64/aarch64.c (handle_aarch64_vector_pcs_attribute): New
3602 function. Reject aarch64_vector_pcs attributes on SVE functions.
3603 (aarch64_attribute_table): Use the above handler.

3609 descriptor for them.
3610 (aarch64_simd_decl_p): Delete.
3611 (aarch64_emit_cfi_for_reg_p): New function.
3612 (aarch64_reg_save_mode): Remove the fndecl argument and instead use
3613 crtl->abi to choose the mode for FP registers. Handle the SVE PCS.
3614 (aarch64_hard_regno_call_part_clobbered): Do not treat FP registers
3615 as partly clobbered for the SVE PCS.
3616 (aarch64_function_ok_for_sibcall): Check whether the two functions
3617 use the same ABI, rather than checking specifically for whether
3618 they're aarch64_vector_pcs functions.
3619 (aarch64_pass_by_reference): Raise an error for attempts to pass
3620 SVE arguments when SVE is disabled. Pass SVE arguments by reference
3621 if there are not enough free registers left, or if the argument is
3623 (aarch64_function_value): Handle SVE predicates, vectors and tuples.
3624 (aarch64_return_in_memory): Do not return SVE predicates, vectors and
3626 (aarch64_layout_arg): Take a function_arg_info rather than
3627 individual properties. Handle SVE predicates, vectors and tuples.
3628 Raise an error if they are passed to unprototyped functions.
3629 (aarch64_function_arg): If the silent_p flag is set, suppress the
3630 usual error about using float registers without TARGET_FLOAT.
3631 (aarch64_init_cumulative_args): Take a silent_p parameter and store
3632 it in the cumulative_args structure. Initialize aapcs_nprn and
3633 aapcs_nextnprn. If the silent_p flag is set, suppress the usual
3634 error about using float registers without TARGET_FLOAT.
3635 If the silent_p flag is not set, also raise an error about
3636 using SVE functions when SVE is disabled.
3637 (aarch64_function_arg_advance): Update the call to aarch64_layout_arg,
3638 and call it for SVE functions too. Update aapcs_nprn similarly
3639 to the other register counts.
3640 (aarch64_layout_frame): If a big-endian function needs to save
3641 and restore Z8-Z15, search for a spare predicate that it can use.
3642 Store SVE predicates at the bottom of the register save area,
3643 followed by SVE vectors, then followed by the normal slots.
3644 Keep pointing the hard frame pointer at the base of the normal slots,
3645 above the SVE vectors. Update the various frame creation and
3646 tear-down strategies for the new layout, initializing the new
3647 sve_callee_adjust field. Add an additional layout for frames
3648 whose saved registers are all SVE registers.
3649 (aarch64_register_saved_on_entry): Cope with poly_int64 reg_offsets.
3650 (aarch64_return_address_signing_enabled): Likewise.
3651 (aarch64_push_regs, aarch64_pop_regs): Update calls to
3652 aarch64_reg_save_mode.
3653 (aarch64_adjust_sve_callee_save_base): New function.
3654 (aarch64_add_cfa_expression): Move earlier in file. Take the
3655 saved register as an rtx rather than a register number and use
3656 its mode for the MEM slot.
3657 (aarch64_save_callee_saves): Remove the mode argument and instead
3658 use aarch64_reg_save_mode to get the mode of each save slot.
3659 Add a hard_fp_valid_p parameter. Cope with poly_int64 register
3660 offsets. Allow GP offsets to be saved at a VL-based offset from
3661 the stack, handling this case using the frame pointer if available
3662 or a temporary register otherwise. Use ST1D to save Z8-Z15 for
3663 big-endian SVE functions; use normal moves for other SVE saves.
3664 Only mark the save as frame-related if aarch64_emit_cfi_for_reg_p
3665 returns true. Add explicit CFA notes when not storing via the
3666 stack pointer. Do not try to pair SVE saves.
3667 (aarch64_restore_callee_saves): Cope with poly_int64 register
3668 offsets. Use LD1D to restore Z8-Z15 for big-endian SVE functions;
3669 use normal moves for other SVE restores. Only add CFA restore notes
3670 if aarch64_emit_cfi_for_reg_p returns true. Do not try to pair
3672 (aarch64_get_separate_components): Always keep the first SVE save
3673 in the prologue if we need to use it as a stack probe. Don't allow
3674 Z8-Z15 saves and loads to be shrink-wrapped for big-endian targets.
3675 Likewise the spare predicate register that they need. Update the
3676 offset calculation to account for the SVE save area. Use the
3677 appropriate range check for SVE LDR and STR instructions.
3678 (aarch64_components_for_bb): Cope with poly_int64 reg_offsets.
3679 (aarch64_process_components): Likewise. Update the offset
3680 calculation to account for the SVE save area. Only mark the
3681 save as frame-related if aarch64_emit_cfi_for_reg_p returns true.
3682 Do not try to pair SVE saves.
3683 (aarch64_allocate_and_probe_stack_space): Cope with poly_int64
3684 reg_offsets. When handling the final allocation, expect the
3685 first SVE register save to be part of the initial allocation
3686 and for it to act as a probe at SP. Account for the SVE callee
3687 save area in the dump information.
3688 (aarch64_expand_prologue): Update the frame diagram. Fold the
3689 SVE callee allocation into the initial allocation if stack clash
3690 protection is enabled. Use new variables to track the offset
3691 of the frame chain (and hard frame pointer) from the current
3692 stack pointer, and likewise the offset of the bottom of the
3693 register save area. Update calls to aarch64_save_callee_saves
3694 and aarch64_add_cfa_expression. Apply sve_callee_adjust before
3695 saving the FP&SIMD registers. Save the predicate registers.
3696 (aarch64_expand_epilogue): Take below_hard_fp_saved_regs_size
3697 into account when setting the stack pointer from the frame pointer,
3698 and when deciding whether we can inherit the initial adjustment
3699 amount from the prologue. Restore the predicate registers after
3700 the vector registers, then apply sve_callee_adjust, then restore
3701 the general registers.
3702 (aarch64_secondary_reload): Don't use secondary SVE reloads
3704 (aapcs_vfp_sub_candidate): Assert that the type is not an SVE type.
3705 (aarch64_short_vector_p): Return false for SVE types.
3706 (aarch64_vfp_is_call_or_return_candidate): Initialize *is_ha
3707 at the start of the function. Return false for SVE types.
3708 (aarch64_asm_output_variant_pcs): Output .variant_pcs for SVE
3710 (TARGET_STRICT_ARGUMENT_NAMING): Redefine to request strict naming.
