6308 (aarch64_function_arg): If the silent_p flag is set, suppress the
6309 usual error about using float registers without TARGET_FLOAT.
6310 (aarch64_init_cumulative_args): Take a silent_p parameter and store
6311 it in the cumulative_args structure. Initialize aapcs_nprn and
6312 aapcs_nextnprn. If the silent_p flag is set, suppress the usual
6313 error about using float registers without TARGET_FLOAT.
6314 If the silent_p flag is not set, also raise an error about
6315 using SVE functions when SVE is disabled.
6316 (aarch64_function_arg_advance): Update the call to aarch64_layout_arg,
6317 and call it for SVE functions too. Update aapcs_nprn similarly
6318 to the other register counts.
6319 (aarch64_layout_frame): If a big-endian function needs to save
6320 and restore Z8-Z15, search for a spare predicate that it can use.
6321 Store SVE predicates at the bottom of the register save area,
6322 followed by SVE vectors, then followed by the normal slots.
6323 Keep pointing the hard frame pointer at the base of the normal slots,
6324 above the SVE vectors. Update the various frame creation and
6325 tear-down strategies for the new layout, initializing the new
6326 sve_callee_adjust field. Add an additional layout for frames
6327 whose saved registers are all SVE registers.
6328 (aarch64_register_saved_on_entry): Cope with poly_int64 reg_offsets.
6329 (aarch64_return_address_signing_enabled): Likewise.
6330 (aarch64_push_regs, aarch64_pop_regs): Update calls to
6331 aarch64_reg_save_mode.
6332 (aarch64_adjust_sve_callee_save_base): New function.
6333 (aarch64_add_cfa_expression): Move earlier in file. Take the
6334 saved register as an rtx rather than a register number and use
6335 its mode for the MEM slot.
6336 (aarch64_save_callee_saves): Remove the mode argument and instead
6337 use aarch64_reg_save_mode to get the mode of each save slot.
6338 Add a hard_fp_valid_p parameter. Cope with poly_int64 register
6339 offsets. Allow GP offsets to be saved at a VL-based offset from
6340 the stack, handling this case using the frame pointer if available
6341 or a temporary register otherwise. Use ST1D to save Z8-Z15 for
6342 big-endian SVE functions; use normal moves for other SVE saves.
6343 Only mark the save as frame-related if aarch64_emit_cfi_for_reg_p
6344 returns true. Add explicit CFA notes when not storing via the
6345 stack pointer. Do not try to pair SVE saves.
6346 (aarch64_restore_callee_saves): Cope with poly_int64 register
6347 offsets. Use LD1D to restore Z8-Z15 for big-endian SVE functions;
6348 use normal moves for other SVE restores. Only add CFA restore notes
6349 if aarch64_emit_cfi_for_reg_p returns true. Do not try to pair
6351 (aarch64_get_separate_components): Always keep the first SVE save
6352 in the prologue if we need to use it as a stack probe. Don't allow
6353 Z8-Z15 saves and loads to be shrink-wrapped for big-endian targets.
6354 Likewise the spare predicate register that they need. Update the
6355 offset calculation to account for the SVE save area. Use the
6356 appropriate range check for SVE LDR and STR instructions.
6357 (aarch64_components_for_bb): Cope with poly_int64 reg_offsets.
6358 (aarch64_process_components): Likewise. Update the offset
6359 calculation to account for the SVE save area. Only mark the
6360 save as frame-related if aarch64_emit_cfi_for_reg_p returns true.
6361 Do not try to pair SVE saves.
6362 (aarch64_allocate_and_probe_stack_space): Cope with poly_int64
6363 reg_offsets. When handling the final allocation, expect the
6364 first SVE register save to be part of the initial allocation
6365 and for it to act as a probe at SP. Account for the SVE callee
6366 save area in the dump information.
6367 (aarch64_expand_prologue): Update the frame diagram. Fold the
6368 SVE callee allocation into the initial allocation if stack clash
6369 protection is enabled. Use new variables to track the offset
6370 of the frame chain (and hard frame pointer) from the current
6371 stack pointer, and likewise the offset of the bottom of the
6372 register save area. Update calls to aarch64_save_callee_saves
6373 and aarch64_add_cfa_expression. Apply sve_callee_adjust before
6374 saving the FP&SIMD registers. Save the predicate registers.
6375 (aarch64_expand_epilogue): Take below_hard_fp_saved_regs_size
6376 into account when setting the stack pointer from the frame pointer,
6377 and when deciding whether we can inherit the initial adjustment
6378 amount from the prologue. Restore the predicate registers after
6379 the vector registers, then apply sve_callee_adjust, then restore
6380 the general registers.
6381 (aarch64_secondary_reload): Don't use secondary SVE reloads
6383 (aapcs_vfp_sub_candidate): Assert that the type is not an SVE type.
6384 (aarch64_short_vector_p): Return false for SVE types.
6385 (aarch64_vfp_is_call_or_return_candidate): Initialize *is_ha
6386 at the start of the function. Return false for SVE types.
6387 (aarch64_asm_output_variant_pcs): Output .variant_pcs for SVE
6389 (TARGET_STRICT_ARGUMENT_NAMING): Redefine to request strict naming.
