6299 tear-down strategies for the new layout, initializing the new
6300 sve_callee_adjust field. Add an additional layout for frames
6301 whose saved registers are all SVE registers.
6302 (aarch64_register_saved_on_entry): Cope with poly_int64 reg_offsets.
6303 (aarch64_return_address_signing_enabled): Likewise.
6304 (aarch64_push_regs, aarch64_pop_regs): Update calls to
6305 aarch64_reg_save_mode.
6306 (aarch64_adjust_sve_callee_save_base): New function.
6307 (aarch64_add_cfa_expression): Move earlier in file. Take the
6308 saved register as an rtx rather than a register number and use
6309 its mode for the MEM slot.
6310 (aarch64_save_callee_saves): Remove the mode argument and instead
6311 use aarch64_reg_save_mode to get the mode of each save slot.
6312 Add a hard_fp_valid_p parameter. Cope with poly_int64 register
6313 offsets. Allow GP offsets to be saved at a VL-based offset from
6314 the stack, handling this case using the frame pointer if available
6315 or a temporary register otherwise. Use ST1D to save Z8-Z15 for
6316 big-endian SVE functions; use normal moves for other SVE saves.
6317 Only mark the save as frame-related if aarch64_emit_cfi_for_reg_p
6318 returns true. Add explicit CFA notes when not storing via the
6319 stack pointer. Do not try to pair SVE saves.
6320 (aarch64_restore_callee_saves): Cope with poly_int64 register
6321 offsets. Use LD1D to restore Z8-Z15 for big-endian SVE functions;
6322 use normal moves for other SVE restores. Only add CFA restore notes
6323 if aarch64_emit_cfi_for_reg_p returns true. Do not try to pair
6325 (aarch64_get_separate_components): Always keep the first SVE save
6326 in the prologue if we need to use it as a stack probe. Don't allow
6327 Z8-Z15 saves and loads to be shrink-wrapped for big-endian targets.
6328 Likewise the spare predicate register that they need. Update the
6329 offset calculation to account for the SVE save area. Use the
6330 appropriate range check for SVE LDR and STR instructions.
6331 (aarch64_components_for_bb): Cope with poly_int64 reg_offsets.
6332 (aarch64_process_components): Likewise. Update the offset
6333 calculation to account for the SVE save area. Only mark the
6334 save as frame-related if aarch64_emit_cfi_for_reg_p returns true.
6335 Do not try to pair SVE saves.
6336 (aarch64_allocate_and_probe_stack_space): Cope with poly_int64
6337 reg_offsets. When handling the final allocation, expect the
6338 first SVE register save to be part of the initial allocation
6339 and for it to act as a probe at SP. Account for the SVE callee
6340 save area in the dump information.
6341 (aarch64_expand_prologue): Update the frame diagram. Fold the
6342 SVE callee allocation into the initial allocation if stack clash
6343 protection is enabled. Use new variables to track the offset
6344 of the frame chain (and hard frame pointer) from the current
6345 stack pointer, and likewise the offset of the bottom of the
6346 register save area. Update calls to aarch64_save_callee_saves
6347 and aarch64_add_cfa_expression. Apply sve_callee_adjust before
6348 saving the FP&SIMD registers. Save the predicate registers.
6349 (aarch64_expand_epilogue): Take below_hard_fp_saved_regs_size
6350 into account when setting the stack pointer from the frame pointer,
6351 and when deciding whether we can inherit the initial adjustment
6352 amount from the prologue. Restore the predicate registers after
6353 the vector registers, then apply sve_callee_adjust, then restore
6354 the general registers.
6355 (aarch64_secondary_reload): Don't use secondary SVE reloads
6357 (aapcs_vfp_sub_candidate): Assert that the type is not an SVE type.
6358 (aarch64_short_vector_p): Return false for SVE types.
6359 (aarch64_vfp_is_call_or_return_candidate): Initialize *is_ha
6360 at the start of the function. Return false for SVE types.
6361 (aarch64_asm_output_variant_pcs): Output .variant_pcs for SVE
6363 (TARGET_STRICT_ARGUMENT_NAMING): Redefine to request strict naming.
