6302 its mode for the MEM slot.
6303 (aarch64_save_callee_saves): Remove the mode argument and instead
6304 use aarch64_reg_save_mode to get the mode of each save slot.
6305 Add a hard_fp_valid_p parameter. Cope with poly_int64 register
6306 offsets. Allow GP offsets to be saved at a VL-based offset from
6307 the stack, handling this case using the frame pointer if available
6308 or a temporary register otherwise. Use ST1D to save Z8-Z15 for
6309 big-endian SVE functions; use normal moves for other SVE saves.
6310 Only mark the save as frame-related if aarch64_emit_cfi_for_reg_p
6311 returns true. Add explicit CFA notes when not storing via the
6312 stack pointer. Do not try to pair SVE saves.
6313 (aarch64_restore_callee_saves): Cope with poly_int64 register
6314 offsets. Use LD1D to restore Z8-Z15 for big-endian SVE functions;
6315 use normal moves for other SVE restores. Only add CFA restore notes
6316 if aarch64_emit_cfi_for_reg_p returns true. Do not try to pair
6318 (aarch64_get_separate_components): Always keep the first SVE save
6319 in the prologue if we need to use it as a stack probe. Don't allow
6320 Z8-Z15 saves and loads to be shrink-wrapped for big-endian targets.
6321 Likewise the spare predicate register that they need. Update the
6322 offset calculation to account for the SVE save area. Use the
6323 appropriate range check for SVE LDR and STR instructions.
6324 (aarch64_components_for_bb): Cope with poly_int64 reg_offsets.
6325 (aarch64_process_components): Likewise. Update the offset
6326 calculation to account for the SVE save area. Only mark the
6327 save as frame-related if aarch64_emit_cfi_for_reg_p returns true.
6328 Do not try to pair SVE saves.
6329 (aarch64_allocate_and_probe_stack_space): Cope with poly_int64
6330 reg_offsets. When handling the final allocation, expect the
6331 first SVE register save to be part of the initial allocation
6332 and for it to act as a probe at SP. Account for the SVE callee
6333 save area in the dump information.
6334 (aarch64_expand_prologue): Update the frame diagram. Fold the
6335 SVE callee allocation into the initial allocation if stack clash
6336 protection is enabled. Use new variables to track the offset
6337 of the frame chain (and hard frame pointer) from the current
6338 stack pointer, and likewise the offset of the bottom of the
6339 register save area. Update calls to aarch64_save_callee_saves
6340 and aarch64_add_cfa_expression. Apply sve_callee_adjust before
6341 saving the FP&SIMD registers. Save the predicate registers.
6342 (aarch64_expand_epilogue): Take below_hard_fp_saved_regs_size
6343 into account when setting the stack pointer from the frame pointer,
6344 and when deciding whether we can inherit the initial adjustment
6345 amount from the prologue. Restore the predicate registers after
6346 the vector registers, then apply sve_callee_adjust, then restore
6347 the general registers.
6348 (aarch64_secondary_reload): Don't use secondary SVE reloads
6350 (aapcs_vfp_sub_candidate): Assert that the type is not an SVE type.
6351 (aarch64_short_vector_p): Return false for SVE types.
6352 (aarch64_vfp_is_call_or_return_candidate): Initialize *is_ha
6353 at the start of the function. Return false for SVE types.
