6289 calculation to account for the SVE save area. Only mark the

6295 and for it to act as a probe at SP. Account for the SVE callee
6296 save area in the dump information.
6297 (aarch64_expand_prologue): Update the frame diagram. Fold the
6298 SVE callee allocation into the initial allocation if stack clash
6299 protection is enabled. Use new variables to track the offset
6300 of the frame chain (and hard frame pointer) from the current
6301 stack pointer, and likewise the offset of the bottom of the
6302 register save area. Update calls to aarch64_save_callee_saves
6303 and aarch64_add_cfa_expression. Apply sve_callee_adjust before
6304 saving the FP&SIMD registers. Save the predicate registers.
6305 (aarch64_expand_epilogue): Take below_hard_fp_saved_regs_size
6306 into account when setting the stack pointer from the frame pointer,
6307 and when deciding whether we can inherit the initial adjustment
6308 amount from the prologue. Restore the predicate registers after
6309 the vector registers, then apply sve_callee_adjust, then restore
6310 the general registers.
