    * calls.c (emit_library_call_value): When pushing arguments use
    stack_pointer_rtx rather than virtual_outgoing_args_rtx in
    CALL_INSN_FUNCTION_USAGE.  Only emit one of use of the magic
    stack pointer reference into CALL_INSN_FUNCTION_USAGE.

    PR rtl-optimization/52773
    * gcc.c-torture/compile/pr52773.c: New test.
