------- Comment #1 from rguenth at gcc dot gnu dot org  2009-11-08 11:31 -------
There's a typo here:

               asm( "pshufd   $0x55,%1,%&" : "=x"(A) : "g"(S) );

%& is not valid.

        PR target/41985
        * config/i386/i386.c (get_some_local_dynamic_name): Don't assert
        function contains at least one local dynamic name.
        (print_operand) <case '&'>: Instead output operand lossage diagnostics
        here if that happens.

        * gcc.target/i386/pr41985.c: New test.
