 Not a problem:

 m68000-hp-hpux*)                # HP 9000 series 300
        if test x$gas = xyes
        then
                tm_file=m68k/hp310g.h
        else
                tm_file=m68k/hp310.h
        fi

both hp310.h and hp310g.h include hp320.h, which contains:

 #ifndef USE_GAS
 #define MOTOROLA                /* Use Motorola syntax rather than "MIT" */
 #define SGS                     /* Uses SGS assembler */
 #define SGS_CMP_ORDER           /* Takes cmp operands in reverse order */
 #define HPUX_ASM
 [...]

So we're either using GAS, supporting both syntaxes, or the SGS
assembler which is basically MOTOROLA + some tweaks.
