Re: attempt to use poisoned "CONST_COSTS"

2.      #define CONST_COSTS(RTX, CODE, OUTER_CODE)      \
                case CONST_INT:                         \
    			return target_const_costs (RTX, OUTER_CODE);  
\
                case CONST:                                     \
                        return 5;                                   \
                case LABEL_REF:                         \
                        return 1;                                   \
                case SYMBOL_REF:                                \
                        return ((TARGET_SMALL_MODEL)? 2: 3);        \
                case CONST_DOUBLE:                              \
                        return 10;
                        
        i dont know the corresponding macro in 3.4.6

It is now merged into RTX_COSTS.

You should look at a small back-end, e.g. pdp11, and see how to rewrite 
these macros into functions (target hooks).
