Subject: Menu to select register union type?

Hello,

GDB is increasingly getting registers that have a union type vis:

>  #if 0
> + union __gdb_builtin_type_vec128 
>    {
> +    int128_t uint128;
> +    float v4_float[4];
> +    int32_t v4_int32[4];
> +    int16_t v8_int16[8];
> +    int8_t v16_int8[16];
>    };
>  #endif

Would it be possible to modify insight so that there was a menu that 
could be used to select just one of the union alternatives and display that?

At present insight appears to display all alternatives (which makes for 
very large register fields).

enjoy,
Andrew
