Re: dereferencing pointers from frysk.value

[Andrew Cagney <cagney at redhat dot com>]

So at present a "pointer" value is seen as a pair:
   type: pointer->char
   location: byte-buffer with size==sizeof(void*) and 
contents=="pointer value"
and there's nothing for the "pointer" to point into?

It sounds like the Type.toPrint() method should be parameterised with 
not just the ByteBuffer containing the value, but also the address space 
or segment[s] to which that value could refer.   As an aside, the 
toPrint method should probably also be parameterized with a base-type 
formatter so that <<print astruct -format x>> gives <<{ 0x123, 0x456 }>>

with these, PrintValue is reduced to:

   BaseTypeWriter baseTypeWriter = select writer based on -format
   Value result = cli.parseValue(expression);
   result.toPrint(outputWriter, task.getMemory(), baseTypeWriter)
