At some point you have to read and edit the disassembly by hand to fix
up these offsets.  There just isn't enough information in the raw object
code to convert it back to the original program.

For example, these two C code fragments likely generate the same code. 
A disassembler/decompiler won't be able to know which way the programmer
originally coded it.

{
struct {int a; int b;} foo, bar;
foo.a = 1; foo.b = 2;
bar = foo;
}

{
int fooa, foob, bara, barb;
fooa = 1; foob = 2;
bara = fooa; barb = foob;
}
