4New table:
5
6    sql = """create table if not exists callgraph (
7                id integer primary key,
8                func_id integer not null references functions(id) on delete cascade,
9                address text not null,
10                type text not null)"""
11    cur.execute(sql)
12
13In this table I insert all the callers and callees:
14
15    # Save the callers and callees of the function
16    callers, callees = props[len(props)-4:len(props)-2]
17    sql = "insert into callgraph (func_id, address, type) values (?, ?, ?)"
18    for caller in callers:
19      cur.execute(sql, (func_id, caller, 'caller'))
20    
21    for callee in callees:
22      cur.execute(sql, (func_id, callee, 'callee'))
23
24New field:
25
26In the table "functions" I have added a new field called:
27
28    assembly_addrs text
29
30In this field I insert a JSON list of all the addresses (sorted starting always from the entry point of the function). This list is used to match one-to-one assembly instructions from the origin database to the diffing database.
