db means “define byte”, i.e. a reservation of 1 byte of memory,
dw means “define word” (2 bytes of memory),
dd means “define double-word” (4 bytes of memory).
in graph view, edges represent branches between nodes. blue for unconditional, green for true, and red for false branch taken
can group nodes
creating structs with padding, say you see an undefined field being used, and decompiler says, to edit your struct accordingly:
Initial struct and field is at pad[y] and type int and where 0 <= y < x, y is index, x is length, it’s length in struct definitions, and index in dereferencing array:
```
struct example {
  char pad[x];
};
```
Now becomes:
```
struct example {
  char pad[y];
  int field_name;
  char pad[x-(y+sizeof(field_name))];
}
```
you can create enums and structs
can parse c header files to bring in type information
M to select what the magic number means
