This part was never answered on the semantics here?
And the clang documentation for
frandomize-layout-seed/frandomize-layout-seed-file is weak.
Say you have (assuming all three have the randomize attribute on it)
header1:
```
struct a
{
...
};
```
header2:
```
struct b
{
...
};
```
You include header1 before header2 in TU1 but in TU2 the opposite is true.
Or say you sometimes include header3 which contains `struct c{...};`
how do you set the seed for each struct?
This is not documented at all.
The documentation for these 2 options in clang just say:
"File holding the seed used by the randomize structure layout feature"
Nothing more. The attribute randomize_layout is not even documented either.
