/** Calculate hash of the executable loaded segments of the first loaded object.

* It can be used for integrity checks.
|
|
|
|
|
* Does not work when ClickHouse is build as multiple shared libraries.
|
|
|
|
|
* Note: we don't hash all loaded readonly segments, because some of them are modified by 'strip'
|
|
|
|
|
* and we want something that survives 'strip'.
|
|
|
|
|
* Note: program behaviour can be affected not only by machine code but also by the data in these segments,
|
|
|
|
|
* so the integrity check is going to be incomplete.
