IDA will calculate checksums for all non-trivial functions in the database and send it to Lumina. This information will be used to match and retrieve metadata, which will be automatically applied.
Please note that this may overwrite your changes, so taking a database snapshot and saving the database before invoking this command is a good idea.
By non-trivial functions we mean:
- long enough functions (>=16 bytes) - non-library functions - non-imported functions (functions with real body)See also View all metadata, which allows the user to interactively apply metadata.
