For example, see the core 5 manual page for NetBSD. Not so much gdb as the bfd library used by gdb , binutils , etc. You could then parse the corresponding file. Kenshoto's open source VDB debugger uses this approach, if you can read python it is a good example. Stack Overflow for Teams — Collaborate and share knowledge with a private group.

Are you referring to the object code format that gcc produces or the format of the final executable, in which case that would be ELF, or something else? A newer answer for this question is here.

In the XML, binary, and in-memory stores, evaluation of the predicate and sort descriptors is performed in Objective-C with access to all Cocoa functionality, including the comparison methods on NSString. The SQLite store, on the other hand, compiles the predicate and sort descriptors to SQL and evaluates the result in the database itself.
This is done primarily for performance, but it means that evaluation happens in a non-Cocoa environment, and so sort descriptors or predicates that rely on Cocoa cannot work. The latter is Finder-like sorting and what most people should use most of the time. In addition, you cannot sort on transient properties using the SQLite store.
There are additional constraints on the predicates you can use with the SQLite store:. For example, no toOne. CoreData supports a noindex: that can be used to drop indices in queries passed to SQLite. This is done primarily for performance reasons: SQLite uses a limited number of indices per query, and noindex: allows the user to preferentially specify which indexes should not be used. See NSPredicate documentation regarding function expressions.
The SQLite store supports reading data from a file that resides on any type of file system. However, the SQLite store does not generally support writing directly to file systems that do not implement byte-range locking.
Simply deleting a record from an SQLite store does not necessarily result in a reduction in the size of the file. Similarly, the file size is reduced if you remove an item that itself occupies multiple pages such as a thumbnail image. An SQLite file is organized as a collection of pages.
The data within those pages is managed through B-trees, not as simple fixed-length records. This format is more efficient for searching and for overall storage, because it allows SQLite to optimize how it stores both data and indexes in a single file.
This format does not support versioning, perspectives, or the full richness of CORE's stored views which provide the presentation layer to complement the technical content. This format does not support attribute change tracking who last changed an attribute and when , versioning, perspectives, or the full richness of CORE's stored views which provide the presentation layer to complement the technical content.
The Export drop-down presents the list of export scenarios supported. These scenarios represent a specific combination of options packaged to best support standard export cases.
As an export is selected from the drop-down, the Options pane will shift to show the applicable settings for the export scenario.
If the pane is greyed out, the options are informational only, informing you of what options are included in the scenario. If the pane is white, you may change the options presented. The options vary for XML and legacy exports. XML exports provide not only the richest data set but also the richest options. Project Backup - the default export scenario, project backup creates a full XML backup file containing the projects selected in the projects pane.
This includes the complete schema definitions, the database, and utility information folders, filters, hierarchy definitions, icon templates, and sort definitions. When backing up or archiving a specific project, this is the best option.
Note, however, that this does not include the defined users and groups. Therefore, if you are archiving a project, you should also archive a user and group export. Project Baseline - creates a full export representation equivalent to Project Backup but proceeds to erase the merge history after the import is completed.
This option is valuable when working with distributed team members who will be modifying the system definition in parallel without benefit of the CORE Server to enable collaboration.
