[-fixup_chain_details] [-symbolic_fixups] [-validate_only]
The dyld_info tool will display information that dyld uses from binaries.
It supports fixups information encoded as opcode based or as chained
If the tool is run with no options, it defaults to the common options
(-platform -segments -dependents).
The tool can be run with paths to dylibs that are in the dyld cache and not
The options are as follows:
Only display the specified architecture. Other architectures in a
universal image are ignored.
Display the platform (e.g. macOS, iOS) that the binary was built
Display all segments and sections with size info.
Display all dylibs that the binary is linked against.
-inits Display all static initializers and Objective-C +load methods.
Display all exported symbols.
Display all imported symbols.
-objc Display the Objective-C classes and categories defined.
Display a simple table of fixup locations and what dyld will set
If the binary uses chained fixups, displays the format of the
chains and the starts.
Display a table of all the raw fixup chain bits and their meanings.
Display all fixups, grouped by data symbol.
Display nothing if binary is valid, or information about what parts
