dyldinfo(1) BSD General Commands Manual dyldinfo(1)
NAME
dyldinfo -- Displays information used by dyld in an executable
SYNOPSIS
dyldinfo [-arch arch-name] [-rebase] [-bind] [-weak_bind] [-lazy_bind] [-export] [-opcodes] file(s)
DESCRIPTION
Executables built for Mac OS X 10.6 and later have a new format for the information in the __LINKEDIT
segment. The dyldinfo tool will display that information.
The options are as follows:
-arch arch
Only display the specified architecture. Other architectures in a universal image are ignored.
-rebase
Display the table of rebasing information. Rebasing is what dyld does when an image is not
loaded at its preferred address. Typically, this involves updating pointers in the __DATA seg-ment segment
ment which are point within the image.
-bind Display the table of binding information. These are the symbolic fix ups that dyld must do
when an image is loaded.
-weak_bind
Display the table of weak binding information. Typically, only C++ progams will have any weak
binding. These are symbols which dyld must unique accross all images.
-lazy_bind
Display the table of lazy binding information. These are symbols which dyld delays binding
until they are first used. Lazy binding is automatically used for all function calls to func-tions functions
tions in some external dylib.
-export
Display the table symbols which this image exports.
-opcodes
Display the low level opcodes used to encode all rebase and binding information.
