| | 19 | .Sh DESCRIPTION |
| | 20 | Executables built for Mac OS X 10.6 and later have a new format for the |
| | 21 | information in the __LINKEDIT segment. The dyldinfo tool will display |
| | 22 | that information. |
| | 23 | .Pp |
| | 24 | The options are as follows: |
| | 25 | .Bl -tag -width indent |
| | 26 | .It Fl arch Ar arch |
| | 27 | Only display the specified architecture. Other architectures in a universal image are ignored. |
| | 28 | .It Fl dylibs |
| | 29 | Display the table of dylibs on which this image depends. |
| | 30 | .It Fl rebase |
| | 31 | Display the table of rebasing information. Rebasing is what dyld does when an image is |
| | 32 | not loaded at its preferred address. Typically, this involves updating pointers in the __DATA |
| | 33 | segment which point within the image. |
| | 34 | .It Fl bind |
| | 35 | Display the table of binding information. These are the symbolic fix ups that dyld must |
| | 36 | do when an image is loaded. |
| | 37 | .It Fl weak_bind |
| | 38 | Display the table of weak binding information. Typically, only C++ progams will have any |
| | 39 | weak binding. These are symbols which dyld must unique accross all images. |
| | 40 | .It Fl lazy_bind |
| | 41 | Display the table of lazy binding information. These are symbols which dyld delays binding |
| | 42 | until they are first used. Lazy binding is automatically used for all function calls to |
| | 43 | functions in some external dylib. |
| | 44 | .It Fl export |
| | 45 | Display the table symbols which this image exports. |
| | 46 | .It Fl opcodes |
| | 47 | Display the low level opcodes used to encode all rebase and binding information. |
| | 48 | .It Fl function_starts |
| | 49 | Decodes the list of function start addresses. |
