| ## LLD tries to resolve dependent library specifiers in the following order: |
| ## 1) The literal name in the current working directory. |
| ## 2) The literal name in a library search path. |
| ## 3) The name, prefixed with "lib" and suffixed with ".so" or ".a" in a |
| ## library search path. This means that a directive of "foo.a" could lead |
| ## to a library named "libfoo.a.a" being linked in. |
| ## When using library search paths for dependent libraries, LLD follows the same |
| ## rules as for libraries specified on the command line. |
