## 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.
