/* Add a pattern matching ".foo" for every "foo" in a version script.
|
|
|
|
|
|
|
|
The reason for doing this is that many shared library version
|
|
|
|
scripts export a selected set of functions or data symbols, forcing
|
|
|
|
others local. eg.
|
|
|
|
|
|
|
|
. VERS_1 {
|
|
|
|
. global:
|
|
|
|
. this; that; some; thing;
|
|
|
|
. local:
|
|
|
|
. *;
|
|
|
|
. };
|
|
|
|
|
|
|
|
To make the above work for PowerPC64, we need to export ".this",
|
|
|
|
".that" and so on, otherwise only the function descriptor syms are
|
|
|
|
exported. Lack of an exported function code sym may cause a
|
|
|
|
definition to be pulled in from a static library. */
