411 | /* Add a pattern matching ".foo" for every "foo" in a version script. |
412 | ||
413 | The reason for doing this is that many shared library version | |
414 | scripts export a selected set of functions or data symbols, forcing | |
415 | others local. eg. | |
416 | ||
417 | . VERS_1 { | |
418 | . global: | |
419 | . this; that; some; thing; | |
420 | . local: | |
421 | . *; | |
422 | . }; | |
423 | ||
424 | To make the above work for PowerPC64, we need to export ".this", | |
425 | ".that" and so on, otherwise only the function descriptor syms are | |
426 | exported. Lack of an exported function code sym may cause a | |
427 | definition to be pulled in from a static library. */ | |
