17 | # the shared libraries of inferior are loaded and unloaded. | |
18 | # There are two parameters in this test: | |
19 | # - SOLIB_COUNT is the number of shared libraries program will load | |
20 | # and unload | |
21 | # - SOLIB_DLCLOSE_REVERSED_ORDER controls the order of dlclose shared | |
22 | # libraries. If it is set, program dlclose shared libraries in a | |
23 | # reversed order of loading. | |
