75 | # Try printing "this_version_num". There are two global variables | |
c56e7c43 JB |
76 | # with that name, and some systems such as GNU/Linux merge them |
77 | # into one single entity, while some other systems such as Windows | |
78 | # keep them separate. In the first situation, we have to verify | |
79 | # that GDB does not randomly select the wrong instance. And in | |
80 | # the second case, we have to verify that GDB prints the value | |
81 | # of the instance from the current debugging context (the shared | |
82 | # library currently being debugged). | |
83 | # | |
84 | # We perform two tests: The first print test verifies that we are | |
85 | # doing things right when the partial symtab hasn't been expanded. | |
86 | # And the second print test will do the same, but after the partial | |
87 | # symtab has been expanded. | |
88 | # | |
89 | # To avoid adding target-specific code in this testcase, the program | |
90 | # sets a local variable named 'v' with the value of the global | |
91 | # variable 'this_version_number'. This allows us to compare the value | |
92 | # that GDB thinks 'this_version_num' has, against the actual value | |
93 | # seen by the program itself. | |
