16 | # The purpose of this testcase is to verify that we can "next" over |
17 | # a call to a function provided by one shared library made from another | |
18 | # shared library, and that GDB stops at the expected location. In this | |
19 | # case, the call is made from sub1 (provided by libdso1) and we are | |
20 | # calling sub2 (provided by libdso2). | |
21 | # | |
22 | # Note that, while this is not the main purpose of this testcase, it | |
23 | # also happens to exercise an issue with displaced stepping on amd64 | |
24 | # when libdso1 is mapped at an address greater than 0xffffffff. | |
