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.
