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