63# Test basic opaque structure handling (statically).
64# The ordering of the tests is significant. We first try the things that
65# might fail if gdb fails to connect the uses of opaque structures to
66# the actual opaque structure definition.
67
68# When we start up, gdb sets the file containing main() as the current
69# source file. The actual structure foo is defined in a different file.
70# A pointer (foop) to an instance of the opaque struct is defined in the same
71# source file as main(). Ensure that gdb correctly "connected" the definition
72# in the other file with the pointer to the opaque struct in the file containing
73# "foop".
