# When compiling with DWARF, gcc only emits the debug definition of a class in
# the compilation unit where it is defined if the class has a virtual ctor/dtor.
# We can take advantage of that when we process the DWARF debug map in the
# executable to note which CU has the class definition.  Then when the user
# examines an object of that class w/o visiting the defining CU, gdb finds the
# type in the psymtab list and expands the defining CU's symtab, picking up the
# definition.

# In short, test that gdb knows the definition of class test1abcdefg without
# previously expanding the psymtab for single-def-classdef.cc.
