# This test shows the importance of not corrupting the order of line
|
|
# table information. When multiple lines are given for the same
|
|
# address the compiler usually lists these in the order in which we
|
|
# would expect to encounter them. When stepping through nested inline
|
|
# frames the last line given for an address is assumed by GDB to be
|
|
# the most inner frame, and this is what GDB displays.
|
|
#
|
|
# If we corrupt the order of the line table entries then GDB will
|
|
# display the wrong line as being the inner most frame.
