  18 # It's possible to have a program that contains two compilation units
  19 # for the same source file name, that have code at different lines.
  20 # For example, in this test, we compile expand-psymtabs.c twice with
  21 # different preprocessor symbols #defined; the first .o only has
  22 # 'main' at some earlier source lines, while the second .o only has
  23 # 'foo' at later source lines.  So when setting breakpoints by line
  24 # number, which full symtab we need depends on the line number in
  25 # question.
  26 #
  27 # This test is meant to verify that, even with lazy partial symtab
  28 # reading in effect, GDB can set breakpoints by line number
  29 # successfully in either compilation unit.
