  23 # It's possible to have a program that contains two compilation units
  24 # for the same source file name, that have code at different lines.
  25 # For example, in this test, we compile expand-psymtabs.c twice with
  26 # different preprocessor symbols #defined; the first .o only has
  27 # 'main' at some earlier source lines, while the second .o only has
  28 # 'foo' at later source lines.  So when setting breakpoints by line
  29 # number, which full symtab we need depends on the line number in
  30 # question.
  31 #
  32 # This test is meant to verify that, even with lazy partial symtab
  33 # reading in effect, GDB can set breakpoints by line number
  34 # successfully in either compilation unit.
