  16 # Test to see that GDB reports the correct function name when stopping
  17 # in a function with several assembly-defined labels; see the test
  18 # case asmlabel.c.
  19 #
  20 # When setting and then continuing to a breakpoint at either location
  21 # L1 or L2 - again, see the code - we want to make sure that GDB
  22 # correctly reports that it's in main, like this:
  23 #
  24 # Breakpoint 2, main (argc=1, argv=0x7fffffffe408) at asmlabel.c:26
  25 # 26        v = 1;                /* set L1 breakpoint here */
  26 #
  27 # This test case was written to test for a bug in which GDB printed
  28 # the following instead:
  29 #
  30 # Breakpoint 2, L1 () at asmlabel.c:26
  31 # 26        v = 1;                /* set L1 breakpoint here */
