  17 # Test break points and single step on thread functions.
  18 #
  19 # Test Purpose:
  20 # - Test that breakpoints, continue in a threaded  application works.
  21 #   On powerpc64-unknown-linux-gnu system, running kernel version
  22 #   2.6.5-7.71-pseries64 this test is known to fail due to kernel bug
  23 #   in ptrace system call.
  24 #
  25 # Test Strategy:
  26 # - thread_check.c creates 2 threads
  27 # - start gdb
  28 # - create 2 breakpoints #1 main() #2 tf() (the thread function)
  29 # - run gdb till #1 main() breakpoint is reached
  30 # - continue to breakpoint #2 tf()
  31 # - delete all breakpoints
  32 # - exit gdb.
