+# Test break points and single step on thread functions.
+# 
+# Test Purpose:
+# - Test that breakpoints, continue in a threaded  application works. 
+#   On powerpc64-unknown-linux-gnu system, running kernel version
+#   2.6.5-7.71-pseries64 this test is known to fail due to kernel bug
+#   in ptrace system call.
+#
+# Test Strategy:
+# - tbug.c creates 2 threads
+# - start gdb 
+# - create 2 breakpoints #1 main() #2 tf() (the thread function)
+# - run gdb till #1 main() breakpoint is reached
+# - continue to breakpoint #2 tf()
+# - delete all breakpoints 
+# - exit gdb.
