# 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:

# - thread_check.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.
