# \brief GDB command line arguments for setting a breakpoint in the 'main()' function

# We set a break in the 'main()' function of a dynamically linked
# application by using the following gdb command sequence. It's important that
# the 'main()' breakpoint gets set before the 'sharedlibrary' command is
# executed. Otherwise the breakpoint would get set in ld.lib.so's main()
# function.

set gdb_cmds ""
# don't ask for y/n when loading a new symbol file
append gdb_cmds {-ex "set interactive-mode off" }
# set a breakpoint in the 'binary_ready_hook_for_gdb' function
append gdb_cmds {-ex "b binary_ready_hook_for_gdb" }
# continue execution until the breakpoint triggers
append gdb_cmds {-ex "c" }
# delete the 'binary_ready_hook_for_gdb' breakpoint
append gdb_cmds {-ex "delete 1" }
# load the symbols of the test application
append gdb_cmds "-ex \"file bin/$target_binary_name\" "
# set a breakpoint in the application's 'main()' function
append gdb_cmds {-ex "b main" }
# set search path for "sharedlibrary" to bin
