Ok

What I'm supposed to do about line length?
Any thread without a name is automatically assigned with the program name argv[0]. So Empty string could not be a problem here.

Sorry, I didn't got your point here. Could you please elaborate it a little more, as I am new to GDB.

This needs an introductory comment.

Mohsan>    if (print_thread_events)

Mohsan> +    printf_unfiltered (_("[New %s \"%s\"]\n"),

This line is too long.
Also, I think the output will be weird if the thread does not have a name.

Mohsan> +            printf_filtered (_("\nThread %d \"%s\" (%s):\n"),
Mohsan> +                             tp_array[k]->num,

Mohsan> +                             target_pid_to_str 
Mohsan> + (inferior_ptid));

Likewise concerning the no-name case.

Mohsan> +	  printf_filtered (_("\nThread %d \"%s\" (%s):\n"), tp->num, 
Mohsan> +thread_name (tp),

Too long, plus no-name.

Mohsan>    ui_out_text (uiout, "[Switching to thread ");
Mohsan>    ui_out_field_int (uiout, "new-thread-id", pid_to_thread_id 
Mohsan> (inferior_ptid));

Mohsan> +  ui_out_text (uiout, " \"");
Mohsan> +  ui_out_text (uiout, thread_name (tp));  ui_out_text (uiout, 
Mohsan> + "\" (");
Mohsan>    ui_out_text (uiout, target_pid_to_str (inferior_ptid));
Mohsan>    ui_out_text (uiout, ")]");

Two thoughts come to mind for the patch.

First, perhaps a single function for emitting the thread description would be better.  Then it could be normalized across all of gdb.

Second, it would be nice to use ui-out properly in such a function, so that MI can see the thread name distinctly from the other bits.
