Like last January. I guess this thread initiated by Jeff Johnston is what you were referring to: http://sources.redhat.com/ml/gdb-patches/2004-12/msg00256.html It was really a long thread, spanning several monthes. My reading of these post tell me that it is partly approved at some point, and later held off for observer issue. Is that right? Does that kind of issue still hold in current gdb source code? Does anybody has interest in looking into these question again? I am recently working on h/w watchpoint support for ppc440 board. Customers are also inquirying if multi-threaded program works ok with h/w watchpoint. I believe this feature is quite desirable for multi threaded program. Regards - Wu Zhou
