Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit X-SW-Source: 2003-09/txt/msg00293.txt.bz2 Hi All, I was reading the GDB manual and realized that there is,practically, no tracepoint support provided by GDB since this support is available only for remote targets and for the latter , GDB doesn't provide any stub (like gdbserver) which has tracepoint support. I have a few doubts in mind regarding this : 1. Why does GDB not provide this support for local host ? 2. Is it not the case that the features (supposed to be) provided by tracepoints can be done using breakpoint features only (for instance , we can specify COMMANDS for a breakpoint just as we can specify ACTIONS for tracepoints) ? 3. Does tracepoint use the same TRAP (or ILLEGAL ) instruction mechanism for tracepoints as it does for breakpoints? if not, what does it do? 4. Does this trace support available in any other GDB supported by other vendors? Regards, Saravanan
