- Organization: TCS-HP
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?
