> Hi,
> This patch extends the qXfer:traceframe-info object to report the set
> of collected trace state variables in the current traceframe.
> 
> Since VEC(int) is used in tracepoint.h, to avoid duplicated definition
> error, this patch also moves DEF_VEC_I(int) to gdb_vecs.h, and include
> it in other files instead of defining it by their own.
> 
> When GDB reads from trace file (tfile or ctf), the traceframe_ifo
> object should be updated for trace state variables as well.

The documentation parts are OK.  Thanks.
