* tracepoint.c (tfile_get_trace_state_variable_value): Look for
the last matched 'V' blcok in trace frame. gdb/gdbserver: * tracepoint.c (traceframe_read_tsv): Look for the last matched 'V' block in trace frame. gdb/testsuite: * gdb.trace/tsv.exp (check_tsv): New. (top level): Save a tfile on current trace session. Call check_tsv on live target. Load the tfile with target tfile and call check_tsv again.
