* tracepoint.c (tfile_xfer_partial): If there's no traceframe selected, don't try iterating over the traceframe's blocks. (tfile_has_stack): If there's no traceframe selected, then there's no stack. (tfile_has_registers): If there's no traceframe selected, then there's no registers. gdb/testsuite/ * gdb.trace/tfile.exp: Test that with no traceframe selected, there's no stack or registers.
