This code had one purpose only, feed timing information into a test and was not used by anything else. The custom trace points unfortunatly were not accurate and this test was delivering informatin that conflicted with other tests we have due to placement of such trace points in the architecture and kernel code. For such measurements we are planning to use the tracing functionality in a special mode that would be used for metrics without polluting the architecture and kernel code with additional tracing and timing code. Furthermore, much of the assembly code used had issues. Signed-off-by: Anas Nashif <anas.nashif@intel.com> Signed-off-by: Daniel Leung <daniel.leung@intel.com>
