Last change on this file since e0938c2 was e6b31b27, checked in by Joel Sherrill <joel.sherrill@…>, on 05/27/15 at 15:13:58

Remove use ticks for statistics configure option.

This was obsolete and broken based upon recent time keeping changes.

Thie build option was previously enabled by adding
USE_TICKS_FOR_STATISTICS=1 to the configure command line.

This propagated into the code as preprocessor conditionals
using the RTEMS_USE_TICKS_FOR_STATISTICS conditional.
