<p dir="auto" style="color: #333238; margin: 0 0 16px;" align="initial">These memory benchmark programs are not supposed to run (*.norun.exe).
Instead, they can be analysed on the host system to measure the memory usage of
features. See the membench module of rtems-central, for example:</p>

the change in bytes of the section sizes with respect to the reference memory
benchmark program of the first row.
