Subject: uLUt library updated from other projects.
X-Git-Tag: ul_drv-0.8.0-release~38
X-Git-Url: https://rtime.felk.cvut.cz/gitweb/ulut.git/commitdiff_plain/b2534e8c42d54ab438c6b631d4e2a3c7737518e6

uLUt library updated from other projects.

Added support for cyclic variables comparison
  ul_cyclic_gt
  ul_cyclic_ge
This is usable mainly to compare time counters and other
variables which are expected to overflow and support overflow
arithmetics.
