-device <device_type> Target device. -device <device_type> Target device.
<device_type> can be: %s <device_type> can be: %s
If multiple target devices are provided, ocloc
will compile for each of these targets and will
create a fatbinary archive that contains all of
device binaries produced this way.
Supported -device patterns examples :
-device skl ; will compile 1 target
-device skl,icllp ; will compile 2 targets
-device skl-icllp ; will compile all targets
in range (inclusive)
-device skl- ; will compile all targets
newer/same as provided
-device -skl ; will compile all targets
older/same as provided
-device gen9 ; will compile all targets
matching the same gen
-device gen9-gen11 ; will compile all targets

-device -gen9 ; will compile all targets
