Migration of __activemask is not supported. You may need to use 0xffffffff instead or adjust the code.

There is currently no functional equivalent of

__activemask()

in SYCL. If there is no flow control that will make the thread inactive, 0xffffffff can be used as an alternative. Otherwise, you may need to rewrite the thread logic.

Check if 0xffffffff can be used instead of

__activemask()

. If it cannot be used, redesign the thread logic.
