SPIR-V codegen was not emitting correct code for OpControlBarrier. This manifested in the test_ewise.py unit test failing for test_multiple_cache_write() on Windows 10.
OpControlBarrier expects ids of integers, not the integers themselves. The fix for this is to generate constants for each required id.
