Id descriptors are computed as a recursive hash of all instructions used to define an id. Descriptors are invarint of actual id values and the similar code in different files would produce the same descriptors. Multiple ids can have the same descriptor. For example %1 = OpConstant %u32 1 %2 = OpConstant %u32 1 would produce two ids with the same descriptor. But %3 = OpConstant %s32 1 %4 = OpConstant %u32 2 would have descriptors different from %1 and %2. Descriptors will be used as handles of move-to-front sequences in SPIR-V compression.
