I use the case to debug, I find that the min16float4 (0.00000000,0.00000000,0.00000000,0.00000000) 's type is VectorTyID, and when i add the code as below, it can be compiled successfully.

or its type should not be VectorTyID?

As this is a long-standing issue I'm afraid that we're unlikely to be able to spend time working on this in the short term. However, it looks like you have a fix! Would you be up for building a PR, including some test cases, for this fix? If so, we'd be happy to merge it.

Thanks!
