i1 true ^= -1 in DAG matcher?
A constant i1 is stored as a one bit APInt wrapped in a ConstantInt which is then wrapped in ConstantSDNode for SelectionDAG. The BUILD_VECTOR will just point to the same ConstantSDNode for each element. There is no concept of a sign in the storage. It's just a bit. Whether or not its treated as 1 or negative 1 is going to depend on the code looking at the value including printing code. And

[X86][AVX512] RFC: make i1 illegal in the Codegen
...s on and off. As for supporting BUILD_VECTOR, EXTRACT_VEC_ELEMENT and INSERT_VEC_ELEMENT, we believe we can support these operations even when i1 is illegal and the vectors of i1 *are* legal by using the i8 type instead of i1, as it should be implicitly truncated/extended to the element type of the vNi1 vectors. I am now working on a patch that will implement this approach. Would appreciate to get feedback and comments.

Quick question...
Hi, Here's the scenario. I want to set up a mailbox so that when mail sent to the address is piped to a processing application, instead of going to a mailbox. One way I can do this is to set up a mailbox and then have an application that checks to see if there's mail and then processes it. (Old school Unix script) Is there a way to set it up with dovecot? (Cleaner solution) Thx
