Re: [PATCH] Some middle-end improvements for bitfield handling

I don't follow.  How could it do that for fields that were not arrays?
We don't currently support arrays of bitfields.

For example, you may have an array of 32-bit structs with bitfields and a loop body performing operations on those fields. When you lower these operations to operations on 32-bit unsigned integers, they might be a candidate for vectorizing.
