There was a problem hiding this comment.
Makes sense, the zero register doesn't need to come from memory and you probably even already have a zero'd register somewhere so using the imm 3 bits instead of constructing a full 3-lane mask from memory is probably a nice win.

I looked in a few other places where I use the same mask. Most of those case already have SSE4 replacements that use different instructions. |
