            Bug ID: 34873
           Summary: [X86] Execution domain fixing should be able to turn
                    PBLENDW into BLENDPS/BLENDPD
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Backend: X86
          Assignee: unassignedbugs at nondot.org

With SSE41 the only integer domain blend that uses an immediate is BLENDW which
has 16-bit elements. Ideally, execution domain fixing should be able to convert
it to floating point when the element size is really at least 32-bits, but that
requires rewriting the immediate. This is more than what the simple table based
domain fixing can currently do.
