Bug ID: 38057
Summary: DAGCombiner::visitREM - improve vector support
Product: libraries
Version: trunk
Hardware: PC
OS: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: Common Code Generator Code
Assignee: unassignedbugs at nondot.org

Expansion of SREM/UREM with X%C to the equivalent of X-X/C*C is only setup for
scalars/constant splats - we should be able to handle non-uniform (non-zero)
vectors as well.
