Bug ID: 45949
Summary: [X86] SSE intrinsic instructions selected using
selectScalarSSELoad don't get MachineMemoryOperands
Product: libraries
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: enhancement
Priority: P
Component: Backend: X86
Assignee: unassignedb...@nondot.org
Reporter: craig.top...@gmail.com
CC: craig.top...@gmail.com, llvm-bugs@lists.llvm.org,

Using a complex pattern like this doesn't give any mechanism for supplying a
MemRef to use on the final isel MachineSDNode.
We could try to invent a mechanism. Or maybe do a post process combine to fold
the load instead after initial selection. Or do custom isel for the whole
instruction. Or maybe remove it from isel and just use the peephole pass? Not
sure if it can get all cases or not.
