18.8 to 14.8 seconds. The Pattern ISel is now often faster than the

Tell the SelectionDAG ISel to expand SEXTLOAD of i1 and i8, rather than

Combine the FP and Int ISD::LOAD codegen
Generate better code for constant pool loads
As a result, all of Shootout, and likely many other programs are now
working.

going on with copies between floating point and integer register files
