Changes in directory llvm/include/llvm/CodeGen:
SelectionDAGISel.h updated: 1.13 -> 1.14
---
Log message:
Fix the updating of the machine CFG when a PHI node was in a successor of
the jump table's range check block. This re-enables 100% dense jump tables
by default on PPC & x86

Diffs of the changes: (+6 -3)
