[llvm-commits] CVS: llvm/lib/Target/TargetSelectionDAG.td

[Nate Begeman]

Changes in directory llvm/lib/Target:

TargetSelectionDAG.td updated: 1.66 -> 1.67
---
Log message:

JumpTable support!  What this represents is working asm and jit support for
x86 and ppc for 100% dense switch statements when relocations are non-PIC.
This support will be extended and enhanced in the coming days to support
PIC, and less dense forms of jump tables.
