Nate Begeman f15485a8d0 SelectionDAGISel can now natively handle Switch instructions, in the same ... manner that the LowerSwitch LLVM to LLVM pass does: emitting a binary search tree of basic blocks. The new approach has several advantages: it is faster, it generates significantly smaller code in many cases, and it paves the way for implementing dense switch tables as a jump table by handling switches directly in the instruction selector. This functionality is currently only enabled on x86, but should be safe for every target. In anticipation of making it the default, the cfg is now properly updated in the x86, ppc, and sparc select lowering code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@27156 91177308-0d34-0410-b5e6-96231b3b80d8		2006-03-27 01:32:24 +00:00
