Dan Gohman f350b277f3 Move the point at which FastISel taps into the SelectionDAGISel ... process up to a higher level. This allows FastISel to leverage more of SelectionDAGISel's infastructure, such as updating Machine PHI nodes. Also, implement transitioning from SDISel back to FastISel in the middle of a block, so it's now possible to go back and forth. This allows FastISel to hand individual CallInsts and other complicated things off to SDISel to handle, while handling the rest of the block itself. To help support this, reorganize the SelectionDAG class so that it is allocated once and reused throughout a function, instead of being completely reallocated for each block. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55219 91177308-0d34-0410-b5e6-96231b3b80d8		2008-08-23 02:25:05 +00:00
