CHANGES:
File: lib/CodeGen/SelectionDAG/SelectionDAGBuilder.cpp
At: Wed 22 Sep 2010 23:56:24
Changed By: evancheng
Comments: SDISel should not optimize a unconditional branch following a conditional branch
when the unconditional branch destination is the fallthrough block. The
canonicalization makes it easier to allow optimizations on DAGs to invert
conditional branches. The branch folding pass (and AnalyzeBranch) will clean up
the unnecessary unconditional branches later.

This is one of the patches leading up to disabling codegen prepare critical edge
splitting.

File: lib/CodeGen/MachineSink.cpp
At: Wed 22 Sep 2010 23:56:24
Changed By: evancheng
Comments: Don't sink insert_subreg, subreg_to_reg, reg_sequence. They are meant to be
close to their sources to facilitate coalescing.
Properties: 




File: lib/Target/ARM/ARMBaseInstrInfo.cpp
At: Wed 22 Sep 2010 23:56:24
Changed By: evancheng
Comments: If there are multiple unconditional branches terminating a block, eliminate all
but the first one. Those will never be executed. There was logic to do this
but it was faulty.
