* Revert a portion of Dan's change r71018 that I'm convinced is wrong.Bob Wilson2009-05-131-1/+1
| | | | | | | | | | | | | | | | | | | | Dan was trying to catch the case where a basic block ends with a conditional branch to the fall-through block. In this case, all the instructions have been moved out of FromBBI, leaving it empty. It cannot end with a conditional branch. As the existing comment indicates, it will always fall through to the next block. If the block already had the next block (NBB) listed as a successor, the preceding loop has a check for that and does not remove it. Thus, we need to check and add the successor only when it is not already listed. With Dan's change, the empty block often ends up with the fall-through successor listed twice. This exposed the problem in pr4195, where CodePlacementOpt did not handle the same predecessor listed more than once. It is also at least partially responsible for pr4202 and probably a similar issue with Thumb branches being out of range. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@71742 91177308-0d34-0410-b5e6-96231b3b80d8

Remembering what all of those booleans mean isn't easy, especially if you aren't spending all of your time in that code. I took Jakob's suggestion and made it illegal to pass in "true" for the flag. This should hopefully prevent any unintended misuse of this (by reverting to the old way of using addReg()). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@71722 91177308-0d34-0410-b5e6-96231b3b80d8
