[LLVMdev] Bug in BranchFolding.cpp:OptimizeBlock
...four end with conditional branches to an early return,
as specified with initial.dot.
TailMergeBlocks in BranchFolding::runOnMachineFunction merges the 4
early return blocks to a single basic block and numbers renumbers them,
as specified with tailmerge.dot.
When it runs optimize block on the if.end14 block, it enters the above
segment of code, removing it and replacing it with FallThrough, which is
NOT its successor block and links two blocks changing the structure of
the program as shown in Optimizeblock.dot.
I've attached a possible solution as a p4diff as I don't have svn setup
