[LLVMdev] If Conversion and predicated returns
...alyzeBranch be enhanced to somehow indicate conditional returns?
Alternatively, the diamond conversion routine contains this:
// RemoveExtraEdges won't work if the block has an unanalyzable branch,
// which can happen here if TailBB is unanalyzable and is merged, so
// explicitly remove BBI1 and BBI2 as successors.
BBI.BB->removeSuccessor(BBI1->BB);
BBI.BB->removeSuccessor(BBI2->BB);
RemoveExtraEdges(BBI);
should something similar be added prior to the calls to RemoveExtraEdges in the simple and triangle conversion routines?
Thanks in advance,
Hal

Both of these...
