Gabor Greif ae5a20a917 Rearrange operands of the BranchInst, to be able to ... access each with a fixed negative index from op_end(). This has two important implications: - getUser() will work faster, because there are less iterations for the waymarking algorithm to perform. This is important when running various analyses that want to determine callers of basic blocks. - getSuccessor() now runs faster, because the indirection via OperandList is not necessary: Uses corresponding to the successors are at fixed offset to "this". The price we pay is the slightly more complicated logic in the operator User::delete, as it has to pick up the information whether it has to free the memory of an original unconditional BranchInst or a BranchInst that was originally conditional, but has been shortened to unconditional. I was not able to come up with a nicer solution to this problem. (And rest assured, I tried *a lot*). Similar reorderings will follow for InvokeInst and CallInst. After that some optimizations to pred_iterator and CallSite will fall out naturally. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66815 91177308-0d34-0410-b5e6-96231b3b80d8		2009-03-12 18:34:49 +00:00
