* Add two new classes: WeakVH and AssertingVH. These are both "ValueHandles", Chris Lattner2009-03-311-2/+165
| | | | | | | | | | | | | | | | | | | | which are effectively smart pointers to Value*'s. They are both very light weight and simple, and react to values being destroyed or being RAUW'd. WeakVN does a best effort to follow a value around, including through RAUW operations and will get nulled out of the value is destroyed. This is useful for the eventual "metadata that references a value" work, because it is a reference to a value that does not show up on its use_* list. AssertingVH is a pointer that compiles down to a dumb raw pointer when assertions are disabled. When enabled, it emits an assertion if the pointed-to value is destroyed while it is still being referenced. This is very useful for Maps and other things, and should have caught the recent bugs in CallGraph and Reassociate, for example. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68149 91177308-0d34-0410-b5e6-96231b3b80d8

* Second installment of "BasicBlock operands to the back"Gabor Greif2009-03-133-9/+17
| | | | | | | | | | | | | | | | | | | changes. For InvokeInst now all arguments begin at op_begin(). The Callee, Cont and Fail are now faster to get by access relative to op_end(). This patch introduces some temporary uglyness in CallSite. Next I'll bring CallInst up to a similar scheme and then the uglyness will magically vanish. This patch also exposes all the reliance of the libraries on InvokeInst's operand ordering. I am thinking of taking care of that too. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66920 91177308-0d34-0410-b5e6-96231b3b80d8
* Rearrange operands of the BranchInst, to be able toGabor Greif2009-03-123-30/+105
| | | | | | | | | | | | | | | | | | | | | | | | | | 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
