Hi, I wrote a Function pass that requires the IntervalPartition pass in order to obtain the set of intervals for every function: virtual void getAnalysisUsage(AnalysisUsage &AU) const { AU.addRequired<IntervalPartition>(); } and get a handle to it in the runOnFunction method of my CustomPass: bool CustomPass::runOnFunction(Function& F) {...

I've done first round of refactoring and currently writing some code of mine that uses IntervalPartition which should uncover any remaining issues. When done, I'll submit a patch. Probably I should describe the approach I taken. The problem with current Interval class is that it contains vector<BasicBlock*> and that Successor/Predecessor lists also point to basic block. That make it r...

...efinition of a Region in the second edition of the Dragon Book (Section 9.7 on Region-Based Analysis), so it will be great if the Intervals related code still lives on in LLVM :). I found a fix for the bug, which may not be very elegant, but works none the less. Firstly, the destroy() method in IntervalPartition.cpp did not clear the Intervals vector and secondly, since destroy() is only called from the destructor the state of the intervals is maintained across different runOnFunction() calls. So now I clear the Intervals vector in destroy() and call destroy() to start on a clean state before doing the...

Hi, it looks like the IntervalPartition does not work as expected when constructed from another interval partition. Say, I have built an interval partition from function, and the first interval has two basic blocks. When I create second order partition and print all intervals, the second basic block of the function is not seen any...

...lp me out here. I want to locate the Interval that begins with the call to the "magic" begin(), and ends with the call to the "magic" end(), if it exists. If there is no such valid interval, then I want to detect that and return an error. Can I make this happen by using the IntervalPartition pass? It looks like LLVM has some functionality that I could use *some where.* I just can't quite figure out how to make use of it. Thanks, Evan Jones

Hello, I've been stuck with a problem for about a month, and it has stumped everyone in my lab. I have a function pass that runs, and when it finishes and opt goes to return, I get: While deleting: void % An asserting value handle still pointed to this value! UNREACHABLE executed at /x/grwright/llvm/llvm-2.9/lib/VMCore/Value.cpp:569! On a simple test case, the error becomes 'i32 %'

Is there structural analysis as described in Advanced compiler design & implementation(Muchnick) in LLVM now? I only find interval analysis in IntervalPartition.cpp now. -------------- next part -------------- An HTML attachment was scrubbed...

I have two very specific questions about LLVM, but first let me give you the general overview of what I am trying to achieve. I have some section of a function that I want to replace with a function call to a brand new function. For example, I want to take the following function: function foo: code A <--- CUT code B <--- CUT code C and (approximately) convert it into: function foo:
