Hi Chris, Thanks for the reply. I am actually interested in using the Intervals Analysis mainly to be able to do Region based analysis. In fact, I found that the way Intervals are defined mirror exactly the definition 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

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 anywhere. Here's what's going on in IntervalIterator.h:

ValGrind gives me some info, but I'm not great at memory stuff, and so I'm not sure what to make of it... This is code that worked for someone 8 months ago, and I'm just trying to get it to run on llvm 2.9 instead of 2.8, so the fact that it hasn't been working is frustrating. Anyway, my issues seem to stem from IntervalIterator, as seen below. I have a lot of similar issues

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...

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 %'

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:

Attached is a small patch to allow users of the PBQP allocator to optionally insert a custom pass. I believe it can be usefull to other users of the pbqp. I used it to undo some of the coalescer work, and make sure that I have different virtual registers, inserting a copy if necessary, to build a pair. I noticed an unexpected --- to me at least --- behaviour of the allocator. I have some
