...efInfo(). The situation is that Mod/Ref info is called with a CallSite and GlobalVariable argument, where the global is passed as an argument to the call. Furthermore, the callee function does *nothing* with this global but to pass it on to another callee function. In the last callee, the BottomUp DSNode is the same as the GlobalGraphs' node (very detailed; including a link to another DSNode), but in the top function and the intermediate callee, the global is not accessed and its DSNode is simply "I", without a type. An error manifests itself in DataStructureAA, as the i...

I see that there are several options to influence instruction scheduling, but there doesn't seem to be a lot of information about what they do, for example: -misched-topdown -misched-bottomup The description in MachineScheduler.cpp says: "Force top-down list scheduling" and "Force bottom-up list scheduling" Which isn't too helpful - where might I want to use these? Under what conditions might they improve an instruction schedule? Similar questions for the ins...

...patch was submitted and the time I got around to looking at it), and there was only 1 user of ds-aa, so making it work was low priority. How you should use the DSA analysis depends on what you're doing. For intra-procedural alias analysis queries, you can use the DSGraph straight from the BottomUp or TopDown DSA analysis passes. For both intra- and inter-procedural alias analysis queries, you can use the DSNodeEquivs pass. If you need a shape graph, you can use the DSGraph interface directly. If you could tell me how you want to use DSA, I can explain which approach to use and how to...

Greeting. I am working on one DSA related project. Got several questions about LLVM's DSA analysis: 1. I looked through the llvm doc, it seems "-ds-aa" option is the one I should use. (http://llvm.org/docs/AliasAnalysis.html#the-ds-aa-pass). however based on the poolalloc's svn history, this option was removed on (or before) 2011. May I know why this one was removed ? and is

...aper for more details about time complexity and performance http://web.cs.ucla.edu/~zaniolo/papers/chp%253A10.1007%252F978-3-642-37456-2_10.pdf for implementing it,we can use Documentsource class in our previous clustering approach and create a binary tree and perform and topdownsplitting and then bottomup merging. First we have to implement feature extraction from text document(TFIDF would be a good choice) which is implemented in xapian weighting schemes. Then we will implement function to compute distances between documents based on normalized TF-IDF Matrix. Based on distances we will initially as...

Hello All,I am Nirmal Singhania from NIIT University,India. I am interested in Clustering of search results Topic. I have been in field of practical machine learning and information retrieval from quite some time. I took various courses/MOOC on Information retrieval and Text Mining and have been working on real life datasets(KDD99,AWID,Movielens). Because the problems you face in real life ML/IR

...ust checked in a rather large change to the data structure graph representation. Here are the bonuses of the new representation: 1. Only the DSNode interface changed, mostly in implementation details, so hopefully client code shouldn't be effected. As a metric, nothing had to change in BottomUp or TopDownClosure.cpp for the new representation. The biggest change is that the getLink(...) methods now return a reference to a DSNodeHandle instead of a pointer. 2. The new representation is much smaller and less computationally intensive to update, meaning that the datastructure analys...

Dear Developers, In current implementation of validity method, objects are first coerced to superclass (slots are striped). Thus, it is not possible to write validity method which would perform some checks on children slots. Say, I want to check if number of slots in a class is equal to "n": setClass("A", representation(a="numeric", n="integer"),
