I think this assertion failure may be caused by the getAnalysisUsage(). Mine is like the following: class myclass : public ModulePass{ ... virtual void getAnalysisUsage(AnalysisUsage &AU) const { AU.addRequired<LoopInfo>(); } ... } Is it enough? Thanks!

Dear all, Is there a way to check whether we can go from A to B within a function when I'm writing a pass? Thanks. Best, --Wenbin -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.llvm.org/pipermail/llvm-dev/attachments/20100827/8cf26762/attachment.html>

I'll try the trunk, as well as check my code again. If indeed it's not fixed, I'll try to post a triggering case here.

...I want to recognize an assignment statement in the source code, can we quickly find all the related IR instructions according to a 'store'? E.g., i = j +k + m[5] in IR will have some loads and some getelementptrs. Can we define which IRs are related to this assignment? Thanks.

...ntptr %ST* %s, i32 1, i32 2, i32 1, i32 5, i32 13 But when I copied the code and compile it myself (using v2.7), I got five getelementptr instructions, which are just like the equivalent code given later in the document. In the case above, why the resulting IRs are different? Thanks a lot.Regards,--Wenbin -------------- next part -------------- An HTML attachment was scrubbed...

Hi all, I hope you guys can help me out. I got a problem with using function CURL. I did Set(CURL=${CURL(URL)}); but the URL I was using is https, so when I generated the call, the CURL function could not get access to that https://URL server. What should I do with it? Thank you very much

...do some analysis on the IR. For a instruction, e.g., a BinaryOperator, can I have the reference of an Operator from it? Now I can use getOpcode() or getOpcodeName() to have unsigned int or string. But can I have a Operator or specifically AddOperator as the return value? Thanks. Regards, --Wenbin -------------- next part -------------- An HTML attachment was scrubbed...

Hi all, While working on a loadable Alias Analysis module pass, I'm running into the following issue: I'm finding my pass queried for results after it has had 'releaseMemory' called on it and its dependencies, but before runOnModule is called again (on my pass or its deps). As you might expect, this makes my pass rather unhappy (and I think correctly so). This happens with LICM
