Hi, Can we find the size of memory a pointer is pointing to in LLVM. For example type *p = (type *)malloc(sizeof(type)*20); then it should give us size as sizeof(type) * 20. -- Sunil Rathee MTech IIT Delhi Not going along with the crowd can help you stand out in the crowd -------------- next part -------------- An HTML attachment was scrubbed...

Hi, Within the basic block I got the instructions and so the operands i got the operands. Can we get the size of the operands. Specifically, if operand is of type structure, Can we get size of this operand? -- Sunil Rathee MTech IIT Delhi Not going along with the crowd can help you stand out in the crowd -------------- next part -------------- An HTML attachment was scrubbed...

Hi all, How Can I get the Loops around an Instruction? I know I can get the basic block of an instruction using inst.getParent() which returns a BasicBlock*. Now I want to use the getLoopFor(BasicBlock) method of the class LoopInfo. But I dont know how to get the LoopInfo. BasicBlock* bb = inst.getParent(); (... what should I add here?) Loop* innerloop = LI -> getLoopFor(bb): Thanks.

Hello, I wrote my own pass which needs to do some loop unrolling. I can perform loop unrolling via opt: opt -mem2reg -loops -loop-simplify -loop-rotate -lcssa -loop-unroll -unroll-count=50 mytest.bc -o mytest.bc This command works perfectly. However, what I really want is to produce the **same behavior** but from my own pass (i.e., I don't want to use opt). I wrote a Module pass which

Thanks Devang and John. My pass is actually a loop pass, not a function pass. So, I couldnt override the getAnalysisUsage. I am in a loop pass, I know the outermost loop. Now How can I get the loopInfo from here? I couldn't find helpful methods in the LoopInfo class documents.

Hi All, When I use llvm, I encounter a problem like "unable to schedule pass A required by C" I investigated deeper. It's like: I have three passes, say A, B, C(all are on function level) A would modify IR code. (change instruction order) For pass B, I would use the result of pass A, I use addRequired<B>(), and &getAnalysis<B>(), it works. void

I am using this pass below: Hi, I would propose to first check if the trip count is calculated correctly. I would do this with opt

Hi all, I tried to have a LoopInfo object in a function pass, and add addRequired in getAnalysisUsage, and then use getAnalysis in runOnFunction(). It worked OK. Now I want to have a module pass to traverse the functions, and similarly, I want to have to loop information of the functions. When I did the above in runOnModule, and build the module pass, the following error popped out, and the

Hi, I'm trying to use the function getAnalysis. This is the code I'm using : void getAnalysisUsage(AnalysisUsage &AU) const { AU.addRequired<LoopInfo>(); AU.setPreservesAll(); } virtual bool runOnModule(Module &M) { LoopInfo &LI = getAnalysis<LoopInfo>(); } I get following error when I try to run my pass : opt:
