similar to: [LLVMdev] dump cfg after each pass

You can use to create a dot file of everyfunction for an normal llvm-ir.ll file. opt -dot-cfg llvm-ir.ll If you store the dump in a

This is mostly for Richard, but others may have useful thoughts too. I just took a look at the debian stuff. It's generally looking good (though I haven't actually tried to build the debs).

Hi, I do have a FunctionPass that does change the code. This FunctionPass requires another FunctionPass which performs all the necessary analyses. This AnalysisPass again requires MemoryDependenceAnalysis. The problem is, that I would like MemoryDependenceAnalysis to run on the unaltered module. I do not want to have dependencies to changed code. What is the cleanest way to do this? Sounds

Dear Devang Patel, In response to your comment on bug 1868, how do I get BottomPass to requires Pass2 before Pass1? Is it by reversing the order of the calls to AU.addRequired()? -- John T. -- John T. Criswell jcriswel at bigw.org "It's today!" said Piglet. "My favorite day," said Pooh.

Thanks, John. This sounds reasonable that the analysis group just provides an interface to its implementors (pass). Then I have another question, is it allowed to specify multiple pass in the same analysis group in the command line for opt? If yes, which pass will be used for the call of getAnaysis<AnalysisGroup>()? -Thomson On Mon, Jun 25, 2012 at 10:34 PM, John Criswell <criswell at

Using multiple analysis passes that belong to the same group may

Hello I need some help here please. If we compile source files directly in to native code: $ clang -O3 -lm *.c then the runtime is like following real 0m2.807s user 0m2.784s sys 0m0.012s and If we emit LLVM bytcode and apply optimizations $ clang -O3 -c -emit-llvm *.c $ llvm-link *.o -o comb.ll $ time lli ./comb.ll then the runtime is real 0m2.671s user 0m2.640s sys 0m0.020s But, if I

Hello all, I have written one pass to collect information about specific calls in an llvm IR file and am not trying to reference the results from the first pass in a second pass. What is the correct way to reference an additional custom pass in LLVM?
