Hello LLVM, I am following the document "Writing an LLVM Pass". When I ran "opt -load ../../../Debug/lib/MyPass.so -mypass < hello.bc > /dev/null" I got the next error: ***@ubuntu:~/test$ opt -load ../../llvm/Debug/lib/MyPass.so -mypass < hello.bc > /dev/null opt: Pass.cpp:159: void<unnamed>::PassRegistrar::RegisterPass(const llvm::PassInfo&): Assertion `Inserted && "...

Hello, I need to analyze dependencies in my llvm ir by using polly. i created a new pass called mypass there i added polly dependency analysis pass but when i execute this pass in gdb i get no data. Why is that so? My code is follows; namespace { struct mypass : public FunctionPass { static char ID; mypass() : FunctionPass(ID) { } virtual bool runOnFunction(Function &F) { polly::D...

How do you compile the code? Within the Polly subdirectory using CMake? How do you run your pass. Using "opt -mypass inputfile.ll"?

Hi again, I come back to this issue with an example. It's a pass which does nothing but throw the 'Unable to schedule' error. namespace { struct MyPass : public FunctionPass { static char ID; // Pass identification, replacement for typeid MyPass() : FunctionPass(ID) { initializeMyPassPass(*PassRegistry::getPassRegistry()); } virtual void getAnalysisUsage(AnalysisUsage &AU) const { AU.addRequiredID(LoopSimplify...

...quiredID(LCSSAID); AU.addPreservedID(LCSSAID); AU.addRequired<ScalarEvolution>(); AU.addPreserved<ScalarEvolution>(); } When I run it with opt -load, I'm getting the following error: Unable to schedule 'Canonicalize natural loops' required by 'MyPass' Unable to schedule pass After looking at the pass manager framework, it seems that passes with lower level than FunctionPass (such as LoopPass in my particular case) cannot be scheduled on-the-fly or must be handled by specific function managers. This is not the case for module passes, i.e...

Thank You. Actually i pass polly canonaclize IR to my new created polly pass called "mypass". Mypass should first detect scops then find depedndencies as the mechanism conventional approach. Now i know how to write llvm pass here i am writing pass as loadable module first afterwards i will integrate it with opt in the end. I tried writing following code. Could you please help me...

...debug a binary produced with LLVM. For the life of me, I can't get any symbols into gdb and llvm-db won't even start the program nor load any useful information about it. Here's my current strategy (which isn't working): llvm-gcc -g -O0 -c -emit-llvm helloworld.c opt -load=mypass.dylib -mypass < helloworld.o > helloworld-mypass.o llvm-ld -native -o helloworld helloworld-mypass.o gdb helloworld I've tried several variations on the above. Any suggestions? Note, what is critical about the whole thing is I must run "mypass" on the bytecode file. I'...

Hi everyone again, I did discover the following works (see below).

The following code is causing an "UNREACHABLE executed!" and a stack dump, any ideas? namespace { struct myPass : public CallGraphSCCPass { static char ID; myPass() : CallGraphSCCPass(ID) {} virtual void getAnalysisUsage(AnalysisUsage &AU) const { AU.setPreservesAll(); AU.addRequired<LoopInfo>(); } virtual bool runOnSCC(CallGraphSCC &SCC) { for (CallGraphS...

Hello, I have written a pass for the IR and I can run it with opt -load lib/LLVMMyPass.so -mypass -myarguments -S -o output.ll < output.bc I have registered my pass with the following code: static RegisterPass<MyPass> X("mypass", "MyPass Pass (with getAnalysisUsage implemented)"); How do I include the same pass in the clang driver. I tried running the p...

Hi guys, I am writing a LLVM pass plugin, and just simply add a directory mypass into llvm/lib/Transforms. But since I don't hope this directory to contain too many source files, I add some subdirectories. For instance, there are 2 files inside *mypass/sub: basic.h, basic.cpp. Here is the structure of the directory llvm/lib/Transforms/mypass $tree mypass mypass ├──...
