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

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) {

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

Hi, I'm writing a function pass which is dynamically loaded by opt and I need some analysis and passes to be run before my pass: virtual void getAnalysisUsage(AnalysisUsage &AU) const { AU.addRequired<LoopInfo>(); AU.addPreserved<LoopInfo>(); AU.addRequiredID(LoopSimplifyID); AU.addPreservedID(LoopSimplifyID);

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 on

Hi everyone, I have a question that seems simple, but has been confounding me for several hours. I'd like to 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

I think you probably need to pass -O0 to llvm-ld. The link-time optimizations are probably killing your debug info. --Owen On May 5, 2008, at 8:21 PM, Mark Oskin wrote: > Hi everyone again, > > I did discover the following works (see below).

Hi everyone again, I did discover the following works (see below). However, does anyone know of the "proper" way with LLVM? llvm-gcc -g -c -emit-llvm helloworld.c opt -load=mypass.dylib -mypass < helloworld.o > helloworld-mypass.o llc -fast -f -o helloworld.s helloworld-mypass.o as -o helloworld-prime.o gcc -o helloworld helloworld-prime.o gdb helloworld On May 5, 2008, at

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)

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 pass: clang

I have modified the code as follows; now i am using both scopdetection and scopinformation before dependency check but i think link is missing... virtual bool runOnFunction(Function &F) { std::unique_ptr<ScopInfo> Result; std::unique_ptr<ScopDetection> Result2; //polly::ScopDetection pl; auto &LI = getAnalysis<LoopInfoWrapperPass>().getLoopInfo(); auto

I would have thought this would have been possible.

Just re-sending this. Anyone have any suggestions on how to proceed with debugging LLVM produced executables? The problem appears to be register-allocated variables. Global variables and syntax lines do get symbols using the llc / as method I described below. -Mark On May 6, 2008, at 7:36 AM, Mark Oskin wrote: > >> I think you probably need to pass -O0 to llvm-ld.

Doing it this way makes gdb spew out this: warning: Could not find object file "/var/folders/cQ/cQ+L3+RP2RWOpE +8ZNQdPU+++TI/-Tmp-//ccVljWhn.o" - no debug information available for "defs.h" And then no debug symbols are available.

HI Hameeza, what do mean by link is still missing? Currently it is not possible to use polyhedral information from within in-tree LLVM passes. This is because Polly is not currently part of the LLVM tree, and is only linked into the tools as an external project. I.e., you can't depend on Polly passes in an in-tree pass. What you can do, though, is use Polly from an out-of-tree context. If

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 ├── Makefile ├──

i put following line in CMakeLists.txt; add_subdirectory(mypass) then used make -j9 then i used following and run on canonicalize IR $ opt -load lib/LLVMmypass.so -mypass vec-sum.preopt.ll On Mon, Jan 29, 2018 at 9:39 PM, Michael Kruse <llvmdev at meinersbur.de> wrote: > 2018-01-29 10:18 GMT-06:00 hameeza ahmed <hahmed2305 at gmail.com>: > > I tried writing
