While learning to write LLVM passes and following the precise instructions under http://llvm.org/docs/WritingAnLLVMPass.html, <http://llvm.org/docs/WritingAnLLVMPass.html> I got this error when loading the hello pass to run the test program: opt -load ./Release/lib/Hello.so -hello < test/test.bc > /dev/null Error opening './Release/lib/Hello.so': ./Release/lib/Hello.so:

Hi, I'm writing my first hello world Pass with the class name First, but when I tried to load it using opt, I got the following error: /var/soft/llvm-2.2-build/lib/Transforms/Hello$ opt -load ../../../Debug/lib/First.so --help opt: /var/soft/llvm-2.2/lib/VMCore/Pass.cpp:157: void<unnamed>::PassRegistrar::RegisterPass(llvm::PassInfo&): Assertion `Inserted && "Pass

Hey Chuck, I'm afraid I can't reproduce your error but...a problem you may run into later is that opt will complain with opt: llvm/lib/VMCore/Pass.cpp:149: void<unnamed>::PassRegistrar::RegisterPass(const llvm::PassInfo&): Assertion `Inserted && "Pass registered multiple times!"' failed. Aborted I "fixed" this by replacing the LLVMLIBS line in

It turned out to be the problem of this line in Makefile LLVMLIBS = LLVMCore.a LLVMSupport.a LLVMSystem.a The error is gone when I remove the above line. However, the pass output only contains one line of the main function. First: main It does not have puts and __main as shown in this page: http://llvm.org/docs/WritingAnLLVMPass.html#running So I guess the drived FunctionPass only works on

Thanks, Shu, I guess I haven't updated since my post went out. There are actually 2 problems: 1. mis-compilation: My LLVM-2.5 turned out to be mis-compiled using gcc-4.4.0 (surprise to me) on Debian4-32b. I tried a few different compilers, and gcc-4.0.4 (a relatively old one, again surprised me) seems to work out fine. Question: is there a good/quick/reliable way to figure out whether a

Hi!! It's me again. I guess that there is a problem in the Makefile of my source code. But I don't know where. Could you please verify it? The Makefile is written like this: # Makefile for Genetic Algorithm Pass CXXFLAGS = -Wall -I/iss/fpga3/nicole/galib247/ LDFLAGS= -L/iss/fpga3/nicole/galib247/ga/ -lga -Wl,-E # Path to top level of LLVM heirarchy LEVEL=../../../ # Name of the

Hi all I'm writing a pass for the llc tool. If I try to load my pass(llc -load ../mypass.so), this error message appears : Error opening '/nfs/wsi/ti/graumann/llvm-2.5/Release/lib/LLVMMicha.so': /nfs/wsi/ti/graumann/llvm-2.5/Release/lib/LLVMMicha.so: undefined symbol: _ZTVN12_GLOBAL__N_119MyRegisterAllocatorE -load request ignored. Is this code wrong for the pass

Hello, Following the tutorial for writing a pass, I found the next problem. ***************************** :~/llvm/test$ opt -load ../llvm/Debug/lib/mypass.so -mypass < hello.bc > /dev/null opt: Pass.cpp:151: void<unnamed>::PassRegistrar::RegisterPass(const llvm::PassInfo&): Assertion `Inserted && "Pass registered multiple times!"' failed.

I am using llvm 1.8 and have patched ltdl.c and ltdl.h to the latest version. My Makefile has LLVMLIBS = LLVMCore.a LLVMSupport.a LLVMSystem.a included. > Try using 'nm -m' on the 'opt' executable itself.

I built llvm-2.7 from source on FreeBSD-i386 with: ./configure --prefix=/opt && gmake It builds fine, but the Hello plugin fails to load with an unresolved symbol. $ opt -load /opt/lib/libLLVMHello.so -help Error opening '/opt/lib/libLLVMHello.so': /opt/lib/libLLVMHello.so: Undefined symbol "_ZNK4llvm4Pass5printERNS_11raw_ostreamEPKNS_6ModuleE" -load

Did you try changing the name from Hello to MyHello or something like that? I seem to remember having a similar problem. My tutorial code names the struct MyHello and then registers it as follows: RegisterPass<MyHello> X("myhello", "My Hello World Pass"); You will likely need to change the Makefile as well.

Hello all, Still, is it impossible to use the external llvm custom pass on windows? I can build the 'mypass.dll' on windows using LLVM libraries. And, I use these 2 way to use my pass. clang.exe -Xclang -load -Xclang mypass.dll -c test.c opt.exe -load -Xclang mypass.dll -mypass test.bc -o optimized_test.bc But, Clang and opt didn't working well with my pass. This mean, my pass

Hi, I'm looking for some pointers on how to troubleshoot this problem. I'm trying to write a backend for the AVR. There is an undefined reference at line 48 which is the line FrameInfo() is on. I've tried to use the MSP430 and other targets as references so I'm not sure what changes I did would cause a problem on this line? AVRTargetMachine::AVRTargetMachine(const Target &T,

Thank you, Reid. I have applied tha patch to ltdl.c ltdl.h. The problem still exists. I looked up the symbol on libLLVMCore.a, and found three U-entries and one T-entry. However, the Darwin linker is not able to find the T-entry. Any idea? pollux:~/test jingyu$ opt -load /Users/jingyu/tools/build-ppc/Release/lib/LLVMHello.so -help Error opening

Hi, My pass compiles fine with Gmake,but when i run it with 'opt' it was initially breaking with the following error message : "Error opening '../../../Release/lib/ReusePass.so': ../../../Release/lib/ReusePass.so: undefined symbol: _ZNK4llvm4Pass5printERSoPKNS_6ModuleE -load request ignored. opt: Unknown command line argument '-ReusePass'." Then i

Hi I have written a pass which creates some scheduling information. Its called MParSchedule. This pass works with opt. But when feeding it my experimental backend it seems to loose instructions and fails to work. I am loading this stuff as .so libraries under linux and i am using the amd64 version with a self compiled llvm-gcc. With this call it works: opt

I am trying to write a MachineFunction pass and build it as a loadable module. I want the pass to run after prolog/epilog emmiter. So far, I have been using MachineFunctionPass, but by inserting it to lib/Codegen and hacking the LLVMTargetMachine file, and Pass.h files. I have created a directory "lib/Transforms/MyPass", and inside I have the code of the pass (which is just a
