similar to: [LLVMdev] Writing a pass for the opt tool: likely documentation bug

Sarah, We have Hello pass in svn at lib/Transforms/Hello This is a working example. I will update documentation to include "char Hello::ID = 0".

It can also happen if you link *anything* from LLVM into the Hello.so. Don't do that :) Reid.

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:

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.

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

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

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.

Hi , I get the following error when I try and load a certain pass I have made. Can anyone help me out? What could be the problem? And how can I remove it? opt: Pass.cpp:147: void<unnamed>::PassRegistrar::RegisterPass(llvm::PassInfo&): Assertion `Inserted && "Pass registered multiple times!"' failed. Aborted (core dumped) Thanks Nipun --------------

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, my name is Marc. I wrote a llvm function pass by using the "hello world" tutorial. But this selfwritten pass (GA_VHDL_Pass) dependes on another function pass (GenomePass). GenomePass also dependes on two other function passes. The Pass GenomePass generates an object, which is used in my GA-VHDL_Pass. When I compile my Make file I always get this error message:

I am trying to run the HELLO LLVM Pass under WinXP/MinGW, by following the precise steps available at http://www.llvm.org/docs/WritingAnLLVMPass.html.

I have just started using llvn and I am running in the following error when trying to run Hello World Pass in the llvm documentation. opt: /usr/local/llvm/src/lib/VMCore/Pass.cpp:158: void <unnamed>::PassRegistrar::RegisterPass(llvm::PassInfo&): Assertion `Inserted && "Pass registered multiple times!"' failed. The problem gets resolved if the Hello.so library is

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

Yes, that would make sense, except I don't see any pointers being passed. The relevant line in lib/Transforms/Hello.cpp is: static RegisterPass<Hello>

Loadable modules (e.g. passes) are not supported on windows.

Hi. I'm trying to implement a module pass which can be dynamically loaded by `opt` (against up-to-date llvm from svn). Despite what the tutorial (http://llvm.org/docs/WritingAnLLVMPass.html) states in my module pass I cannot perform getAnalysis and fetch the function pass result. When trying to do so `opt` fails with the following mesage: [***@*** ***]$ opt -load
