similar to: [LLVMdev] opt seems to ignore -load (Win32)

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

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

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 currently attempting to implement a pass that will hopefully run under the opt tool. Currently, I'm having some difficulties -- the sample code for the Hello pass (see http://llvm.org/docs/WritingAnLLVMPass.html) doesn't work. The first error is that the section starting 'As a while, the cpp file looks like:' omits the declaration for char Hello::ID = 0 that is

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.

Hello LLVM Folks, I just tried running the example off http://llvm.org/docs/WritingAnLLVMPass.html#quickstart. I used the same code in the example to create a new pass called hello, and tried compiling the same like: The code for pass.cpp: #include "llvm/Pass.h" #include "llvm/Function.h" #include "llvm/Support/raw_ostream.h" using namespace llvm; namespace {

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, I'm a little confused about the 3th and 4th arguments in the registration function, explained here: http://llvm.org/releases/3.3/docs/WritingAnLLVMPass.html e.g static RegisterPass<Hello> X("hello", "Hello World Pass", false /* Only looks at CFG */, false /* Analysis Pass */); "Lastly, we

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

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.

"A module pass can use function level passes (e.g. dominators) using getAnalysis interfacegetAnalysis<DominatorTree>(Function), if the function pass does not require any module passes." http://llvm.org/docs/WritingAnLLVMPass.html In your case, A module pass (ModPass2) is trying tu use function level pass (FunPass1) which uses module level pass (ModPass1).

I have seen INITIALIZE_PASS(LiveVariables, "livevars", "Live Variable Analysis", false, false); in the llvm/lib/codegen/LiveVariables.cpp, where LiveVariables is a subclass of MachineFunctionPass, and #define INITIALIZE_PASS(passName, arg, name, cfg, analysis) \ static RegisterPass<passName> passName ## _info(arg, name, cfg, analysis) in PassSupport.h Is this code used

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

Hello, I'd appreciate it if anyone can tell me what the error message means and point out what I am doing wrong. Thank you. I am trying to use the result of the DominatorTree analysis in my ModulePass class as explained in the section "Writing an LLVM Pass". http://llvm.org/docs/WritingAnLLVMPass.html#interaction I called the method "addRequired<DominatorTree>()"

I am learning to write LLVM pass by trying to reproduce [hello world][1] example. The pass `hello.cpp` looks like: #include "llvm/Pass.h" #include "llvm/IR/Function.h" #include "llvm/Support/raw_ostream.h" using namespace llvm; namespace { struct Hello : public FunctionPass { static char ID; Hello() : FunctionPass(ID) {}

Thanks, John. There were a couple of function declarations in the module, and 'getAnalysis' failed for those. By the way, what do you mean by "in older versions of LLVM"? I'm quite sure I was using the latest llvm trunk. 2011/6/16 John Criswell <criswell at cs.uiuc.edu>: > On 6/15/11 6:46 PM, Alexey Bakhirkin wrote: >> Hi. I'm trying to implement a module

Hi Eli, Thanks for the link! I'm able to compile a standalone pass outside of the source tree, and I'm obviously ably to compile analysis groups inside the source tree. However, the problem comes when I try to do what the tutorial suggests to create an analysis group outside of the source tree. My understanding is that building out of tree requires different methods to register the
