similar to: [LLVMdev] Hello Pass Problem

Has anyone seen this error before? I'm trying to load a pass that apparently isn't registered, it's just the "Hello World" sample , so I don't see the problem. Error: me at here:~/llvm/llvm_core/llvm-2.9$ opt -load Release/lib/LLVMHello.so -hello <cdfg.c> /dev/null Error opening 'Release/lib/LLVMHello.so': Release/lib/LLVMHello.so: undefined symbol:

Hi, You might want to try running -loops -loop-simplify before loop unroll. >From loop simplify.cpp This pass performs several transformations to transform natural loops into a00011 // simpler form, which makes subsequent analyses and transformations simpler and00012 // more effective.

Even after all the sequence of commands below bit-code is not showing any effect of loop-unrolling *manish at manish:~/Test2$ llvm-gcc-4.2 -O2 -emit-llvm Hello.c -c -o Hello.bc* *manish at manish:~/Test2$ opt-2.8 -loops Hello.bc -o Hello1.bc* *manish at manish:~/Test2$ opt-2.8 -loopsimplify Hello1.bc -o Hello2.bc* *manish at manish:~/Test2$ opt-2.8 -indvars Hello2.bc -o Hello3.bc* *manish at

1. You should run the passes in the same opt command, for passes like loops which is an analysis pass provides results to the following passes. 2. You can pass a -debug flag to opt to see the some debugging info. 3. I tried this opt -mem2reg -loops -loopsimplify -loop-unroll -unroll-count=3 -debug loop.o -o tt.bc and got this message. Loop Size = 14 Can't unroll; loop not terminated by

You mean like *llvm-gcc-4.2 -O2 -emit-llvm Hello.c -c -o Hello.bc* But still i am not able to observe any effect on bit code by running *opt-2.8 -loop-unroll Hello.bc -o Hello_unroll.bc* On Tue, May 3, 2011 at 3:58 AM, Zakk <zakk0610 at gmail.com> wrote: > Hi, you need to run some optimization passes first.

I just want to try loop-unroll and see corresponding changes in the bitcode file. For that any loop will do. Have you been able to test llvm loop-unroll successfully?

And this brings back CommandLine Error: Arugment blah defined more than once! And without this, opt -load .../LLVMHello.dylib -hello does not work on Darwin because dyld is not able to find SlowerOperationInformer ;) thoughts ? - Devang On Apr 13, 2007, at 11:28 AM, Devang Patel wrote: > > > Changes in directory llvm/lib/Transforms/Hello: > > Makefile updated: 1.7 ->

Hello, I am trying to compile the Hello Project of the lib/Transforms/Hello subdirectory according to the instructions given on http://llvm.cs.uiuc.edu/docs/WritingAnLLVMPass.html document. I am using 1.6cvs source to compile LLVM. The problem is that after running the Make file on the project, the Debug subdirectory contains .lo file in place of .so file. I need the .so file to use with opt

Hi, I am following the instructions on Writing an LLVM Pass on Darwin(8.7.0) powerpc. The loadable library is built. But "opt -load " gives error saying "Symbol not found". I am using LLVM 1.8. Could someone tell me how to fix it? I have tried the same procedure on Pentium4 Redhat9. Everything is ok there. So I think there must be some specific problem on Darwin that I should

Hi, what's the current state of being able to build simple analysis passes out-of-tree against only llvm headers and libraries with llvm-config? I see that clang and klee do not use llvm-config but for example rubinius does. Should both approaches be documented? Currently for example docs/WritingAnLLVMPass.html says "you need to create a new directory somewhere in the LLVM source

I recently had a problem creating LLVMHello. I used this CMake file #!/bin/sh # clangcmake.sh cmake -G "Eclipse CDT4 - Unix Makefiles" -DLLVM_TARGETS_TO_BUILD="X86" -DCMAKE_EXPORT_COMPILE_COMMANDS=ON -DCMAKE_BUILD_TYPE="Debug" -DCMAKE_ECLIPSE_VERSION=4.5 -DCMAKE_CXX_COMPILER=clang++ -DCMAKE_C_COMPILER=clang ../llvm then I ran make LLVMHello and the build failed

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

Owen, I have an issue about the Hello on windows. Please seek "RFC: change build order (or location) of LLVMHello plugin" in this list, thank you :) My proposal: move it onto a new directory plugins/ ps. I would like to know why the Hello plugin is on lib/Transforms. Is it a historical reason? ...Takumi 2010/10/7 Owen Anderson <resistor at mac.com>: > Hey, > > Does

Hi, There is reported bug about this (#2771), or at least related. http://llvm.org/bugs/show_bug.cgi?id=2771 Though it seems there is no "proper" solution known so far. The workaround is to use 'opt' from the Release/bin directory In your case: ../Release/bin/opt -load ../Release/lib/LLVMHello.dylib -hello Would probably work. Best regards Vlado > Hello guys, > >
