similar to: [LLVMdev] LLVM Hello Project generating .lo file in place of .so file.

Hi all, I find all my passes are all broken with LLVM 3.4. Then I tried out the LLVMHello.so specified in the LLVM doc, http://llvm.org/docs/WritingAnLLVMPass.html and it also crashes. It seems all the functions in the pass do work, but LLVM crashes in the doFinalization() step. Does anyone know this problem? Thanks! Tianyin

I just follow the tutorial: http://llvm.org/docs/WritingAnLLVMPass.html Actually it's not only my module, I used the LLVMHello.so (a sample module in the source tree) and get the crash (I didn't do anything :-P). ~t On Tue, Aug 12, 2014 at 12:57 AM, Eric Christopher <echristo at gmail.com> wrote: > Weird, it definitely shouldn't be crashing.

The module is shipped with the source code, so it's from the developers (not me). The path in the source tree is: llvm-3.4.2.src/lib/Transforms/Hello After compiled LLVM *#./configure --prefix=XXX --with-binutils-include=/path-to-binutils-2.24/include --enable-debug-symbols --enable-debug-runtime --enable-assertions --disable-optimized; make; make install* LLVMHello.so is generated at

Hi all I am trying hello pass in llvm. I have compiled and could generate LLVMHello.so but while giving the pass using opt i am getting below mentioned error. Command used: *opt-2.8 -load ../../cse231_project/llvm/llvm-2.9/Debug/lib/LLVMHello.so -hello < hello.bc* Error opening '../../cse231_project/llvm/llvm-2.9/Debug/lib/LLVMHello.so':

no... I guess verifier runs by default and it points to the doFinailization() function :-( ~t On Tue, Aug 12, 2014 at 12:53 AM, Eric Christopher <echristo at gmail.com> wrote: > No idea, I was suggesting to just run the verifier to see if it would > pinpoint what's broken about the module. > > -eric > > On Tue, Aug 12, 2014 at 12:52 AM, Tianyin Xu <tixu at

Oh, you mean opt -disable-verify? Yes, it does eliminate the crashing... Do you know what's the problem, Eric?

Hi, I'm making my way through the WritingAnLLVMPass tutorial and hitting the following issue. $ opt -load ../../../Debug+Asserts/lib/LLVMHello.so -hello < hello.bc > /dev/null opt: symbol lookup error: ../../../Debug+Asserts/lib/LLVMHello.so: undefined symbol: AnnotateHappensAfter nm -g ../../../Debug+Asserts/lib/LLVMHello.so U AnnotateHappensAfter ... $ ldd

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

Hi ! The Hello world pass sources are in llvm/lib/Transform/Hello/* If you compile llvm, the Hello library will be compiled too. It's not installed but it's in build_directory/Debug/lib/LLVMHello.so (or in build_directory/Release/lib/LLVMHello.so) Olivier.

Hi, I am trying to learn LLVM by following this article http://llvm.org/docs/WritingAnLLVMPass.html I checked 2.8 version from svn, built it and now I am trying to run Hello world example as $ opt -load ./Release/lib/LLVMHello.so -analyze but unfortunately it fails: Error opening './Release/lib/LLVMHello.so': ./Release/lib/LLVMHello.so: undefined symbol:

And this brings back CommandLine Error: Arugment blah defined more than once!

Hi Takumi, > Any feedbacks are welcome. > Have fun! This seems to be pretty useful addition to LLVM on windows! And it seems the only painless way to make plugins working, yay! For me the patch looks pretty good. One minor thing: could you please rename SharedDir => SharedLibDir Thanks! -- With best regards, Anton Korobeynikov Faculty of Mathematics and Mechanics, Saint Petersburg

Dear all, I'm new to the LLVM world and I'm trying to run reproduce the hello world example described here http://llvm.org/releases/3.8.1/docs/WritingAnLLVMPass.html. I started with a fresh new llvm-3.8.1 installation based on cmake (running on Linux x86) using the following command: cmake -DCMAKE_INSTALL_PREFIX=/path/to/llvm -DLLVM_TARGETS_TO_BUILD="X86" ../ The build

I'm working though http://llvm.org/docs/WritingAnLLVMPass.html, trying to write a very simple pass. I have followed all the steps mentioned in this document.But as mentioned I'm not getting any file named Hello.so in Debug+Asserts/lib folder(There is a file named LLVMHello.so only). I have also tried to modify Hello.cpp in lib/Transforms/Hello but these changes doesn't reflect

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

Good summer, all! This patch enables ENABLE_SHARED=1 to build DLL based LLVM toolchain. I have checked this on Cygwin-1.5, Cygwin-1.7, mingw(msysgit) and mingw-cross-fedora12. I can separate this patch into some parts; cleanups, adding definitions and adding rules. Any feedbacks are welcome. Have fun! ...Takumi * Pros - reduction of linking time of toolchain. - capability of -load

Hi! I was trying to run an already build LLVM-pass ( the Hello world ) on Visual Studio. I could locate the The Hello world pass sources in llvm/lib/Transform/Hello/*.But when I compiled llvm using the command "cmake -G "Visual Studio 10" ..\llvm" , I couldn't find the LLVMHello.so file in "build_directory/Debug/lib/LLVMHello.so" neither in
