similar to: [LLVMdev] dynamic_cast error

Hi all, I wrote code that compiled with llvm 2.8, but now I'm using llvm 2.9 and it doesn't compile anymore: My code looks like this: User *U; ... if (PHINode * phi = dyn_cast<PHINode>(U)) { ... BasicBlock * Pred = phi->getIncomingBlock(I); ... } And when I compile it with clang: Live.cc:130:27: error: member access into

MetaSplit is an anlysis I just finished writing. It doesn't alter anything, all it does is build a set of "program instructions". For some reason even though if I run it with any other combination of passes I've found, anytime I run it with mem2reg I get a seg fault in dyn_cast! Here's output: Starting program: /mounts/zion/disks/0/localhome/pmeredit/llvm/tools/Debug/opt

Hi, I'm trying to run the pool allocation pass through opt, and I'm running into problems. It segfaults frequently; for example, it does this when the input is a simple Hello World program: [simmon12 at apoc testcases]$ opt -load /home/vadve/simmon12/llvm/llvm/projects/llvm-poolalloc/Debug/lib/libLLVMDataStructure.so -load

Hi, when I try to build libprofile with r80670 (both llvm and llvm-gcc) I get this error: make[1]: Entering directory `.../llvm-svn-debug-obj/runtime/libprofile' llvm[1]: Building Debug Bytecode Archive libprofile_rt.bca (internalize) llvm[1]: Installing Debug Shared Library /nfs/a5/astifter/astifter/llvm/llvm-svn-debug-obj/../llvm-svn-debug-install/lib/libprofile_rt.so 0 llvm-ld

Hi, Going ahead, the llvm-ld seems to segfault (build on Linux with llvm-ld v3.0svn build): make[2]: Entering directory `/root/code/vmkit/mmtk/mmtk-j3' llvm[2]: Building Debug+Asserts Bytecode Module MMTKRuntime.bc 0 llvm-ld 0x0884c66e 1 llvm-ld 0x0884c3fb 2 0xb7891400 __kernel_sigreturn + 0 3 llvm-ld 0x083be9e9 llvm::isa_impl<llvm::Constant,

Hi Akshat, Could you give us your configuration? CPU/OS? How did you configure and build llvm and vmkit?

Hi, I tried building again with the latest llvm. I am getting another seg fault: make[2]: Entering directory `/root/code/vmkit/mmtk/java' Buildfile: /root/code/vmkit/mmtk/java/build.xml main: [javac] /root/code/vmkit/mmtk/java/build.xml:4: warning: 'includeantruntime' was not set, defaulting to build.sysclasspath=last; set to false for repeatable builds [javac] Compiling 1

Hi, Here are my build details. OS: Linux scop 2.6.38-gentoo-r6 #1 SMP Sat Jul 9 13:07:18 EST 2011 i686 Intel(R) Core(TM) i5-2415M CPU @ 2.30GHz GenuineIntel GNU/Linux Machine: VirtualBox (32 bit) Configure (VMKit): ./configure --with-llvmsrc=/root/code/llvm --with-llvmobj=~/code/llvm --with-gnu-classpath-libs=/usr/gnu-classpath-0.98/lib/classpath LD=/usr/bin/llvm-ld

I just noticed there was some .h move around in llvm and fixed the includes in vmkit. Maybe you were just removing the failing includes? In any case, I have updated vmkit for llvm trunk. Let me know if updating helps. Nicolas On Fri, Aug 26, 2011 at 12:00 PM, Akshat Gupta <g.akshat at gmail.com> wrote: > Yep, I am compiling with llvm-gcc. Also I removed the LD flag on the >

I am trying to parse LLVM IR from a bit code file. I went through the following steps. hello.cpp #include <iostream> int main() { std::cout << "Hello world!" << "\n"; return 0;} dump.cpp #include <llvm/IR/Module.h>#include <llvm/IRReader/IRReader.h>#include <llvm/IR/LLVMContext.h>#include <llvm/Support/SourceMgr.h> using

Yep, I am compiling with llvm-gcc. Also I removed the LD flag on the configure, it still gives the same segafault.

This error usually shows up when vmkit cannot find the classpath libs and jar. Make sure --with-gnu-classpath-libs points to the directory of .so files are, and that --with-gnu-classpath-glibj points to glibj.zip.

Hi Akshat, Please use version 0.97.2. vmkit does not support 0.98. Also, it should be fine to not compile gtk+ peer.

Dump the IR before newgvn and run through opt -newgvn. It should crash. I'm not familiar with your frontend but you might want to use -mllvm -opt-bisect-limit.

Hi, I just did a reconfigure and rebuild with the latest svn for vmkit code. The code still seg faults but the stack trace seems to have changed. llvm[2]: Building Debug+Asserts mmtk-vmkit.jar all vmjc: JavaRuntimeJIT.cpp:172: uint32 j3VirtualTableLookup(j3::Class*, uint32, uint32*, j3::JavaObject*): Assertion `dmeth->classDef->isInitializing() && "Class not ready in a virtual
