similar to: [LLVMdev] Compilation error with LLVM 2.9

Hello, Following statement from LLVM Programmer's Manual is not compiling. CallInst* callInst = dyn_cast<CallInst>(&*basic_block_iterator_1); The gcc version is : gcc (GCC) 4.0.2 20051125 (Red Hat 4.0.2-8) ============ Error message ============ llvm/include/llvm/Support/Casting.h: In function 'bool llvm::isa_impl(const From&) [with To = llvm::CallInst, From =

I now understand that IndVarSimplify.cpp is capable of reproducing array references when the pointer initialization from the array address is found inside the immediately enclosing loop, such that in the following code: int A[20000], B[100], Z; int main() { int i, j, *a, *b; for ( a = &A[0], i = 0; i != 200; i++ ) for ( b = &B[0], j = 0; j != 100; j++

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

I think I understood the problem you're trying to solve. I didn't, however, understand the problems you are having (maybe you're not running mem2reg?). I do have a little piece of code that I think does (more or less) what you want. Take a look at it, try understanding it, and see if it helps you out. You might have to change it a bit since you're replacing uses after an

Thanks for the reply. For the source code: int main() { int a = 0; int *p; p = &a; call_arnamoy(p); int *p1; p1 = p; return 1; } The bit code: %retval = alloca i32, align 4 %a = alloca i32, align 4 %p = alloca i32*, align 8 %p1 = alloca i32*, align 8 store i32 0, i32* %retval store i32 0, i32* %a, align 4 store i32* %a, i32** %p, align 8 %0 = load i32** %p, align 8 %call = call i32

Hi folks, Hope this is not a silly question. But it bothers me when I am thinking about it. My question is: 1. In the implementation of serverSplitPHINodes(), why it only checks the first PHI node for possible multiple inputs from outside the region to extract. There could be more than one PHI nodes in the header block, and the code only checks the first one. I don't quite get it.

Hi all, I have encountered the following instruction: %.0.i = phi i8* [ %9, %8 ], [ %11, %10 ] How can I get the %8 and %10? I'm using http://llvm.org/doxygen/classllvm_1_1PHINode.html as a reference but I cannot understand how to do that. Thanks -------------- next part -------------- An HTML attachment was scrubbed...

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

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, 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 >
