Hi Ambika, Could you check if you have bison and flex installed on your machine?

Hi, I had asked earlier from my another ID about duplicating a basic block, but that server is down for moment. I was given suggestion to use CloneBasicBlock, but when I used it I get an error : While deleting: i32* %a Use still stuck around after Def is destroyed: store i32* %a, i32** %p, align 4 opt: /home/ambika/llvm_3/llvm-2.6/lib/VMCore/Value.cpp:81: virtual llvm::Value::~Value():

Hi, I am a Mtech student at IIT,Bombay and presently studying llvm as a part of my Seminar work.Currently,i am writing a simple pass that would detect function pointer call,use and declarations in the src program. I could detect function pointer calls using the getCalledFunction(). However,i am stuck in identifying function pointer declaration and use. is there a way one can distinguish between

Hi, I am a student at IIT Kanpur. I am working on Path Profiling, i just came with a need to know about the number of static paths in a program(actually in a function) before it's actually get run. As i saw in PathProfiling.c file in llvm\runtime\libprofile they are just storing the path information at run time and dynamically adding entries for the new path. But i need to know the number of

Hello. My goal is to use LLVM with JIT compiler for ARM on Android device. Currently I have successfully built and executed LLVM bitcode with interpreter on Android. Speed is not so great, that is why I want to use JIT. I tried building bitcode on windows with llvm-gcc that is provided on llvm home page. Resulting bitcode runs great in interpreter, but it doesn't use JIT. From what I

Forgot to mention. I don't know how well the canadian cross compile stuff works in 2.5. We made some improvements in that area for 2.6. If you have trouble with it, I'd suggest trying 2.6 (or even better, ToT svn) and seeing if things are improved there. -Jim On Sep 25, 2009, at 2:04 AM, Martins Mozeiko wrote: > Hello. > > My goal is to use LLVM with JIT compiler for ARM

Hello all, I am trying to build the latest version of llvm-gcc on a x86_64 architecture running a Linux distribution. Using the READM.LLVM I have managed to run ./configure using appropriate options, but when I try to build using make, it shows the following error message after a few seconds: ../../llvm-gcc/gcc/gengtype-lex.l:31:27: fatal error: gengtype-yacc.h: No such file or directory.

I need to add, also you'll need bison+flex.

More bison woes. llvm-2.1 + the patch Chris mentioned builds without bison, but llvm-gcc4 doesn't: /home/emil/ll/llvm-gcc4.0-2.1.source/missing bison -d -o gengtype-yacc.c ../../llvm-gcc4.0-2.1.source/gcc/gengtype-yacc.y WARNING: `bison' missing on your system. You should only need it if you modified a `.y' file. You may need the `Bison' package in order for

You'll need to install the dev packages for gcc 4.2.

Ok. Thank you for your input. New questions :) : - Is the dev package basically the source code of gcc 4.2 ? Isn't it already fully included in llvm-gcc code base ? - How should I include bison+flex when I have installed Do I need to put additional flags to configure script ?

Thanks. It worked for a few more compilation lines. I now get the following linker error: undefined reference to llvm::MemoryBuffer::getNewMemBuffer(unsigned long, llvm::StringRef) I am surprised since the linker compile line already links with a whole bunch of llvm libraries ...

I got this one fixed by rebuilding llvm Debug (oups). I had an old version. I now seem to have a classical message: version GLIBCXX_3.4.14 not found. I am indeed building llvm-gcc using gcc4.5. Is this the problem ? The fix to this problem indicated in README.LLVM does not help .. Thanks Romain On Thu, Aug 12, 2010 at 6:43 PM, Romain Pechayre <rpechayr at gmail.com> wrote: > Thanks.

Hi, Can we find the size of memory a pointer is pointing to in LLVM. For example type *p = (type *)malloc(sizeof(type)*20); then it should give us size as sizeof(type) * 20. -- Sunil Rathee MTech IIT Delhi Not going along with the crowd can help you stand out in the crowd -------------- next part -------------- An HTML attachment was scrubbed...
