Hello, My partner and I am making a small app needs to access a C++ library from the LLVM 2.5 JIT. We've made sure that there are no classes and have put 'extern "c"' in front of the functions we need to access. In order to make this work, we seem to need to have a bitcode version of libstdc++ so we can avoid writing our own implementations of std::string and std::vector.

Hi all, Is it possible to build the LLVM tools and libraries as bitcode files? I have managed to compile some software to bitcode files by creating a wrapper around llvm-gcc, llvm-g++ and llvm-ld and some hacking. Using binfmt in Linux you can even execute them directly on the command line. The object format becomes transparent. I tried to compile LLVM itself, but things go wrong with the

Thank Duncan, what I actually want, is to implement a simple processor simulator, which can execute LLVM bitcode. So it must deal with the virtual LLVM instruction set. As I compiled a C or C++ program using llvm-gcc or llvm-g++, I have a bitcode file. If a C++ library is used, some functions will be declared inside it, but not defined there (like the @_Znwj). Is it possible to create LLVM IR

Hi, Yes, stlport was a pain to deploy and maintain + it calls normal operator new/delete (there is no way to put them into a separate namespace). Note that in some codebases we build asan/tsan runtimes from source. How the build process will look with that object file mangling? How easy it is to integrate it into a custom build process? Soon I will start integrating tsan into Go language. For

Hi, > thank for your answer. Is there any document/tutorial about linking > bytecode file with libstdc++ avaiable ? first you need to compile the bitcode to assembler using llc. For example: llc bitcode.bc This produces bitcode.s. Turn this into a executable using: llvm-g++ -o bitcode bitcode.s or g++ -o bitcode bitcode.s It doesn't matter which g++ you use here. Using g++

I've read that LLVM can convert from C++ to C code. So I've used it in such a way: I'm Windows-user so I used MinGW. I employed this file as the test: llvm-hello.cpp: #include <iostream> int main(int argc, char* argv[]) { system("pause"); return 0; } result of "llvm-g++ C:\llvm_hello.cpp -o C:\llvm_hellopp.exe" worked just fine. as a result of

Thanks Duncan and Ashok, As Duncan described, "lli -load=libstdc++.dylib ..." works. I, however, encounted an "Illegal instruction" message, while I was trying to interpret a large program. So, does lli have a debug switch for dumping out the details for errors? Using llc is not that simple, and I have not gotten through the compilation process. For instance, "llc -o

Hi All, Did anyone try to compile glibc with llvm-gcc or clang? I tried to configure glibc with CC=llvm-gcc and it failed with this message: ... checking for a BSD-compatible install... /usr/bin//install -c checking whether ln -s works... yes checking for gcc... llvm-gcc checking for suffix of object files... configure: error: cannot compute suffix of object files: cannot compile See

Hi, I've managed to compile it the class down to a native executable. However, the executable runs for a while then spits out: terminate called without an active exception Aborted and dies. The program never gets to the normal output. Here is a stack trace from gdb: #0 0xf3f6baa6 in raise () from /lib/libc.so.6 #1 0xf3f6d3a8 in abort () from /lib/libc.so.6 #2 0xf41918f8 in
