...eated by llc, my linker cannot locate the following functions. I know that these are standard c++ library functions but g++ cannot locate them. Now my question is that where are these functions defined and how can I link them with my object files, and actually what do they do? declare noalias i8* @_Znam(i64) declare noalias i8* @_Znwm(i64) the emitted error messages are as follows: undefined reference to `operator new[](unsigned long)' undefined reference to `operator new(unsigned long)' We are reaching the deadline of the project but I haven't found any solution for this problem....

I'm developing an llvm-based compiler and when I try to generate executable file the following error occurs: ./bin/llvmcode.s:35: undefined reference to `operator new[](unsigned long)' Note that in the generated IR, the function '@_Znam' is called which is located in one of llvm libraries. So, I should have linked the generated assembly file with that library. Here is the code I used to do that: llvm-as ./bin/llvmcode.ll llc ./bin/llvmcode.bc g++ -g ./bin/llvmcode.s \`llvm-config --cppflags --ldflags --libs core jit native\`...

You probably don't want to be linking the output of your compiler with LLVM libraries, they'd be...

...? Does the front-end provide any hint(s) to the middle-end to facilitate to do so? Particularly, can I distinguish the call arising from the new-expression from various calls if I use llvm-g++ as the front-end? PS: Under llvm-g++, a new expression is translate into this function call: call i8* @_Znam(..) Best, Xiaolong

For example, LLVM 3.4 generates very complicated code for the following IR. I am running on a Haswell processor. Is it because there is no alternative AVX/2 instructions for int64? The same thing

Hello, I update my building scripts to build LLVM 4.0 RC1 (with clang, lldb, libc++, libc++abi, lld) on CentOS 6 and I got a lot of undefined symbols during linking LLDB. I'm using clang-3.9 and this configuration: -DLLVM_TARGETS_TO_BUILD="X86" -DCMAKE_BUILD_TYPE=Release -DCMAKE_C_COMPILER=/usr/bin/clang -DCMAKE_CXX_COMPILER=/usr/bin/clang++
