Hi, unfortunately, my build somehow hangs when linking clang binary and my system is in an unusable state. My toolchain is clang-3.8, gold-1.11 and LLVMgold.so from binutils v2.26.1 (both selfmade) and LTO-flag is enabled. My buildsystem uses cmake-3.6.0 and ninja-1.7.1 (both prebuilt). I have 52 last steps left in my 3rd build. My Linux-kernel is v3.13.0-92 from official Ubuntu repositories. On my Ubuntu/precise AMD64 I have ***4GiB RAM and 256MiB S...

Hi everyone, I'm new to LLVM and I'm still trying to learn how to get everything up and running. I'm trying to use llvm-gcc with the gold plugin and it complains that it can't find LLVMgold.so. As a simple test case I wrote a very basic C file: --- main.c --- int main () { return 0; } ------ and compiled it with: $ llvm-gcc -use-gold-plugin main.c llvm-gcc: -use-gold-plugin, but LLVMgold.so not found. The file in question, LLVMgold.so, was successfully compiled into llvm...

bfd linker 2.26 works fine with LLVMgold.so. As I mentioned in a previous email, 2.26 ar and ranlib also works fine as long as LLVMgold.so is put in a path binutils know about : $(bindir)/../lib/bfd-plugins/ David On Sun, Oct 2, 2016 at 3:59 AM, Carsten Mattner <carstenmattner at gmail.com> wrote: > On Sun, Oct 2, 2016 at 6:...

...l error: 'sys/ndir.h' file not found #include <sys/ndir.h> ... fatal error: 'intrin.h' file not found These seem like tests that are expected to fail. ... The interesting test int main() { __builtin_ffs(0); return 0; } fails like this: /usr/bin/ld[...]llvm/bin/../lib/LLVMgold.so: cannot open shared object file: No such file[...] I have two questions here: Is there anything I might have missed when configuring the gcc-built llvm install for it to be incomplete in the linker department? I mean, the system linker is used (not lld) and that via CC=clang is looking for the...

I am trying to build LLVMgold.so on windows.

I tried building it on windows with some CMake changes. But unfortunatelym my clang crashes when it tries to access the LLVMgold (not able to open it). I have CCed Rafeal and Nakamura who might know why gold plugin in not supported on Windows platforms. --Sumanth G > Hi, > > On 14 June 2014 00:26, <sgundapa at codeaurora.org> wrote: >> I am trying to build LLVMgold.so on windows. >> I came acro...

...I fixed error by using different version of ld with LLVM 2.7. I used ld.gold that comes with Ubuntu 10.04.

Hi there, I checked out the latest code from the repository, and wanna use the gold plugin, but I got the following: libLLVMgold.so: could not load plugin library Do you know why this is happening? Also I noticed the name of the library is changed to LLVMgold.so, and I just renamed it to libLLVMgold.so when I copied it. Is this the right thing to do? Thanks, Guoliang

Hi, I am trying to use LLVM LTO. I read http://llvm.org/docs/GoldPlugin.html and have some questions. Could anyone help? 1. Can LLVMgold.so work with BFD LD instead of gold? In the description of changes in binutils 2.20, "* The plugin target has been added to bfd. It can load the same shared objects used by gold and uses them to provide basic support for new file formats.". Does this mean BFD LD after 2.20 can support LLV...
