Executing nm --plugin /usr/lib/bfd-plugins/LLVMgold.so test.a Gives: 00000000 W _ZN6tester4dumpEv 00000000 W _ZN6tester7readArgEPc 00000000 W _ZN6testerC1Ev 00000000 W _ZN6testerD1Ev And and more entries Without the plugin command "File format not recognized". So it seems like nm is using the plugin. Istvan

Hi all, I got an error from the gold plugin example in the following link: http://llvm.org/docs/GoldPlugin.html#example1 Here is the error message: sangmin at sangmin-desktop:/tmp$ llvm-gcc -use-gold-plugin a.a b.o -o main /usr/bin/ld: error: a.a: no archive symbol table (run ranlib) /usr/bin/ld: /usr/lib/crt1.o:(.text+0x18): error: undefined reference to 'main' /usr/bin/ld: b.o: in

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.

Hi, I fixed error by using different version of ld with LLVM 2.7. I used ld.gold that comes with Ubuntu 10.04. Here is the version info: sangmin at sangmin-desktop:/tmp$ ld -v GNU gold (GNU Binutils for Ubuntu 2.20.1-system.20100303) 1.9 My experience of gold plugin is as follows: LLVM 2.7 (with libLLVMgold.so) + ld 2.20.1 (from Ubuntu 10.04) : O LLVM 2.7 (with libLLVMgold.so) + ld 2.21.51

How big is your project? LTO eats RAM even faster than chrome. For example linking clang with LTO could take 16GB of ram. Have you tried using LTO on your project on that machine, or is it your first time?

I have been trying to enable the gold linker on FreeBSD to use the link time optimizations. I made gold from the binutils under /usr/ports. After building binutils using make -k install clean i got ld under /usr/bin and in the directory /usr/local/bin i got ld, ld.gold and ld.bfd. Now while trying to use link time optimization for the simple example programs

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.".

Rafael, Rui, This is obviously an old thread, but in case there is interest, I've been able to get this to work (using the LLVM gold plugin with the ld.bfd linker). This requires some additional logic in the ld.bfd linker (and a small change to the bfd library). I've attached the patch (against binutils HEAD from 2013-09-17) in case anyone finds this useful. The core issue is that ld.bfd

Quick update: the previous patch only worked for static linking; this version should work for both static and dynamic linking. I'm not going to send any more updated patches to this list, but please feel free to e-mail me off-list, and I'll be happy to share any updates I have at any point in the future. -Hal ----- Original Message ----- > Rafael, Rui, > > This is obviously

You should probably send them for review/inclusion in bfd.

the symlink ld is already pointing to /usr/bin/ld. Also -fuse-ld=gold does not works on clang in freebsd. I am not sure where is the problem?should I remove /usr/bin/ld and create a new symlink to /usr/local/bin/ld.gold?

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 6:52 AM, Teresa Johnson <tejohnson at google.com> >

Hi, I've been following the instructions on how to use the LLVM Gold plugin at http://llvm.org/docs/GoldPlugin.html while building an multiple versions of WebKit. The documentation hasn't been updated since 2010 and hasn't really matched my experiences, so I'd like to ask if I'm doing these steps incorrectly. What I'm trying to do is force all compilation steps to
