When I build LLVM 2.6 after configuring it with the --with-binutils-include option so it points to the gold plugin src/include directory, I get the errors below. I used "cvs -z 9 -d :pserver:anoncvs at sourceware.org:/cvs/src co src" to check out the gold-plugin, as is documented on llvm.org. -------------------------- make[2]: Entering directory

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.

I am a bit confused by the documentation of the gold plugin (http://llvm.org/docs/GoldPlugin.html). I want to use the gold plugin on my Linux system so I can run "llvm-gcc -use-gold-plugin." In the documentation it talks about building gold with plugin support (which involves running "make gold-all") and building the LLVMgold plugin (which involves configuring LLVM with

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

Dear all, I'm trying to use the gold plugin to make it easier to generate LLVM bitcode from complex applications. I did the steps mentioned on "http://llvm.org/docs/GoldPlugin.html". Both linking and LLVM generation seem to work properly, however when using the tool ar, the symbol table is lost. "no archive symbol table (run ranlib)". I'm using LLVM 2.9, Ubuntu 10.10,

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?

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:

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

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?

Hi all, I tried to build the LLVMgold plugin. Something weird happened. Here is the error message: gold-plugin.cpp:45: error: âld_plugin_set_extra_library_pathâ does not name a type gold-plugin.cpp: In function âld_plugin_status onload(ld_plugin_tv*)â: gold-plugin.cpp:141: error: âLDPT_OUTPUT_NAMEâ was not declared in this scope gold-plugin.cpp:199: error: âLDPT_SET_EXTRA_LIBRARY_PATHâ was

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

Dear community, Recently I discovered that llvm gold linker plugin (LLVMgold.so) doesn't add llvm instrinsics symbols to the linker symbol table. I do not claim that something is necessary wrong, just want to share my observations with the community. Brief summary If I create a static library with a custom version of 'exp()' math function and link it as follows: $

Attached is the start of a patch to make the gold plugin work on Darwin for use as a cross-compiler. There needs to be a build step somewhere in llvm-gcc that copies it into libexec/<gcc poop>/libLLVMgold.so, but I've been doing that manually for now. It doesn't seem that simple use of -O4 results in the plugin learning what subtarget is desired. I presume that the llvm-gcc driver

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.".

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> >
