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

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,

The path to libLTO.so in LLVMgold.so points to the build directory on my machine: % ldd /usr/local/lib/LLVMgold.so linux-vdso.so.1 (0x00007fff3d795000) /var/tmp/build_llvm_clang/Release+Asserts/lib/libLTO.so => not found libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f1703983000) ... I have configured clang with: ../llvm/configure --enable-optimized

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?

I didn't try to compile it locally (I don't have/use gold), but you should be able to fix the 3 errors fairly easily (looks like missing includes mostly). -- Mehdi > On May 30, 2016, at 5:11 AM, Shi, Steven <steven.shi at intel.com> wrote: > > Hi Mehdi, > Your patch cannot compile with gold-plugin.cpp in latest trunk either, the failure is same as llvm3.8 as below.

Hi Mehdi, The llvm3.8 gold-plugin.cpp is very different from the latest one on trunk. Your patch has compiling failure on llvm3.8 as below. I will try it on latest trunk later. Thank you help anyway!

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:

With this patch, it seems that it produces a file named LLVMgold.so instead of libLLVMgold.so.

The copy in that directory can have any name you like. BFD will try all. Note that that is the copy that nm and ar will use. The linker (gold) requires you to pass -plugin to it. >> >> Copying it

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

Hi everyone, I want to perform whole-program analysis for apache httpd using httpd's original autoconf system so that I need to generate a single bitcode file. So I follow the instructions in LLVM document on gold plugin http://llvm.org/docs/GoldPlugin.html#lto-how-to-build. However, when running a simple program using LTO, clang fails to link the object file with the LLVM bitcode.
