similar to: Passing arguments to LTOCodeGenerator

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:

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 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

The configuration we’re mentioning is a 2-stage bootstrap: You need first to build without LTO your own clang, and then use it for the LTO build. — Mehid > On Sep 20, 2016, at 10:17 AM, Michael Kruse <llvmdev at meinersbur.de> wrote: > > I am the author of Polly's/ISL's platform tests and could reproduce > the problem on my system with this error message: > >

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?

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> >

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 all, I was trying to use LTO facility of LLVM to reduce the footprint of Clang itself. I build the ld-gold  and LLVMgold.so as described at [1] and then set the environment as described too. However, had to add the path for plugin manually as Clang was not able pass it to ld automatically. Following is the setting I used before starting to build (small foot Clang. CXX=clang++ -flto

I am trying to build LLVMgold.so on windows. I came across this piece of code which includes “gold” source directory in tools/CMakeLists.txt if( LLVM_ENABLE_PIC ) # TODO: support other systems: if( (CMAKE_SYSTEM_NAME STREQUAL "Linux") OR (CMAKE_SYSTEM_NAME STREQUAL "FreeBSD") ) add_llvm_tool_subdirectory(gold) else() ignore_llvm_tool_subdirectory(gold) endif() else()

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

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
