similar to: [LLVMdev] gold plugin example

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 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

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

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 John, Thank you for your advice. LIBS and LDFLAGS work for the configure script, but they gave errors in the make stage for apache and mysql. I used either of the following ones with other flags: - export LIBS="-L/home/sangmin/Dropbox/Falcon/bin/ -ldummy" - export LDFLAGS="-L/home/sangmin/Dropbox/Falcon/bin/ -ldummy" Here are the error messages: Compile error (apache):

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.

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?

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,

Hi all, Following the example from http://llvm.org/docs/GoldPlugin.html#example1 gives the following error on Ubuntu Karmic: /usr/bin/ld: error: a.a: no archive symbol table (run ranlib) /usr/bin/ld: /usr/lib/crt1.o:../sysdeps/i386/elf/start.S:115: error: undefined reference to 'main' /usr/bin/ld: b.o: in function foo1:b.c(.text+0x4): error: undefined reference to 'foo2'

Hi, I need advice in instrumenting programs using liblto and gold plugin. Specifically, I added my pass in tools/lto/LTOCodeGenerator.cpp. My pass inserts functions (myLoad and myStore) for some load and store instructions. The functions exist in a library file. I found that the approach works for the example in the link: http://llvm.org/docs/GoldPlugin.html $ llvm-gcc -flto a.c -c -o a.o $ ar q
