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,

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 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 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

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 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 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

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

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

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 built the binaries from the 3.1 final tag (http://llvm.org/svn/llvm-project/cfe/tags/RELEASE_31/final/ etc) as below: > ../llvm/configure --enable-targets=host-only --prefix=/local/mnt/workspace/ashoknn/crd/neo/llvmsvn/build/bin > make install I notice that I can compile a program using clang as below: > ashoknn at

With `save-temps` as plugin option, I get extra files for the MAIN module (called `a.o`): `a.o.opt.bc` and `a.thinlto.bc`. The `a.thinlto.bc` file contains nothing, only `source_filename = ...` . The `a.o.opt.bc` (this looks like the result after ThinLTO importing and optimization) contains the assembly block that it should not have: ``` module asm "\09.text" module asm

Resending, can somebody please help?

Are you intending to try to link? That error message isn't coming from clang, but from /usr/bin/ld. If you just want the bitcode for the one source file, you need to pass "-c" as well, just like if you want an object file. -Jim On May 16, 2012, at 5:39 PM, Ashok Nalkund <ashoknn at qualcomm.com> wrote: > Resending, can somebody please help? > > On 5/16/2012 2:47 PM,

MY BAD (in caps)...really sorry to have bothered. I was thinking of -S -E options but forgot the -c option. clang -c -emit-llvm test.c lli test.o both work fine :).
