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 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, 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 compiled clang+gold using a gcc under path /s/gcc-4.3.1/bin/. Later on I do configure and make for flex-2.5.35, and the following command is invoked: "/path/to/my/gold/ld" --hash-style=gnu --no-add-needed --eh-frame-hdr -m elf_i386 -dynamic-linker /lib/ld-linux.so.2 -o flex /usr/lib/gcc/i386-redhat-linux/4.1.2/../../../crt1.o

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,all I'm using ubuntu8.04 and I'm installing gold-plugin along with the document of that, After I built the binutils and LLVM with plugin enabling,and I also replace ld with ld-new which supports plugin,I tried to compile a hello world program by this: llvm-gcc -use-gold-plugin a.a b.o -o hello which is similar with the example in the document,it tells me that libLLVMgold.so can not

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

Yes,but ubuntu's directory structure is not exactly the same as the classic linux distribute, I put libLLVMgold.so in /usr/lib/gcc/i486-linux-gnu/4.2.4 where cc1 is also in. Strange situation,is it a bug for llvm-gcc???? 在 2009-09-18五的 12:58 +0300，Török Edwin写道： > On 2009-09-18 03:06, Nan Zhu wrote: > > OMG,that's just my situation... > > > > I can link with

OMG,that's just my situation... I can link with libLLVMgold.so manualy,but will fail in that by llvm-gcc. Debug llvm-gcc????? Any one installed the gold-plugin successfully can give some instruction? 2009/9/18 Rafael Espindola <espindola at google.com> > 2009/9/17 Nan Zhu <zhunansjtu at gmail.com>: > > Yes,it's indeedly the correct one,and new ld can also support

Yes,it's indeedly the correct one,and new ld can also support -plugin option,I don't know the reason of the trouble, 2009/9/17 Rafael Espindola <espindola at google.com> > > llvm-gcc -use-gold-plugin a.a b.o -o hello > > > > which is similar with the example in the document,it tells me that > > libLLVMgold.so can not be found ,but I truly put it in the

That looks correct. Can you check that *) It is the correct cc1 :-) (run llvm-gcc with

Try to link with llvm-gcc without the -use-gold-plugin option and with -v (it will fail as expected). Copy the collect2 line and add the -plugin line. If
