similar to: [LLVMdev] a bug for llvm-gcc??

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

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

Try this: $ llvm-gcc -### -x c /dev/null Then look for a line

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,but when I just simply replace lto_codegen_compile(cg, ...) with lto_codegen_write_merged_modules(cg, "/path/to/output.bc") in the gold-plugin.cpp to see if it will generate a correct bc file,the llvm-gcc/llvm-g++ will call the native ld in the linking step,which causes the failture because of that ld can not recognize an object file which contains LLVM's IL. I understand the

Could be. Are you comfortable using gdb? Last time I looked it was working for me.

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

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

2009/9/17 Nan Zhu <zhunansjtu at gmail.com>: > Yes,it's indeedly the correct one,and new ld can also support -plugin > option,I don't know the reason of the trouble, Does ld actually work if you pass libLLVMGold.so to it? 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

For such Makefiles, the above will not work because llvm-gcc runs ld. What you need is a linker that can link LLVM bitcode files together. If that is the case,

Thank you for the reply,but I meant that when we building,we can not use the native tools such ar and as to process the llvm files,we must have the ability to call llvm-ar and llvm-as instead of the native ones. 在 2009-10-17六的 19:35 -0700，Nick Lewycky写道： > zhunan wrote: > > Hi, > > > > I don't think just use gold-plugin even modified is enough for the task > > of

Just set llvm-ld as the default ld . Such as LD = llvm-ld in makefile, if it's not working, then there is no solution 2009/9/15, zhunan <zhunansjtu at gmail.com>: > I truly get the bytecode file for each souce file,but can I use > llvm-link to link them into a whole-program one automatically through > some scripts? > > >> >> Message: 27 >> Date: Tue, 15

We can use the native tools if they understand llvm IL :-) That is what the plugin does. With it installed you can run

Does the directory where you put the gold plugin look like this? $PREFIX/libexec/gcc/x86_64-unknown-linux-gnu/4.2.1/

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,all Recently I met a question when I want to replace gcc with llvm-gcc through configure script(command). For simply,described like that I typed as following 1.zhunan at sjtu:~/workplace/$ ./configure CC=llvm-gcc CFLAGS="-S -emit-llvm" configure will failed when it checks whether C compiler is working 2.zhunan at sjtu:~/workplace/$ ./configure CC=llvm-gcc CFLAGS="-c

Hello, I down loaded "llvm-gcc4.2-2.7-x86_64-linux" and I built Spec2006 with it. It is great and except for one benchmark the rest work fine. I want to build them with LTO now. I followed the directions in " http://llvm.org/docs/GoldPlugin.html" and built ar, nm-new, and ld-new in binutils. I also built libLLVMgold.so. I get the following error: llvm-gcc: -use-gold-plugin,
