Do you know what's the problem, Eric?
Thanks a lot!

Hi,
I'm sorry if the question doesn't fit this mailing list. It seems that LLVM
does not have a user support mailing list so I post it here.
We're using the LLVM tool chain as our static analysis infrastructure. So,

The question I want to ask is what's the difference between using the LLVM

Thanks a lot!

[LLVMdev] undefined symbol: lto_codegen_set_cpu
Hi, all,
I'm using LLVM-3.0. I want to use gold plugin, but I got the following
error message:
/home/tianyin/binutils-2.22/bin/ld: error:
/home/tianyin/llvm-3.0/lib/LLVMgold.so: could not load plugin library:
/home/tianyin/llvm-3.0/lib/LLVMgold.so: undefined symbol:
lto_codegen_set_cpu
Could anyone tell me what's the problem?
Thanks a lot!
