[LLVMdev] clang looking for gold plugin when used with '-emit-llvm' option

[Ashok Nalkund]

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 ashoknn-vm:/local/mnt/workspace/ashoknn/crd/neo/temp/jit$clang test.c
> ashoknn at ashoknn-vm:/local/mnt/workspace/ashoknn/crd/neo/temp/jit$

  If I try to generate the bitcode only, it gives an error:
> ashoknn at ashoknn-vm:/local/mnt/workspace/ashoknn/crd/neo/temp/jit$clang -emit-llvm test.c
> /usr/bin/ld: /local/mnt/workspace/ashoknn/crd/neo/llvmsvn/build/bin/bin/../lib/LLVMgold.so: error loading plugin
> /usr/bin/ld: /local/mnt/workspace/ashoknn/crd/neo/llvmsvn/build/bin/bin/../lib/LLVMgold.so: error in plugin cleanup (ignored)
> clang: error: linker command failed with exit code 1 (use -v to see invocation)
> ashoknn at ashoknn-vm:/local/mnt/workspace/ashoknn/crd/neo/temp/jit$

I then ran it with -v option and it produces:
> ashoknn at ashoknn-vm:/local/mnt/workspace/ashoknn/crd/neo/temp/jit$clang -emit-llvm test.c -v

Any clues?
