[LLVMdev] llc fails to generate code for arm

[Arvind Ayyangar]

Hi

  Sorry for the late reply..
  I managed to build the latest release of llvm.
Now I get the following error  when I try creating the bitcode file:

llvm-gcc: --emit-llvm is not supported in this configuration.

The configure options were :
 /home/arvind/llvm/llvm-gcc4.2-2.1.source/configure
--prefix=/opt/llvm/ --enable-threads --disable-nls --disable-shared
--enable-languages=c --enable-sjlj-exceptions --program-prefix=llvm-
