Hello Lei Mou,

   I compile source code of LLVM version 3.1, but Openclc cannot built the
source codes those. LLVM version 3.1 show as below for new version after
checkout the head version from LLVM.

  LLVM (http://llvm.org/):
  LLVM version 3.1svn
  DEBUG build with assertions.
  Built Jun  5 2012 (16:09:51).
  Default target: x86_64-unknown-linux-gnu
  Host CPU: corei7

   How should I set flag of building with LLVM before compile Openclc?  See
error below.

$ make
LLVM-CC nvptx--nvidiacl/lib/convert.cl.bc
error: unknown target triple 'nvptx--nvidiacl', please use -triple or -arch
make: *** [nvptx--nvidiacl/lib/convert.cl.bc] Error 1

Thank you,
Chatsiri Rattana
