[Libclc-dev] Why cannot compile source code libclc when flag define with "'nvptx--nvidiacl', 'nvptx64--nvidiacl'"

[Lei Mou]

Hi Chatsiri,

Sorry, I made a mistake in my previous mail, NVPTX backend is not included
in the 3.1 release. Please checkout llvm from the svn repository, and make
sure the NVPTX backend is enabled in your compiled binary. You should see
something like this when running llc --version:

LLVM (http://llvm.org/):
  LLVM version 3.2svn
  DEBUG build with assertions.
  Built May 31 2012 (20:31:31).
  Default target: i386-pc-linux-gnu
  Host CPU: penryn

  Registered Targets:
    .... Irrelevant backends are ignored .....
    nvptx    - NVIDIA PTX 32-bit
    nvptx64  - NVIDIA PTX 64-bit

Then libclc should work as expected.

Regards,
Lei Mou
