Hi chenwj,

Thanks for the report. Yeah, it's probably best to track down what's
happening with clang. Could you investigate this further?

Hi Bill,

  Here is the summary of Clang failures (part of).

    Clang :: CXX/conv/conv.prom/p2.cpp

     chandlerc doubts the test itself is fulfill the C++ standard. Although
     "-fshort-wchar" makes the error disappered, chandlerc think
it's not
     the correct solution. Perhaps it's test bug not clang's.

    Clang :: CXX/special/class.copy/p15-inclass.cpp
    Clang :: CodeGenCXX/compound-literals.cpp
    Clang :: CodeGenCXX/copy-constructor-elim-2.cpp
    Clang :: CodeGenCXX/cxx0x-initializer-references.cpp
    Clang :: CodeGenCXX/cxx0x-initializer-stdinitializerlist-startend.cpp
    Clang :: CodeGenCXX/virt-call-offsets.cpp
    Clang :: CodeGenCXX/x86-64-abi-sret-vs-2word-struct-param.cpp

     Use "-triple x86_64-none-linux-gnu" makes above failures
disappered.
    But chandlerc think tests under CXX/ should be platform independent.
    Either move p15-inclass.cpp to CodeGenCXX/ , or make
"linkonce_odr"
    optional in FileCheck so it's not platform dependent.
    
    Clang :: CodeGenCXX/cxx0x-initializer-stdinitializerlist.cpp

     Seems to be difference between ARM and Intel C++ ABI, but I leave it to
     James to comment.

  For whom might be interested in the ARM regression test result, please see
[1].

      Use "-triple x86_64-none-linux-gnu" makes this test pass.
