Thanks. I got it.
For those who are curious, the command line is like
clang -cc1 -cl-std=CL1.2 tmp.cl

You need to set the cl-std value to 1.2. By default its 1.1.

I was trying to compile a simple OpenCL source with clang:
extern int foo(int, int);
I got an error msg:
clang.exe : tmp.cl:1:1: error: OpenCL does not support the 'extern' storage class specifier
OpenCL spec 1.2 says:
The typedef, extern, and static storage-class specifiers are supported.
Is this a bug? Or did I miss anything? Thanks.
