[cfe-dev] OpenCL parsing / type support

[Sumesh Udayakumaran]

On a related topic,  clang does not seem to accept  vector compares - If a <
b where a, b are of vector type. However, the assembly language does allow
result of vector types for compares. So is this unsupported yet ?  Open CL
also allows for comparison of vectors.


thanks
Sumesh
