Pedro, do you have commit access? If not, I can commit it for you.

Any reason why the additional test in invalid-kernel-attrs.cl only tests
whether the Z dimension is 0? Would be useful to ensure no regressions occur
that we test each dimension (Perhaps you could just submit additional
testing in a further review though, no need to hold up this patch any longer
- the patch LGTM otherwise!)

Cheers,
-Neil.

LGTM too, but please add a test case to invalid-kernel-attrs.cl.

OpenCL allows us to define the workgroup size used in a kernel in order 
to further optimise the code, specifically to that size. 
The syntax is 
__attribute__((reqd_work_group_size(X, Y, Z))) 

where X, Y and Z are compile-time known integers. 
Currently clang allows any of those to be 0, which would be illegal in 
OpenCL. 

The attached patch adds this validation; it's currently a draft and any 
comments would be welcome. 

(I reported this on bug 19699)
