[cfe-dev] OpenCL vector initialization

[Alberto Magni]

Hi Everybody,

The OpenCL standard allows the initialization of vector literals as follows:

typedef __attribute__ ((ext_vector_type(4))) int int4;
uint4 u = (uint4)(1);  // u will be (1, 1, 1, 1)

refer to section 6.1.6 of the OpenCL manual.

clang instead forbids this kind of initialization:
error: too few elements in vector initialization (expected 4 elements, have 1)

The attached patch tries to solve the problem.
Do you agree with my solution ?

Alberto
