<pre>Trying to compile the following test program:
-------------------------------------------------------
kernel void test(__global float4 *out)
{
float4 a = (float4)(1.0f, 2.0f, 3.0f, 4.0f);
float4 v = (float4)(a.s23, a.s01);
*out = v;
}
-------------------------------------------------------
with the following command line (rev 355676):
clang -cc1 -triple spir64-unknown-unknown -finclude-default-header -emit-llvm
-x cl -cl-std=c++ test.cl
leads to the following error:
-------------------------------------------------------
test.cl:5:25: error: cannot initialize a vector element of type 'float' with an
lvalue of type 'float2' (vector of 2 'float' values)
float4 v = (float4)(a.s23, a.s01);
^~~~~
test.cl:5:32: error: cannot initialize a vector element of type 'float' with an
lvalue of type 'float2' (vector of 2 'float' values)
float4 v = (float4)(a.s23, a.s01);
^~~~~
2 errors generated.
