----------------
It seems like there is something wrong with access qualifiers for images. I
have applied this patch and tried to compile the following code:
```
typedef int int2 __attribute__((ext_vector_type(2)));
typedef float float4 __attribute__((ext_vector_type(4)));
void kernel k(write_only image2d_t image, int2 coord, float4 data) {
write_imagef(image, coord, data);
}
```
I got the following output:
```
clang -cc1 -triple spir /work/tmp/tmp.cl -emit-llvm -o - -fadd-opencl-builtins
/work/tmp/tmp.cl:5:16: error: passing '__write_only image2d_t' to parameter of
incompatible type '__read_only image2d_t'
write_imagef(image, coord, data);
^~~~~
1 error generated.
