<pre>Clang looses information about address space of function parameters in some
cases. See examples from review:
<a href="https://reviews.llvm.org/D71272#inline-646266">https://reviews.llvm.org/D71272#inline-646266</a>
void myRead(read_only image1d_t);
typedef write_only image1d_t img1d_wo;
kernel void k1(img1d_wo img) {
myRead(img); // expected-error {{passing '__private img1d_wo' (aka '__private
__write_only image1d_t') to parameter of incompatible type '__read_only
image1d_t'}}
}
or
void f_gen(__generic int *arg_gen) {}
void f(){
__constant int *var_sub;
f_gen(var_sub); // expected-error {{passing '__constant int *__private' to
parameter of type '__generic int *' changes address space of pointer}}
}
'__private' is not printed in the second type in both cases.</pre>
