I think this should also check for !IsPointee as it breaks the following example with error: cannot initialize a variable of type 'c_ptr' (aka 'c1 *') with an rvalue of type 'c1 *'.

struct c1 { int x; };
using c_ptr = c1*;

__kernel void test2() {
  c1 x = { 0 };
  c1* y = &x; // okay
  c_ptr z = &x; // fails

I guess it's an oversight from previous reviews, but FileCheck is not called here.

The pattern should probably be:

//CHECK: |-VarDecl {{.*}} foo 'const __global int' constexpr cinit

(i.e. move the {{.*}} before foo).

This check fails for me because inline is "missing" between static and constexpr. Not sure if it makes sense for foo2 to be inline or not, but that's a different story.

  • Exclude pointee from early return in addr space deduction
  • Improved testing: added FileCheck and avoid testing unnecessary bits

@mantognini Good spot! Thanks!
