The target specfic part is a load from the implicit6// argument buffer to use for the high pointer bits. It's just that buffer won't7// be initialized to something useful. The proper way to diagnose invalid flat8// usage is to forbid flat pointers on unsupported targets.9 10// CHECK-LABEL: @test_is_shared_global(11// CHECK: [[CAST:%[0-9]+]] = addrspacecast ptr addrspace(1) %{{[0-9]+}} to ptr12// CHECK: call i1 @llvm.amdgcn.is.shared(ptr [[CAST]]13int test_is_shared_global(const global int* ptr) {14 return __builtin_amdgcn_is_shared(ptr);15}16 17// CHECK-LABEL: @test_is_private_global(18// CHECK: [[CAST:%[0-9]+]] = addrspacecast ptr addrspace(1) %{{[0-9]+}} to ptr19// CHECK: call i1 @llvm.amdgcn.is.private(ptr [[CAST]]20int test_is_private_global(const global int* ptr) {21 return __builtin_amdgcn_is_private(ptr);22}23
