Bug ID: 120753
Summary: is_device_ptr does not compile with pointers in struct
elements..
Product: gcc
Version: 15.1.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: schulz.benjamin at googlemail dot com
Target Milestone: ---
#include <omp.h>
struct arraystruct
{
int A;
double* t;
};
int main()
{
arraystruct u;
u.t=(double*)omp_target_alloc(sizeof(double)*20,omp_get_default_device());
#pragma omp target is_device_ptr(u.t)
#pragma omp teams distribute
for(size_t i=1;i<20;i++)
{
u.t[i]=20;
}
compile with
-fopenmp -foffload=nvptx-none -fno-stack-protector -std=c++23
fails with

well, I am pretty sure that u.t is a pointer that I've allocated on device...
Gcc appears not to follow the dots...
