--- Comment #2 from Martin Liška <marxin at gcc dot gnu.org> ---
Working on that, it's fixed on master, so bisecting now.

Reduced test-case:

int DMA_List_CheckNodesBaseAddresses_pNode1,
    DMA_List_CheckNodesBaseAddresses_pNode2;
int DMA_List_CheckNodesBaseAddresses() {
  unsigned temp = ((int)&DMA_List_CheckNodesBaseAddresses_pNode1 |
                   (int)&DMA_List_CheckNodesBaseAddresses_pNode2) &
                  65535 << 16;
  int ref = (int)&DMA_List_CheckNodesBaseAddresses_pNode1;
  if (temp != (ref & 65535 << 16))
    return 1;
}

$ arm-suse-linux-gnueabi-gcc-11 pr108340.i -c -O2
