Summary: Base gcc fails to compile `sys/dev/hyperv/pcib/vmbus_pcib.c` for i386, with the following -Werror warnings: cc1: warnings being treated as errors /usr/src/sys/dev/hyperv/pcib/vmbus_pcib.c: In function 'new_pcichild_device': /usr/src/sys/dev/hyperv/pcib/vmbus_pcib.c:567: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] /usr/src/sys/dev/hyperv/pcib/vmbus_pcib.c: In function 'vmbus_pcib_on_channel_callback': /usr/src/sys/dev/hyperv/pcib/vmbus_pcib.c:940: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] /usr/src/sys/dev/hyperv/pcib/vmbus_pcib.c: In function 'hv_pci_protocol_negotiation': /usr/src/sys/dev/hyperv/pcib/vmbus_pcib.c:1012: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] /usr/src/sys/dev/hyperv/pcib/vmbus_pcib.c: In function 'hv_pci_enter_d0': /usr/src/sys/dev/hyperv/pcib/vmbus_pcib.c:1073: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] /usr/src/sys/dev/hyperv/pcib/vmbus_pcib.c: In function 'hv_send_resources_allocated': /usr/src/sys/dev/hyperv/pcib/vmbus_pcib.c:1125: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] /usr/src/sys/dev/hyperv/pcib/vmbus_pcib.c: In function 'vmbus_pcib_map_msi': /usr/src/sys/dev/hyperv/pcib/vmbus_pcib.c:1730: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] This is because on i386, several casts from `uint64_t` to a pointer reduce the value from 64 bit to 32 bit. For gcc, this can be fixed by an intermediate cast to uintptr_t. Note that I am assuming the incoming values will always fit into 32 bit!
