Title:
hw/remote/mpqemu-link.c:221: bad error checking ?
Status in QEMU:
In Progress
Bug description:
hw/remote/mpqemu-link.c:221:36: warning: logical ‘and’ of mutually
exclusive tests is always false [-Wlogical-op]
Source code is
if (msg->cmd >= MPQEMU_CMD_MAX && msg->cmd < 0) {
return false;
}
Maybe better code:
if (msg->cmd >= MPQEMU_CMD_MAX || msg->cmd < 0) {
return false;
}
It might be useful to switch on gcc compiler flag -Wlogical-op
to see these warnings.
