Lots of duplicated code replaced with a couple of tables. We no longer attempt to manually invert the logic operation: the comments now match the code. In the fully general test, constant propagate (1 << (3 - cc)) into (8 >> cc). The new function will be usable by non-branch insns as well. Signed-off-by: NRichard Henderson <rth@twiddle.net>

At the same time, tidy other usages of tcg_gen_deposit_i64. In some cases we can "type cast" rather than extend, and in others we can allow tcg_gen_deposit_i64 itself to optimize the HOST_LONG_BITS==32 case. Signed-off-by: NRichard Henderson <rth@twiddle.net>

The real gdb protocol doesn't split out pc or cc as real registers. Those are pseudos that are extracted as needed from the PSW. Don't modify env->cc_op during read -- that way lies heisenbugs.

The spice_server pointer is a global variable and vm_change_state_handler() therefore does not use its opaque parameter. The vm change state handler is added with a pointer to the spice_server pointer. This is useless and we probably would not want 2 levels of pointers.

pc_fw_add_pflash_drv() ignores qemu_find_file() failure, and happily creates a drive without a medium. When pc_system_flash_init() asks for its size, bdrv_getlength() fails with -ENOMEDIUM, which isn't checked either. It fails relatively cleanly only because -ENOMEDIUM isn't a multiple of 4096: $ qemu-system-x86_64 -S -vnc :0 -bios nonexistant qemu: PC system firmware (pflash) must be a multiple of 0x1000 [Exit 1 ] Fix by handling the qemu_find_file() failure.

The hw/dataplane/vring.c code includes linux/virtio_ring.h. Ensure that we use linux-headers/ instead of the system-wide headers, which may be out-of-date on older distros. This resolves the following build error on Debian 6: CC hw/dataplane/vring.o cc1: warnings being treated as errors hw/dataplane/vring.c: In function 'vring_enable_notification': hw/dataplane/vring.c:71: error: implicit declaration of function 'vring_avail_event' hw/dataplane/vring.c:71: error: nested extern declaration of 'vring_avail_event' hw/dataplane/vring.c:71: error: lvalue required as left operand of assignment Note that we now build dataplane/ for each target instead of only once.

savevm.c suffers from the same problem as some other files. Some years ago savevm.c was created from vl.c, moving some code from there into a separate file. At that time, all includes were just copied from vl.c to savevm.c, without checking which ones are needed and which are not. But actually most of that stuff is _not_ needed. More, some stuff is wrong, for example, *BSD #ifdef'ery around <util.h> vs <libutil.h> - for one, it fails to build on Debian/kFreebsd. Just remove all this. Maybe there's a possibility to clean it up further - like removing <windows.h> (and maybe including winsock.h for htons etc), and maybe it's possible to remove some internal #includes too, but I didn't check this. While at it, remove duplicate #include of qemu/timer.h. Signed-off-by: NMichael Tokarev <mjt@tls.msk.ru> Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

Curses display requires stdin/out to stay on the terminal, so -daemonize makes no sense in this case. Instead of leaving display uninitialized like is done since 995ee2bf, explicitly detect this case earlier and error out. -nographic can actually be used with -daemonize, by redirecting everything to a null device, but the problem is that according to documentation and historical behavour, -nographic redirects guest ports to stdin/out, which, again, makes no sense in case of -daemonize. Since -nographic is a legacy option, don't bother fixing this case (to allow -nographic and -daemonize by redirecting guest ports to null instead of stdin/out in this case), but disallow it completely instead, to stop garbling host terminal. If no display display needed and user wants to use -nographic, the right way to go is to use -serial null -parallel null -monitor none -display none -vga none instead of -nographic. Also prevent the same issue -- it was possible to get garbled host tty after -nographic -daemonize and it is still possible to have it by using -serial stdio -daemonize Fix this by disallowing opening stdio chardev when -daemonize is specified.
