Add support for checking whether test case code can compile without warnings, by recompiling each successful test with -Werror. If the -Werror version doesn't pass, we bail out. This gives us the same level of visibility of warnings in test code as --enable-werror provides for the main compile.

For each newly created RAM block, dirty bitmap is reallocated with g_realloc, which doesn't make any promises on initial content of new extra data in returned buffer. In theory, we initialize this new data with cpu_physical_memory_set_dirty_range() call. The problem is, cpu_physical_memory_set_dirty_range() has a side effect of incrementing ram_list.dirty_pages variable, but only for pages which are not already dirty. And page "cleanliness" is determined using the same not yet uninitialized dirty bitmap we've just reallocated. This results in inconsistency between real dirty page number and value in ram_list.dirty_pages variable, which in turn could (and will) result in errors during VM migration. Zero initialize new dirty bitmap bytes to fix this problem. Signed-off-by: NIgor Mitsyanko <i.mitsyanko@samsung.com> Signed-off-by: NBlue Swirl <blauwirbel@gmail.com>

Commit 427a1a2c ("qapi: avoid reserved keywords") modifies qapi.py, which is used by qapi-types.py and other Python scripts. Because Makefile has no dependencies for qapi.py the qapi code generator will not be rerun and the following build error is produced: net/slirp.c: In function ‘net_init_slirp’: net/slirp.c:721:50: error: ‘NetdevUserOptions’ has no member named ‘q_restrict’ Fix this issue by adding the missing qapi.py dependencies.

A command line device probe using just -device "?" gets processed after qemu-kvm initializes the accelerator. If /dev/kvm is not present, the accelerator check will fail (kvm is defaulted to on), which causes libvirt to not be set up to handle qemu guests. Moving the device help handling before the accelerator set up allows the device probe to work in this configuration and libvirt succeeds in setting up for a qemu hypervisor mode.

qemu_rearm_alarm_timer partially duplicates the code in qemu_next_alarm_deadline to figure out if it needs to rearm the timer. If it calls qemu_next_alarm_deadline, it always rearms the timer even if the next deadline is INT64_MAX. This patch simplifies the behavior of qemu_rearm_alarm_timer and removes the duplicated code, always calling qemu_next_alarm_deadline and only rearming the timer if the deadline is less than INT64_MAX.

This change addresses a problem where QEMU incorrectly traps on floating-point MADD group instructions with SIGILL, at least while emulating MIPS32r2 processors. These instructions use the COP1X major opcode and include ones like: madd.d $f2,$f4,$f2,$f6 Here's Nathan's original analysis of the problem: "QEMU essentially does: d = find_cpu (cpu_string) // get CPU definition fpu_init (env, d) // initialize fpu state (init FCR0, basically) cpu_reset (env) ...and the cpu_reset call clears all interesting state that fpu_init setup, then proceeds to reinitialize all the CP0 registers...but not FCR0." I have verified this change with system emulation running the GDB test suite for the mips-sde-elf target (o32, big endian, 24Kf CPU emulated), there were 55 progressions and no regressions.
