2017-01-24disas/cris.c: Fix Coverity warning about unchecked NULLPeter Maydell1-1/+1
Coverity (CID 1005689) warns that we don't check that spec_reg_info() returned non-NULL before dereferencing. Add the check, though as the comment notes this is a can't-really-happen case because the earlier constraint matching should have ruled out the "unknown reg" case.

When qemu-doc.txt was added as a new output format in commit f8bab10b4c3f, it was not added to either the list of files to remove in distclean or to the dependency line that forces qemu-options.texi to be built before attempting to build qemu-doc.*. In particular, the missing dependency meant that on some platforms (notably OSX hosts) we would try to build qemu-doc.txt before qemu-options.texi had been fully written out, and then makeinfo would complain about missing cross-reference targets.

2017-01-23hw/core/null-machine: Add the possibility to instantiate a CPU and RAMThomas Huth2-3/+26
Sometimes it is useful to have just a machine with CPU and RAM, without any further hardware in it, e.g. if you just want to do some instruction debugging for TCG with a remote GDB attached to QEMU, or run some embedded code with the "-semihosting" QEMU parameter. qemu-system-m68k already features a "dummy" machine, and xtensa a "sim" machine for exactly this purpose. All target architectures have nowadays also a "none" machine, which would be a perfect match for this, too - but it currently does not allow to add CPU and RAM yet. Thus let's add these possibilities in a generic way to the "none" machine, too, so that we hopefully do not need additional "dummy" machines in the future anymore (and maybe can also get rid of the already existing "dummy"/"sim" machines one day). Note that the default behaviour of the "none" machine is not changed, i.e. no CPU and no RAM is instantiated by default. You have explicitely got to specify the CPU model with "-cpu" and the amount of RAM with "-m" to get these new features.

2017-01-23vl: Ensure the numa_post_machine_init func in the appropriate locationDou Liyang1-2/+3
In the numa_post_machine_init(), we use CPU_FOREACH macro to set all CPUs' namu_node. So, we should make sure that we call it after Qemu has already initialied all the CPUs. As we all know, the CPUs can be created by "-smp"(pc_new_cpu) or "-device"(qdev_device_add) command. But, before the device init, Qemu execute the numa_post_machine_init earlier. It makes the mapping of NUMA nodes and CPUs incorrect. The patch move the numa_post_machine_init func in the appropriate location.

2017-01-23target-hppa: Add nullification frameworkRichard Henderson1-4/+224
The HPPA cpu has a unique form of predicated execution in which almost any instruction can set the PSW[N] (or "nullify") bit, which suppresses execution (and even decoding) of the following instruction. Execution of a nullified insn clears the PSW[N] bit. This adds a generic framework for branching over nullified insns, or for sufficiently simple insns, transforming the writeback of the result to a conditional move. In the process, we want to be able to represent PSW[N] as a TCG condition, which implies management of the related tcg temps. Signed-off-by: Richard Henderson <rth@twiddle.net>
