gcc reports a warning which is usually wrong:

target-ppc/dfp_helper.c: In function ‘dfp_get_digit’:
target-ppc/dfp_helper.c:417:1: warning:
 control reaches end of non-void function [-Wreturn-type]

The compiler shows the warning if assert is not marked with the noreturn
attribute or if the code is compiled with -DNDEBUG.

Using g_assert_not_reached better documents the intention and does not
have these problems.

I don't see why tpm is disabled by default: it doesn't have any

is just going to cause it to bit rot.

Enable it by default, and add a --disable-tpm option.

This script compares the vmstate dumps in JSON format as output by QEMU
with the -dump-vmstate option.

It flags various errors, like version mismatch, sections going away,
size mismatches, etc.

This script is tolerant of a few changes that do not change the on-wire
format, like embedding a few fields within substructs.

The script takes -s/--src and -d/--dest parameters, to which filenames
are given as arguments.

Example:

(in a qemu 2.0 tree):
./x86_64-softmmu/qemu-system-x86_64 -dump-vmstate qemu-2.0.json

(in a qemu 2.2 tree:)
./x86_64-softmmu/qemu-system-x86_64 -dump-vmstate -M pc-i440fx-2.0 \
   qemu-2.2-m2.0.json

./scripts/vmstate-static-checker.py -s qemu-2.0.json -d qemu-2.2-m2.0.json

The script also takes a --reverse parameter to switch the src and dest
jsons.  This is just a shorthand for reversing the src and dest.

The --help parameter shows usage information.

This commit adds a new command, '-dump-vmstate', that takes a filename
as an argument.  When executed, QEMU will dump the vmstate information
for the machine type it's invoked with to the file, and quit.

The JSON-format output can then be used to compare the vmstate info for
different QEMU versions, specifically to test whether live migration
would break due to changes in the vmstate data.

A Python script that compares the output of such JSON dumps is included
in the following commit.

This will let threads other than the I/O thread raise QMP events.

GIOChannel is thread-safe, and send and receive state is usually
well-separated.  The only driver that requires some care is the
pty driver, where some of the state is shared by the read and write
sides.  That state is protected with the chr_write_lock too.
