Duplication of information in configure and rules.mak. Taking
QEMU_CFLAGS and add them to QEMU_CXXFLAGS, now the value of
QEMU_CXXFLAGS is stored in config-host.mak, so there is no need for

The makefile for libvixl was adding flags for QEMU_CXXFLAGS in
QEMU_CFLAGS because of the addition in rules.mak. That was removed, so

promotion rules mean we may promote an unsigned char to a signed

The VIXL code includes some equality comparisons between signed

these, but older versions of gcc such as gcc 4.6.3 do. Since
libvixl is an upstream library, the simplest approach is to
suppress the warnings by applying -Wno-sign-compare to the
relevant files.
(GCC 4.6 is not quite yet irrelevant for us; it is the gcc
shipped with Ubuntu Precise, for example, which is an LTS

Update our copy of libvixl to upstream's 1.12 release.
The major benefit from QEMU's point of view is that some instructions
previously disassembled as "unimplemented (System)" are now displayed
as something more useful. It also fixes some warnings about format
strings that newer w64-mingw32 compilers were emitting.
We didn't have any local changes to libvixl so nothing needed
to be forward-ported.
Although this is a large commit (due to upstream renaming most
of the files), only a few of the files changed in this commit
are not just straight copies of upstream libvixl files:
disas/arm-a64.cc
disas/libvixl/Makefile.objs
disas/libvixl/README
Note that this commit introduces some signed-unsigned comparison
warnings on the old mingw compilers. Those compilers have broken
TLS support anyway so have only ever been much use for compile tests;
anybody still using them should add -Wno-sign-compare to their

The underlying cause of this is an include loop:
bfd.h -> qemu-common.h -> target-arm/cpu.h -> target-arm/cpu-qom.h
-> qom/cpu.h -> bfd.h
which means that if bfd.h is included first then qom/cpu.h doesn't
get the definition of the disassemble_info type that it wanted.
The easiest fix for this is to include qemu-common.h from tci.c
before including disas/bfd.h.

Cris has the complication of variable length instructions and has
a check in place to clamp memory reads in case the disas request
doesn't have enough bytes for the instruction being disas'd. This
breaks down in the case where disassembling for the monitor where
the buffer length is defaulted to 0.
The buffer length should never be zero for a regular target_disas,
so we can safely assume the 0 case is for the monitor in which case
consider the buffer length to be the max for cris instructions.

The setjmp() function doesn't specify whether signal masks are saved and
restored; on Linux they are not, but on BSD (including MacOSX) they are.
We want to have consistent behaviour across platforms, so we should
always use "don't save/restore signal mask" (this is also generally
going to be faster). This also works around a bug in MacOSX where the
signal-restoration on longjmp() affects the signal mask for a completely
different thread, not just the mask for the thread which did the longjmp.
The most visible effect of this was that ctrl-C was ignored on MacOSX
because the CPU thread did a longjmp which resulted in its signal mask
being applied to every thread, so that all threads had SIGINT and SIGTERM
blocked.
The POSIX-sanctioned portable way to do a jump without affecting signal
masks is to siglongjmp() to a sigjmp_buf which was created by calling
sigsetjmp() with a zero savemask parameter, so change all uses of
setjmp()/longjmp() accordingly. [Technically POSIX allows sigsetjmp(buf, 0)
to save the signal mask; however the following siglongjmp() must not
restore the signal mask, so the pair can be effectively considered as
"sigjmp/longjmp which don't touch the mask".]
For Windows we provide a trivial sigsetjmp/siglongjmp in terms of
setjmp/longjmp -- this is OK because no user will ever pass a non-zero
savemask.
The setjmp() uses in tests/tcg/test-i386.c and tests/tcg/linux-test.c
are left untouched because these are self-contained singlethreaded
test programs intended to be run under QEMU's Linux emulation, so they
have neither the portability nor the multithreading issues to deal with.
