Fix emulation.
The previous patch removed the memcheck feature, but a subtle bug
prevented emulation from working correctly. Fix this.

memcheck: Remove feature entirely
This patch removes the memcheck feature from the Android emulator
code base. This is for several reasons:
- Supporting the feature impacts many QEMU-specific emulation files
in subtle ways, that make it difficult to refactor this code to
integrate upstream changes.
- The feature only works for ARM (32-bit), has no unit tests, and
generates massive amounts of false positive messages coming
from the platform.
- Barely anyone uses it.
This feature might make a comeback in the future, but this will be
under a different life-form that will have adapted to the new state
of the code.
+ As a bonus, fix the build!

tcg: Upgrade to upstream version.
This switches the full TCG implementation to the upstream version
from the following upstream commit:
1a8e80d7e82aa385ad887dba5d039e399a18264b
Note that this requires completely reqwriting the softmmu_template.h
declarations to adapt to the new world order where all ld/st helpers
now accepts a CPUArchState* value as their first parameter.
+ This also gets rid of the REGPARM macro, which means that on
i386, parameters are now passed on the stack instead of using
registers. As surprising as it is, this doesn't seem to affect
emulation performance in significant ways when starting the
emulator with -force-32bit, compared to the latest SDK emulator
binary. This may be due to the improved binary translator.
Note that this doesn't switch the emulation to use the new
MemoryRegion API, so there are still a few minor differences
with upstream softmmu_*.h headers.
The target-*/ sources have been minimally modified to accomodate
for the changes, and everything seems to work. However, not that
CONFIG_ANDROID_MEMCHECK_MMU hasn't been tested yet.
+ get rid of obsolete softmmu_outside_jit.c
NOTE: There are two important differences with the upstream sources:
- An '#undef small' in tcg.c used to build the Windows binaries
with mingw32 on Linux.
- The declaration of cc_compute_all and cc_compute_c helpers in
target-i386/helper.h use TCG_CALL_NO_SE instead of
TCG_CALL_NO_SE_RWG. Otherwise, it's impossible to boot
an x86 system image properly.

Introduce CPUState.
This patch splits the definitions previously found in CPUArchState,
to place some of them in a common data structure called CPUState,
to mirror upstream.
Note that upstream also makes CPUState a complete QOM object that
derives from DeviceState / DeviceClass, but this patch doesn't do
that. That's why the target-*/cpu-qom.h files, as well as
include/qom/cpu.h are not the real ones from upstream yet.
Future patches will get rid of CPUOldState, which is currently used
as an alias for CPUArchState, but will be replaced entirely by
CPUState, requiring changing the signature of many functions to
match upstream.
QOM-ification will probably happen after that, but may require
a few more patches due to layering / coupling issues.

tcg: Use hash table + static table for helpers.
This changes the registration of helper functions inside of TCG to:
- Use a GHashTable to store the map from helpers to function names.
- Move the helper registration from targets to tcg.
- Merge tcg_register_helper into tcg_context_init.
Note: this makes TCG more dependent on target helper.h headers, it
adds significant coupling, but so be it.

qemu-common.h: Remove include of cpu.h
The "qemu-common.h" included "cpu.h" when NEED_CPU_H was defined, which
introduced some nasty circular header dependency issues that affect later
patches in this series.
This patch removes the include, and fixes all other sources to include
"cpu.h" as needed instead.
+ Move loader declarations to "hw/loader.h"
+ Move some stuff from "qemu/timer.h" to "exec/cpu-all.h"

Rename CPUState to CPUOldState.
Upstream qemu has split the cpu state into two new data structures:
CPUState -> is used to model the CPU state through the QEMU
object model.
CPUArchState -> actually a macro that aliases CPUArmState,
CPUX86State or CPUMIPSState.
Both were part of the "CPUState" in the current emulator sources.
Previous patches introduced CPUArchState, as a simple alias to the
machine-specific state. This patch renames any use of CPUState in
the current code to CPUOldState, except within target-*/ directories
where it is replaced by CPU${ARCH}State instead.
This will allow bringing the upstream CPUState definition in the
source tree, and slowly migrate everything to the right location.

Cleanup: Remove 100+ compiler warnings.
This is a big cleanup that removes compiler warnings by performing
the following:
- Remove unused functions or variables.
- Change pointer cast to be alias safe using unions.
- Use __attribute__((unused)) on some local variable definitions
when their usage depends on conditional defines that are not
always true when compiling the same source several times.
- Fix a couple array indexing bugs.
There are still a few warnings from the JSON lexer, libjpeg and
the TCG helpers though, but the overall compilation is much cleaner.
BUG=NONE

rename target_phy_addr_t to hwaddr to match upstream.
Upstream got rid of the target_phys_addr_t and replaced it with 'hwaddr',
so do the corresponding rename here. Note that:
- This also renames <exec/targphys.h> to <exec/hwaddr.h>
- Upstream always deins hwaddr as a 64-bit type, while the size of
our own hwaddr is still controlled by TARGET_PHYS_ADDR_BITS, and
will be 32 for now.
A future patch will change the type definition to fully match
upstream, but it is more risky / requires more cleanups. It's
simply cleaner / simpler to put the related work in a separate
patch, given the large number of sources touched by the
current change.

Force emulator to quit if it's built w/o global register variable support
Clang and llvm-gcc don't support global register variable (GRV) crucial
to emulator (where a register is reserved to point to target architecture
state for better code-gen). Clang and llvm-gcc are provided in recent
Xcode to replace the original gcc with GRV support. MacOSX developers
may accidentally install newer Xcode and break emulator.
This CL allows emulator (and the rest of Android tree) to build but forces
emulator to quit if it's built w/o GRV support. Developers build
Android tree with clang or llvm-gcc can still get good system image,
but they have to use emulators built the other way or from SDKs to run it.

target-arm: integrate upstream ARM translator.
The new translator has the following benefits:
- faster emulation of ARMv5TE code (through improved JIT)
- proper support for ARMv7 and NEON
- rebuilding the full-eng platform images for ARMv7-A results
in additionnal speed increases (a.k.a. Thumb-2 rocks!).
Note that, as an interesting side effect, NEON machine code is generally
slower than the equivalent C code it is supposed to replace when run inside
the emulator. This can be explained by the fact that for now the translator
simply translates each NEON instruction into a series of sequential host
instructions (and also requires over-head for packing/unpacking/saturation/
etc...).
This change has been tested by running the "full-eng" platform image
rebuilt for ARMv7-A and Neon and using an appropriate kernel image
(prebuilt/android-arm/kernel/kernel-qemu-armv7). The system could boot
and seems to work perfectly. Not a single issue has been experienced
during testing. On a 2.4 GHz Xeon CPU, the image boots in about 25 seconds
(compared to 40 seconds for a vanilla one without this emulator patch).
Thanks to Peter Maydell at Linaro and ARM with his hard work to make this
happen (first in upstream, and now on Android).
This integration is based on the Meego git repository
(git://gitorious.org/qemu-maemo/qemu.git) using the following hash:
7e2d65b0c95c865b1fa6d3d4948e8e822b9ac2fd
On top of which, the following upstream patch has been applied
(with recommendation from Peter):
b7fa9214d8d4f57992c9acd0ccb125c54a095f00
(We chose this repository because it was the closest to the previous
integrate. We will probably use the Linaro ones for future work on this
part of the emulator).

Fixes for obvious ARMv7 bugs in emulator.
This CL doesn't fix ARMv7 problems in the emulator (emulated system still
crashes, although with these fixes it crashes much later than without them),
however, this CL fixes real bugs related to IT block translations.
In particular, it fixes:
- Wrong ITSTATE calculation on condition that gen_intermediate_code_internal
is called with search_pc parameter set to 1. In the original code ITSTATE was
blindly inherited from the CPU's condexec_bits field, without consideration
that translation could be performed starting from an address that has nothing
to do with the current ITSTATE.

Fix upstream ARM emulation bug that broke singlestep mode.
This fixes a really bad bug in the Thumb/Thumb2 ARM emulation related to
conditional instructions execution. The issue was that the previous
implementation did break badly if a page fault occured during the conditional
instruction's emulation. Giving an example if probably the best way to demonstrate
this. Consider the following two instructions:
itt eq
streq r0,[r4, #0]
These two instructions mean, respectively:
- If the Z flag is set, execute the next instruction. Otherwise ignore it
- Store the value of r0 at the address pointed to by r4
In single-step mode (used when debugging the emulator), each instruction is
separately JIT-ed and executed in a different pass. The 'condexec_bits' field
of the CPU state if used to store flags corresponding to the conditional
execution of up to 4 next instructions.
When the first instruction is executed, it simply sets 'condexec_bits' to a
specific value (4).
When the second instruction is executed, things get slightly bit more funky
because what happened was the following:
- the JIT-ed code started by clearing the 'condexec_bits' right at the
start of its sequence (a comment says "to avoid complications trying to
do it at the end of the block", famous last words...)
- a conditional test, based on the current value of the Z flag was added
to skip over the rest of the instruction sequence
- the store itself is implemented through a call to the __stl_mmu helper
function.
The thing is that __stl_mmu may implement a *page fault* (i.e. when the
address in r4 hasn't been commited to memory yet) which requires a switch
to kernel mode (to populate the page), then going back to the instruction's
execution.
This is done in the current implementation by re-running the JIT-er for the
same instruction, however, since 'condexec_bits' was already cleared to 0,
the new JIT-ed code sequence doesn't have the conditional test to skip over
the store. The conditional instruction has been transformed into a
non-conditional one due to the page fault ! This results in either bad behaviour
or, even a crash in the emulator.
The patch fixes the clearing of condexec_bits to happen as it should, i.e.
only when execution has really cleared it.
This is preliminary work to fix the -trace option.
Also, disable the IO Thread when running the standalone emulator. This makes
debugging much easier since everything happens in a single thread.

Workaround ARMv7 emulation issues.
This patch is used to disable the code generator's liveness analysis pass when we
emulate an ARMv7 CPU. This is required to properly run the dex preoptimization pass
during the build of -user system images.
Also includes:
- a fix for a sad typo in target-arm/translate.c related to NEON instruction emulation
- upstream improvements to the x86 and x86_64 backends to generate better goto branches at runtime
- upstream fixes for 64-bit swap and shift operations in TCG
After this patch is applied, re-enabling the ARMv7 memcpy should allow to run the dex preopt
pass succesfully. Anything else is untested though. WE STILL NEED TO FIX THE CODE GENERATOR.

Fix ARMv7 emulation by disabling CPU alignment exceptions
Disable alignment CPU exceptions to be able to boot an ARMv7 system image.
This is because 4.4.0 emits a machine code sequence that stores an 8-bytes double
on a 4-byte aligned address on the stack in the implementation of cvt() in the C
library (see the disassembly for bionic/libc/stdio/vfprintf.c). It is uncertain
that this is a compiler bug at this point, but the upstream QEMU sources don't have
alignment exceptions enabled for any ARM target anyway.
Also, add a check to force CPU emulation to "cortex-a8" if the kernel file name
ends in "-armv7". This is a poor man's approach to hardware configuration that will
be replaced by a more sophisticated solution in the future. Right now, we just want
to be able to build -user system images with the dex preopt pass running in the
emulator with the minimum amount of fuss.

Merge upstream QEMU 10.0.50 into the Android source tree.
This change integrates many changes from the upstream QEMU sources.
Its main purpose is to enable correct ARMv6 and ARMv7 support to the
Android emulator. Due to the nature of the upstream code base, this
unfortunately also required changes to many other parts of the source.
Note that to ensure easier integrations in the future, some source files
and directories that have heavy Android-specific customization have been
renamed with an -android suffix. The original files are still there for
easier integration tracking, but *never* compiled. For example:
net.c net-android.c
qemu-char.c qemu-char-android.c
slirp/ slirp-android/
etc...
Tested on linux-x86, darwin-x86 and windows host machines.

Fix critical bug with emulator tracing where the basic block addresses were wrong.
One of the calls to trace_add_insn() was missing a parameter and was passing in
garbage. This parameter "is_thumb" is expected to be 0 or 1 and is OR-ed with
the basic block address to distinguish ARM and Thumb instruction blocks.

Added tracing of exceptions to the emulator.
Exceptions used to be traced but that code was deleted during a large merge.
