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.

Move cpu_xxx functions to qom/cpu.h
This patch moves a few CPU-releated function declarations to

CPUState instead of a CPUOldState.

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.

exec.c: Use a QTAILQ to list CPUs.
This introduces CPUState, a mere typedef to CPUOldState for now,
and changes the way CPUs are listed in QEMU. The goal is to get
closer to upstream, while also allowing really separating CPUState
from CPUArmState in future patches.
+ Move "current_cpu" to a thread-local variable on Linux, just like
upstream. Testing shows this doesn't affect performance.

Simple renaming: CPUOldState -> CPUArchState where relevant.

CPUState soon). For now, both types are identical so this should not

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.

memcheck: fix guest pc <-> host pc mapping on 64 bit arch
Currently -memcheck A and friends do not report guest PCs properly on 64-bit
hosts, because the code assumes host and guest pointer sizes match. As result,
memcheck can't figure out guest PC so it renders functionality virtually
worthless. This fix changes tpc2gpc from target_ulong to uintptr_t. This works
on both 32-bit and 64-bit hosts, as the type represents unsigned integer
matched to pointer on a given architecture.

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.
