86b1fb06ee6ef53d8961ce96343ba4aa37518840 21-Mar-2014 David 'Digit' Turner <digit@google.com> 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.

6657678c3d86395084f6a699e73614195f06c445 24-Mar-2014 David 'Digit' Turner <digit@google.com> 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.

actually upgrade TCG to a more recent version.

This patch modifies the helpers for the ARM target to ensure that
the CPUARMState, when needed, is always passed explicitly as the
first parameter, instead of relying on a global register variable.

This patch gets rid of target-*/exec.h headers by moving the corresponding
definitions either inside target-*/op_helper.c, or dyngen-exec.h for the
global register-based 'env' value, which will be removed in future patches.

This brings translate-all.c to a state much closer to upstream.
The major difference is the implementation of multi-level page
tables (for PageDesc and PhysPageDesc entries). This is a preliminary
requirement to handle 64-bit address spaces properly.

e2678e116c8cdb0f36b247a5bd9cfacc849362fc 16-Jan-2014 David 'Digit' Turner <digit@android.com> 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.

5285864985be9077e58e42235af6582dee72e841 03-Jun-2011 David 'Digit' Turner <digit@android.com> 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).

This forces -Wall during the build. Note that this patch doesn't
remove all warnings, but most of the remaining ones are from upstream anyway.

238b4b0ef1a01afa66ef267dae4a96401ad386db 20-Sep-2009 David 'Digit' Turner <digit@google.com> 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.

5d8f37ad78fc66901af50c762029a501561f3b23 14-Sep-2009 David 'Digit' Turner <digit@google.com> 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.
