0e5ff1bd3073e3847ac8400ba46814878beb8605 04-Jul-2014 David 'Digit' Turner <digit@google.com> 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!

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.

26d285dfa9f482e5b2f6d6df2bcb0eaed06cb1a9 18-Mar-2014 David 'Digit' Turner <digit@google.com> 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.

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).
