1) Disable SampleApp. Seems like it's totally horked? SkOSFile_iOS.mm is missing about half the functions needed, and SkOSFile_stdio.cpp is double-providing the others.
2) Drop armv6.
3) Switch from putting headers in sources to putting the corresponding directories in includes.
4) Force cast the type of glShaderSource. Something to do with GR_GL_USE_NEW_SHADER_SOURCE_SIGNATURE?
After all this,
env CC=clang CXX=clang++ GYP_DEFINES=skia_os=ios make

Aarch64 support
This change contains the necessary modifications to have Skia build and
run properly on an ARMv8 processor in aarch64 execution state.
Here's a list of the changes:
- add an arm64 target to the build system + SK_CPU_ARM64 flag
- MatrixTest was failing when built in Release mode. Fused MAC
instructions were generated which made some intermediate results
more accurate. As the test relies on result comparison, the more
precise results when compared to others led to a gap bigger than
what was tolerated. As I don't know if some actual skia code relies
on results being comparable, I've disabled fused MAC instruction
with -ffp-contract=off for arm64.
- Modify include/core/SkOnce.h to have barriers work.
- SK_CPU_ARM64 implies SK_ARM_NEON_MODE_ALWAYS.
- use existing Xfermode optimisations with modifications that can be
removed in the future when toolchains are ready. Also save a few
instructions is two Xfermodes (will apply to ARM too).
- use existing SkBoxBlur and SkMorphology optimisations.
- use existing SkBlitMask optimisations
- use existing BitmapProcState and Convolution optimisations.
Future changes will include:
- Blitters (only partialy merged upstream)
- SkUtils (there's little value in sending asm optimisations without
having them benchmarked on real hardware).

Turn off SK_DEBUG and SK_DEVELOPER when building for the framework.
This allows the framework to create a single makefile which can be
modified to add SK_DEBUG and SK_DEVELOPER as desired.
gyp/common_variables.gypi:

gyp/core.gyp:
Don't depend on cpufeatures, and add the cutils library for

for the framework.
Also reorder image decoders to match the Android order, leaving our
most commonly used ones last (and therefore first in the chain for
trying them).
gyp/libwebp.gyp:
Use the system webp when building for the Android framework. Specify
the correct settings for the framework.
gyp/opts.gyp:
Specify a default set of files to compile when there are no possible
optimizations.
gyp/pdf.gyp:
Add dependencies for Android framework.

This change removes sk_stdint.h since it is only needed for vs2008 and earlier.
This change removes SK_MMAP_SUPPORT define since it is no longer used.
This change removes the stdio.h include from SkTypes.h since on many systems
this is a very large header, few Skia files actually use it, it is
available everywhere standard, and SkDebugf should be used instead.
After this change there is no need for external users to put Skia's
include/config into their own list of includes, saving the headache
of having two header files of the same name and sometimes getting the
wrong one depending on include order.

I left the dummy value in the flattened paint. I'm hoping to do an overhaul of

so it can all go together. If that doesn't pan out we can remove this on its

Most of these issues were due to functions whose definitions appear in header files; I changed those functions to be 'static inline' instead of just 'static' or 'inline', which kills the warning for such functions.
Other functions that were static or anonymous-namespaced but were unused in cpp files were probably called at some point but are no longer; someone who knows more than I do should probably scrub all the functions I either deleted or #if 0'ed out and make sure that the right thing is happening here.
Lots of unused variables removed, and one nasty const issue handled.
There remains a single warning in thirdparty/externals/cityhash/src/city.cc on line 146 related to a signed/unsigned mismatch. I don't know if we have control over this library so I didn't fix this one, but perhaps someone could do something about that one.

Certain compilers in an effort to optimize code chop off files that are never
used. By adding a flag to common conditions and variables we can force skia to
recompile with global static initializers off. By making a call to
SkGraphics::Init we now register all those functions that had been previously
automatically excluded by the compiler.

This patch adds minimal support for dynamic ARM NEON support,
i.e. the ability to probe the CPU at runtime for NEON and
provide alternate code paths when it is available.
- Add include/core/SkUtilsArm.h, which declares a few helper
macros (e.g. SK_NEON_ARM_IS_DYNAMIC), plus the handy
function 'sk_cpu_arm_has_neon()' which returns true if
the target CPU supports the ARM NEON instruction set.
Note that the header is in include/core/ because it will
have to be included from NEON-specific code under src/code/
It would probably be more logical to put it under include/opts/
instead, but this would require moving all the NEON-specific
stuff under src/code/ into src/opts/, which is not trivial
due to the way the code is currently architected.
- Add src/core/SkUtilsArm.cpp which implements
'sk_cpu_arm_has_neon' for ARM-based Linux systems, only
when SK_NEON_ARM_IS_DYNAMIC is true.
(For other cases, 'sk_cpu_arm_has_neon' is an inline function
that returns a constant 'true' or 'false' value).
There is no user-level accessible CPUID instruction on ARM,
so do all CPU feature probing by parsing /proc/cpuinfo.
This is Linux-specific.
For Debug build types, the CPU probing result is printed
to the Android log (or Linux command-line) for easier
debugging.
- Create a new 'opts_neon' target (static library) which shall
contain all the NEON-specific code paths for the library.
This is necessary because -mfpu=neon impacts also non-scalar
code. Just like with -mssse3 on x86, we can't build the rest
of the library with this flag.
Note that for now, we only include memset16_neon and
memset32_neon in this library.
- Modify opts_check_arm.cpp to implement SK_ARM_NEON_IS_DYNAMIC
properly.
Compared to a 'xoom' build, the only difference is the use of
NEON-optimized memset16/32 functions. Later patches will move
more NEON-specific code paths to 'opts_neon'.

This patch removes static initializers related to static and
global mutexes from the final library's machine code when
building on a pthread-capable system.
We use PTHREAD_MUTEX_INITIALIZER to perform POD-style
initialization. You need a line like the following to declare
a global mutex with it:
SkBaseMutex gMutex = { PTHREAD_MUTEX_INITIALIZER };
We introduce the SK_DECLARE_STATIC_MUTEX and SK_DECLARE_GLOBAL_MUTEX
macros to be able to declare static/global mutexes in the source tree
uniformly.
SkMutex is now defined as a sub-class of SkBaseMutex, with standard
construction/destruction semantics. This is useful if the mutex
object is a member of another C++ class, or allocated dynamically.
We also modify a few places to refer to SkBaseMutex instead of a
SkMutex, where it makes sense. Generally speaking, client code
should hold and use pointers to SkBaseMutex whenever they can
now.
We defined a new built-time macro named SK_USE_POSIX_THREADS
to indicate that we're using a pthread-based SkThread.h
interface. The macro will also be used in future patches
to implement other helper thread synchronization classes.
Finally, we inline the acquire() and release() functions in the
case of Posix to improve performance a bit.
Running: 'bench -repeat 10 -match mutex' on an Android device or
a 2.4GHz Xeon Linux desktop shows the following improvements:
Before After
Galaxy Nexus 1.64 1.45
Nexus S 1.47 1.16
Xoom 1.86 1.66
Xeon 0.36 0.31
This removes 5 static mutex initializers from the library
