401e77cfe1 MIPS32r2: Fix Chromium runtime crash
Crash is caused by ldxc1 instruction, which traps when double values are
not aligned on 8-byte boundaries. Problem was tracked to SkChunkAlloc which
produces pointers aligned on 4-byte boundaries leading to misalignment.

This change makes sure that SkChunkAlloc will produce pointers that are
aligned to 8 bytes.

Appropriate tests are added to tests/MemsetTest.cpp

TEST=Build Chromium with Clang and run on MIPS32r2 platform
TEST=./out/Debug/dm --match Memset

e3fa811657 [GN] Add support for disabling opts via SK_BUILD_NO_OPTS define.
When targetting iOS and using gyp to generate the build files, it is not
possible to select files to build depending on the architecture. Due to
that, the skia code was disabling all optimisation when SK_BUILD_FOR_IOS
was defined.

Since it is possible to select the correct optimised version when using
gn, this pessimisation is hurting the build. Introduce a new define to
disable the optimisation SK_BUILD_NO_OPTS. It will be used by Chromium
when building skia for iOS with gyp but not gn.

Define SK_BUILD_NO_OPTS along-side SK_BUILD_FOR_IOS for all files that
look like build configuration (Xcode projects, gyp configuration files,
public.bzl) in order to avoid introducing breakage on those builds.

e721a8e883 flags and hacks to get MSAN bot going
This disables a few tests in DM:
   - one BlurLargeImage GM maybe is really broken
   - FontMgrAndroidParser uses libexpat, which I've not (yet?) built from source,
     so MSAN can't see into it.

This extends some of the MSAN stifling we added around SkImageDecoder_libjpeg to SkCodec, and skips .wbmps, .pngs, and .bmps.  We're only seeing issues in colortables for .png and .bmp.

I think I can probably back out disabling Codec and the RAW image decodes...
they should all be covered by the libjpeg stifles.

1497f9f264 Update SK_IMAGE_VERSION to test RAW
Bump SK_IMAGE_VERSION to test the images in v2 in GoogleStorage, which
includes the images from v1 plus test images for SkRawCodec.

Only define skia_decodes_raw on platforms that support it, rather than
defining it always and checking additional conditions to determine
whether to support raw. Further, define it and SK_CODEC_DECODES_RAW
for all targets, so we can use the compile flag in other targets.

In DM, exclude the raw extensions if SK_CODEC_DECODES_RAW is not defined.

Blacklist raw extensions on NexusPlayer, which was running out of memory
when running them.

cc881dafcb Add sk_careful_memcpy to catch undefined behavior in memcpy.
It's undefined behavior to pass null as src or dst to memcpy, even if len is 0.
This currently triggers -fsanitize=attribute-nonnull warnings, but also can
lead to very unexpected code generation with GCC.

sk_careful_memcpy() checks len first before calling memcpy(),
which prevents that weird undefined situation.

This allows me to mark all sanitizers as no-recover, i.e. make-the-bots-red fatal.

afd7c74972 Remove SK_OFFSETOF from SkTypes, clean up offsetof usage.
The motivation for this was to remove SK_OFFSETOF from SkTypes, but
this CL is mostly about cleaning up our use of offsetof generally.

SK_OFFSETOF is removed to SkTypes and added to the two places it is
actually used (for the non standard behavior of finding the offset of
fields in types which are not standard layout).

Older versions of gcc required POD for offsetof to be used without
warning. Newer versions require the more relaxed standard layout.
Now that we no longer build on older versions of gcc, remove the
old warning suppressions.

PODMatrix is renamed to AggregateMatrix. SkMatrix is already POD
(trivial and standard layout). The PODMatrix name implies that the
POD-ness is needed for the offsetof, but it is actually the aggregate
attribute which is needed for compile time constant initialization.
This makes it more obvious that this can be revisited after we can
rely on constexpr constructors.

This also adds skstd::declval since this allows removal of existing
awkward code which casts a constant to a pointer to find the size of
a field.

No API change, only removes unused macro.

f62833d9c9 Detect MIPS DSP and DSPR2 programattically.
Procedure:

$ platform_tools/android/toolchains/ndk-r10c-mips-darwin_v14/bin/mipsel-linux-android-gcc -dM -E - < /dev/null | sort > vanilla.mips
$ platform_tools/android/toolchains/ndk-r10c-mips-darwin_v14/bin/mipsel-linux-android-gcc -mdsp -dM -E - < /dev/null | sort > dsp.mips
$ platform_tools/android/toolchains/ndk-r10c-mips-darwin_v14/bin/mipsel-linux-android-gcc -mdspr2 -dM -E - < /dev/null | sort > dspr2.mips

$ diff vanilla.mips dsp.mips
239a240,241
> #define __mips_dsp 1
> #define __mips_dsp_rev 1

$ diff vanilla.mips dspr2.mips
239a240,242
> #define __mips_dsp 1
> #define __mips_dsp_rev 2
> #define __mips_dspr2 1

So, defined(__mips_dsp) -> SK_MIPS_HAS_DSP, defined(__mips_dspr2) -> SK_MIPS_HAS_DSPR2.

fae010266f Remove IGNORE_ROT_AA_RECT_OPT flag
It looks like the positive version was added (SHADER_AA_FILL_RECT) but the negative version wasn't removed.

b7069e9c1f Compile with VS2015.
Visual Studio 2015 has additional warnings around noexcept and
disabling exceptions, which can be worked around with the
(undocumented) _HAS_EXCEPTIONS macro.

Visual Studio 2013 and 2015 have roundf in math.h, so use it to
avoid extra work and casts.

We avoid using cmath, as it undefs isfinite on gcc, but Visual Studio
2015 no longer provides overloads of copysign from math.h (which is
actually correct). As a result, use copysignf (which is available in
math.h in 2013 and 2015) directly.
