Change-Id: Id6e6781d8da878413c2e57dcae5e2f2841174181
this uses the format introduced to some files in:
cc3577e9 fuzzer/*: use src/ based include paths
Change-Id: I9b5cbeadbb9d54d1e89f474a6e479a5eb3175ed7
(cherry picked from commit c5bc36243a)
after:
ece18e55 dsp.h: respect --disable-sse2/sse4.1/neon
WEBP_USE_* will be set when a module is targeting a particular
instruction set, e.g., sse4.1, and not overridden if WEBP_HAVE_SSE41 is
set, as previously this would ignore the case where the instruction set
was disabled via config.h and the HAVE macro was unset.
dsp.h not ensures WEBP_HAVE_* are set when WEBP_USE_* to cover cases
where the files are built without config.h.

This way target_link_libraries(my_target PUBLIC webp) is enough,
no need to add include directories explicitly for the public headers
such as src/webp/decode.h. This matches the /usr/include/webp/decode.h
installation folder path prefix (#include "webp/decode.h").
See https://bugs.chromium.org/p/webp/issues/detail?id=532
The target_include_directories() calls for cwebp, dwebp etc. may be
unnecessary now and may be removed in another patch.
Change-Id: I2c85218920ffc35ebec23e0dd239f71e29add23b
previously this would be overridden if the instruction set was enabled
via -msse4.1, __aarch64__, etc.
Change-Id: I51e87a7da7589c6093d260b848ab41d89ec7b990
the container check may not be strictly necessary now that the alpha
check has matured and the library will detect usable alpha, but it's
safer to fix this case first before making larger changes.
Bug: webp:533
Change-Id: I2e1ba42156970d579a52bd183707a037e65fd900
similar to '* const', __restrict needs to be included in the
declaration to avoid warnings like:
src\dsp\alpha_processing.c(429): warning C4028: formal parameter 1
different from declaration
this change also moves WEBP_RESTRICT to dsp.h to avoid a circular
dependency between it and utils.h which already includes dsp.h

Between 3.17.0 and 3.18.2 check_cxx_compiler_flag() sets a normal
variable at parent scope while check_cxx_source_compiles() continues to
set an internal cache variable, so we unset both to avoid the failure /
success state persisting between checks.
This was fixed in 3.18.3 [1], but regressed shortly afterward [2];
currently seen with 3.20.0 installed via homebrew.

this will provide the main libraries and their supporting examples by
default if external library requirements (e.g., gif2webp+libgif) are
met.
Bug: webp:501
Change-Id: I593adf9222698e2dc5a2199909949c7fea1273b2
this ensures the defaults are set properly before testing conditions for
enabling certain binaries. previously anim_diff would need
--enable-libwebpdemux to be explicitly added though it defaults to
enabled.
Bug: webp:501
Change-Id: Ifac68eac7096b39e98d0025e07a37b0be3d32c0a
this can help with some aliasing issues with some versions of clang/gcc,
similar to:
3e265136 Add WEBP_RESTRICT & use it in VP8BitReader
Change-Id: I863e53cc9d707c9a4b21373ca743c3089aed012e
this should be the full path to the installed headers to be added to the
client code's search path, e.g., /usr/local/include when including
<webp/decode.h>
Bug: webp:509
Change-Id: I756249876d8de421c9a33513221fb635157560ef
this enables cases that might trigger overflows, but increases the risk
of OOM and timeouts
Bug: chromium:1196850
Change-Id: I317b5109525646731e762faa3c34ed28a27595dc
Check encoded_frames_ count and call FlushFrames if necessary after
IncreasePreviousDuration. Avoids an overflow in encoded_frames_[] with
-kmax 0 and an assertion failure related to the previous and keyframe
durations when a frame is forced in this way.

Marking the `VP8BitReader` as `__restrict__` helps the compiler generate
better code avoiding issues related to aliasing (re-loads/stores).

use 64-bit math in calculating the offsets as they may exceed 32-bits

64-bit math as the number of output lines is variable and may still
