- fix formatting
- fix type conversion
- fix no-op arithmetic with null-pointer
- improve performance of hash_longest_match64
- go: detect read after close
- java decoder: support compound dictionary
- remove executable flag on non-scripts
Add an option to avoid building shared libraries (for building with EMCC)
Drive-by:
* maven: ramp up java level to minimal required
* travis: replace deprecated clang-5.0 with clang-7
* maven: fallback to jdk10 to void javadoc bug
* Verbose CLI + start pulling "Shared-Brotli"
* vesbose CLI output; fix#666
* pull `SHIFT` transforms; currently this is semantically dead code;
later it will be used by "Shared-Brotli"
Make sure the travis CI aarch32 bot tests NEON, and also that running
CROSS_COMPILE=arm-linux-gnueabihf make enables the use of NEON to
accelerate the back-reference copying.
The macro that checks for NEON support should be __ARM_NEON, not
__ARM_NEON__. [1]
AArch64 compilers define __ARM_NEON but not __ARM_NEON__.
AArch32 compilers currently seem to define both, but could be within their
rights to drop __ARM_NEON__ in future versions.
This change moves the check into the common/platform.h file, checks for
both forms, and sets BROTLI_TARGET_NEON if NEON support is available.

* platform: add macro for using the 'aligned' attribute
* decode: add accessor macros for HuffmanCode fields
Adds a constructor function for building HuffmanCode values
so they can be accessed quickly on different architectures.
Also adds macros for marking a HuffmanCode table pointer
that can be accessed quickly (BROTLI_HC_MARK_TABLE_FOR_FAST_LOAD),
adjusting the index into that table (BROTLI_HC_ADJUST_TABLE_INDEX),
and getting the .bits or .value fields out of the table at the
current index (BROTLI_HC_GET_BITS/VALUE).
For example, assuming |table| contains a HuffmanCode pointer:
BROTLI_HC_MARK_TABLE_FOR_FAST_LOAD(table);
BROTLI_HC_ADJUST_TABLE_INDEX(table, index_into_table);
*bits = BROTLI_HC_GET_BITS(table);
*value = BROTLI_HC_GET_VALUE(table);
BROTLI_HC_ADJUST_TABLE_INDEX(table, offset);
*bits2 = BROTLI_HC_GET_BITS(table);
*value2 = BROTLI_HC_GET_VALUE(table);
All uses of the HuffmanCode have been updated appropriately.
* decode: add alternative accessors for HuffmanCode on Arm AArch32
* build: add cross-compilation support to make
Set CROSS_COMPILE when running make to use the selected cross
compilation toolchain, such as arm-linux-gnueabihf, or
aarch64-linux-gnu.
Testing requires the presence of qemu - 'qemu-$(ARCH)' will be executed,
where ARCH is the first part of the toolchain triplet.
* build: add cross-compilation support to cmake
If C_COMPILER/CXX_COMPILER/CC/CXX are found to have cross-compilation
triplets in front of the compiler, then qemu will be used to execute the
tests.
* CI: add arm-linux-gnueabihf-gcc builder to Travis
The version of qemu available in Ubuntu trusty (as provided by Travis)
appears to have a bug in qemu-aarch64, which leads to the compatibility
tests failing on some inputs, erroneously rejecting the input as
corrupt.
Once Travis supports xenial, we could add an aarch64-gnu-linux-gcc
builder as well.
* CI: propagate cmake errors out of .travis.sh
Seems like even if cmake fails, the error isn't picked up by Travis.
Set bundled mode to ON when parent directory is not empty. Due to the
peculiarities of CMake if, comparing an undefined variable to the empty
string is false, so this likely never triggered.
Ensures that Aarch32 Arm builds with an Armv8 compiler do not set
BROTLI_64_BITS.
This scenario is possible with ChromeOS builds, as they may use a
toolchain with the target armv7-cros-gnueabi, but with -march=armv8.
This will set __ARM_ARCH to 8 (defining BROTLI_TARGET_ARMV8), but will
also set __ARM_32BIT_STATE and not __ARM_64BIT_STATE. Without this,
illegal 64-bit non-word-aligned reads (LDRD) may be emitted.
Also fix unaligned 64-bit reads on AArch32 - STRD was still possible to
emit.

Our dist tarball is missing hash_rolling_inc.h and
hash_composite_inc.h, which causes subsequent autotools
builds to fail. Fix this by adding it to the sources list.

* Update go_library to use standard importpath
Instead of using go_prefix, which is deprecated, the importpath attribute is made explicit.
* Add description to go/BUILD
* Inverse bazel workspace tree.
Now each subproject directly depends on root (c) project.
This helps to mitigate Bazel bug bazelbuild/bazel#2391; short summary:
Bazel does not work if referenced subproject `WORKSPACE` uses any
repositories that embedding project does not.
Bright side: building C project is much faster;
no need to download closure, go and JDK...
