3ebb2d30 | 2023-08-18 02:55:01 | Move serialized dictionary feature behind the flag. BROTLI_SHARED_DICTIONARY_SERIALIZED enum value is a part of API, but it should not be used (will cause failures). Changing how serialized dictionaries work won't be considered as an API change, until this feature is enabled. Enabling this feature in the future will be considered as a "compatible" change.

641bec0e | 2022-12-16 12:42:42 | CMake: Allow using BUILD_SHARED_LIBS to choose static/shared libs (#655) By convention projects using CMake which can build either static or shared libraries use a BUILD_SHARED_LIBS flag to allow selecting between both: the add_library() command automatically switches between both using this variable when the library kind is not passed to add_library(). It is also usual to expose the BUILD_SHARED_LIBS as an user-facing setting with the option() command. This way, the following will both work as expected: % cmake -DBUILD_SHARED_LIBS=OFF ... % cmake -DBUILS_SHARED_LIBS=ON ... This is helpful for distributions which need (or want) to build only static libraries. | |

cc7a74f1 | 2018-10-08 14:40:11 | decode: fix NEON inclusion (#714) 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. [1] Section 6.5.4 of the ARM C Language Extensions. (At the time of writing, the latest version was Release 2.1.) | |

9402ac5c | 2018-09-27 12:15:46 | decode: faster huffman code loading on 32-bit Arm (#703) * 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 | |

d4cd6cdf | 2018-07-25 10:43:06 | platform: fix unaligned 64-bit accesses on AArch32 (#702) 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. | |

35e69fc7 | 2018-02-26 09:04:36 | New feature: "Large Window Brotli" (#640) * New feature: "Large Window Brotli" By setting special encoder/decoder flag it is now possible to extend LZ-window up to 30 bits; though produced stream will not be RFC7932 compliant. Added new dictionary generator - "DSH". It combines speed of "Sieve" and quality of "DM". Plus utilities to prepare train corpora (remove unique strings). Improved compression ratio: now two sub-blocks could be stitched: the last copy command could be extended to span the next sub-block. Fixed compression ineffectiveness caused by floating numbers rounding and wrong cost heuristic. Other C changes: - combined / moved `context.h` to `common` - moved transforms to `common` - unified some aspects of code formatting - added an abstraction for encoder (static) dictionary - moved default allocator/deallocator functions to `common` brotli CLI: - window size is auto-adjusted if not specified explicitly Java: - added "eager" decoding both to JNI wrapper and pure decoder - huge speed-up of `DictionaryData` initialization * Add dictionaryless compressed dictionary * Fix `sources.lst` * Fix `sources.lst` and add a note that `libtool` is also required. * Update setup.py * Fix `EagerStreamTest` * Fix BUILD file * Add missing `libdivsufsort` dependency * Fix "unused parameter" warning. | |
