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. | |
