7 | | /* Macros for compiler / platform specific features and build options. |
8 | | |
9 | | Build options are: |
10 | | * BROTLI_BUILD_32_BIT disables 64-bit optimizations |
11 | | * BROTLI_BUILD_64_BIT forces to use 64-bit optimizations |
12 | | * BROTLI_BUILD_BIG_ENDIAN forces to use big-endian optimizations |
13 | | * BROTLI_BUILD_ENDIAN_NEUTRAL disables endian-aware optimizations |
14 | | * BROTLI_BUILD_LITTLE_ENDIAN forces to use little-endian optimizations |
15 | | * BROTLI_BUILD_PORTABLE disables dangerous optimizations, like unaligned |
16 | | read and overlapping memcpy; this reduces decompression speed by 5% |
17 | | * BROTLI_BUILD_NO_RBIT disables "rbit" optimization for ARM CPUs |
18 | | * BROTLI_DEBUG dumps file name and line number when decoder detects stream |
19 | | or memory error |
20 | | * BROTLI_ENABLE_LOG enables asserts and dumps various state information |
