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