/**
|
||
|
|
* Fuzz target interface.
|
||
|
|
* Fuzz targets have some common parameters passed as macros during compilation.
|
||
|
|
* Check the documentation for each individual fuzzer for more parameters.
|
||
|
|
*
|
||
|
|
* @param FUZZ_RNG_SEED_SIZE:
|
||
|
|
* The number of bytes of the source to look at when constructing a seed
|
||
|
|
* for the deterministic RNG. These bytes are discarded before passing
|
||
|
|
* the data to lz4 functions. Every fuzzer initializes the RNG exactly
|
||
|
|
* once before doing anything else, even if it is unused.
|
||
|
|
* Default: 4.
|
||
|
|
* @param LZ4_DEBUG:
|
||
|
|
* This is a parameter for the lz4 library. Defining `LZ4_DEBUG=1`
|
||
|
|
* enables assert() statements in the lz4 library. Higher levels enable
|
||
|
|
* logging, so aren't recommended. Defining `LZ4_DEBUG=1` is
|
||
|
|
* recommended.
|
||
|
|
* @param LZ4_FORCE_MEMORY_ACCESS:
|
||
|
|
* This flag controls how the zstd library accesses unaligned memory.
|
||
|
|
* It can be undefined, or 0 through 2. If it is undefined, it selects
|
||
|
|
* the method to use based on the compiler. If testing with UBSAN set
|
||
|
|
* MEM_FORCE_MEMORY_ACCESS=0 to use the standard compliant method.
|
||
|
|
* @param FUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION
|
||
|
|
* This is the canonical flag to enable deterministic builds for fuzzing.
|
||
|
|
* Changes to zstd for fuzzing are gated behind this define.
|
||
|
|
* It is recommended to define this when building zstd for fuzzing.
