Fuzz target interface. Fuzz targets have some common parameters passed as macros during compilation. Check the documentation for each individual fuzzer for more parameters.

Parameters

STATEFUL_FUZZING	Define this to reuse state between fuzzer runs. This can be useful to test code paths which are only executed when contexts are reused. WARNING: Makes reproducing crashes much harder. Default: Not defined.
DEBUGLEVEL	This is a parameter for the zstd library. Defining DEBUGLEVEL=1 enables assert() statements in the zstd library. Higher levels enable logging, so aren't recommended. Defining DEBUGLEVEL=1 is recommended.
MEM_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.
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.

This fuzz target attempts to compress the fuzzed data with the simple compression function with an output buffer that may be too small to ensure that the compressor never crashes.

This fuzz target attempts to decompress the fuzzed data with the simple decompression function to ensure the decompressor never crashes.

This fuzz target performs a lz4 round-trip test (compress & decompress), compares the result with the original, and calls abort() on corruption.
