12 | * Fuzz target interface. |
13 | * Fuzz targets have some common parameters passed as macros during compilation. |
14 | * Check the documentation for each individual fuzzer for more parameters. |
15 | * |
16 | * @param STATEFUL_FUZZING: |
17 | * Define this to reuse state between fuzzer runs. This can be useful to |
18 | * test code paths which are only executed when contexts are reused. |
19 | * WARNING: Makes reproducing crashes much harder. |
20 | * Default: Not defined. |
21 | * @param DEBUGLEVEL: |
22 | * This is a parameter for the zstd library. Defining `DEBUGLEVEL=1` |
23 | * enables assert() statements in the zstd library. Higher levels enable |
24 | * logging, so aren't recommended. Defining `DEBUGLEVEL=1` is |
25 | * recommended. |
26 | * @param MEM_FORCE_MEMORY_ACCESS: |
27 | * This flag controls how the zstd library accesses unaligned memory. |
28 | * It can be undefined, or 0 through 2. If it is undefined, it selects |
29 | * the method to use based on the compiler. |
30 | * @param FUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION |
31 | * This is the canonical flag to enable deterministic builds for fuzzing. |
32 | * Changes to zstd for fuzzing are gated behind this define. |
33 | * It is recommended to define this when building zstd for fuzzing. |
34 | * @param FUZZ_THIRD_PARTY_SEQ_PROD |
35 | * This flag allows sequence producer plugin authors to replace the built-in |
36 | * default sequence producer with their own code. If you are not a plugin |
37 | * author, you should not define this flag. See the docs at |
38 | * fuzz_third_party_seq_prod.h for more information. |
