Instead of using packed attribute hack, just use aligned attribute. It improves code generation on armv6 and armv7, and slightly improves code generation on aarch64. GCC generates identical code to regular aligned access on ARMv6 for all versions between 4.5 and trunk, except GCC 5 which is buggy and generates the same (bad) code as packed access: https://gcc.godbolt.org/z/hq37rz7sb

/**
|
|
* 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 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.
|
|
* @param 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.
|
|
* @param 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.
|
|
* @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.
