| * Introduce LZ4_STATIC_LINKING_ONLY_DISABLE_MEMORY_ALLOCATIONTakayuki Matsuoka2022-07-312-1/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This changeset introduces new compile time switch macro LZ4_STATIC_LINKING_ONLY_DISABLE_MEMORY_ALLOCATION which removes the following functions when it's defined. ``` // lz4.c LZ4_createStream LZ4_freeStream LZ4_createStreamDecode LZ4_freeStreamDecode LZ4_create // legacy // lz4hc.c LZ4_createStreamHC(void) LZ4_freeStreamHC LZ4_createHC // legacy LZ4_freeHC // legacy ``` These functions uses dynamic memory allocation functions such as malloc() and free(). It'll be useful for freestanding environment which doesn't have these allocation functions. Since this change breaks API, this macro is only valid with lz4 as a static linked object.

| |/ | | | | | | | | | | | | | | This changeset introduces the following external macros. - Add new macro LZ4_memset() which enables to inject external function as memset(). - Similar macro LZ4_memmove() for memmove(). - In same manner, LZ4_memcpy() also can be overriden by external macro.

There is a suspicion that the test is using too much stack. Fixing that, + adding traces, to get more information if it fails again.
