If the target can't, then it needs the memcpy anyways. libbb/hash_md5_sha.c: In function 'common64_end': libbb/hash_md5_sha.c:87:4: warning: dereferencing type-punned pointer will break strict-aliasing rules *(uint64_t *) (&ctx->wbuffer[64 - 8]) = t; libbb/hash_md5_sha.c: In function 'sha512_end': libbb/hash_md5_sha.c:886:4: warning: dereferencing type-punned pointer will break strict-aliasing rules *(uint64_t *) (&ctx->wbuffer[128 - 8]) = t; libbb/hash_md5_sha.c:889:4: warning: dereferencing type-punned pointer will break strict-aliasing rules *(uint64_t *) (&ctx->wbuffer[128 - 16]) = t; Signed-off-by: Mike Frysinger <vapier@gentoo.org>
