annotate lib/sha512.c @ 10128:92a80b637ea1

avoid unaligned access errors, e.g., on sparc * lib/sha512.c (sha512_conclude_ctx): Use set_uint64 rather than direct access through a possibly-unaligned uint64* pointer. * lib/sha256.c (sha256_conclude_ctx): Use set_uint32 rather than direct access through a possibly-unaligned uint32* pointer. Prompted by this patch from Tom "spot" Callaway: http://thread.gmane.org/gmane.comp.gnu.coreutils.bugs/13638
