Last change on this file since 724b58a was 9db5b66, checked in by Jakub Jermar <jakub@…>, 20 years ago

Move architecture independent memcopy() and memsetb() out of MIPS subtree and place them in src/lib/ as _memcopy() and _memsetb().
Add MIPS native memsetb().
Add IA-64 native memcpy().

More complete and *almost* functional versions of IA-64 context_save() and context_restore().
