ash: undo "tokname hack"
dash has tokendlist[] array to decide which tokens end lists. We store it as first byte of each tokname_array[i]. Switch to bit array, name it like dash (tokendlist), drop special 1st byte of tokname_array[i]. This brings us closer to dash, and shrinks the binary, because many more string aliasing opportunities are now open: function old new delta pstrcmp1 - 16 +16 readtoken1 2852 2858 +6 list 326 327 +1 pstrcmp 16 15 -1 tokname 45 42 -3 ------------------------------------------------------------------------------ (add/remove: 1/0 grow/shrink: 2/2 up/down: 23/-4) Total: 19 bytes text data bss dec hex filename 943556 916 14292 958764 ea12c busybox_old 943463 916 14292 958671 ea0cf busybox_unstripped ^^^^^^^ note this!
