Each one 21# corresponds to a drastically different dump format. The first on is 22# the original dump format on a 4.1 BSD or earlier file system. The 23# second marks the change between the 4.1 file system and the 4.2 file 24# system. The Third marks the changing of the block size from 1K 25# to 2K to be compatible with an IDC file system. The fourth indicates 26# a dump that is dependent on Convex Storage Manager, because data in 27# secondary storage is not physically contained within the dump. 28# The restore program uses these number to determine how the data is 29# to be extracted. 30# 3124 belong =60011 dump format, 4.1 BSD or earlier 3224 belong =60012 dump format, 4.2 or 4.3 BSD without IDC 3324 belong =60013 dump format, 4.2 or 4.3 BSD (IDC compatible) 3424 belong =60014 dump format, Convex Storage Manager by-reference dump 35# 36# what follows is a bunch of bit-mask checks on the flags field of the opthdr. 37# If there is no `=' sign, assume just checking for whether the bit is set? 38# 390 belong 0601 Convex SOFF 40>88 belong&0x000f0000 =0x00000000 c1 41>88 belong &0x00010000 c2 42>88 belong &0x00020000 c2mp 43>88 belong &0x00040000 parallel 44>88 belong &0x00080000 intrinsic 45>88 belong &0x00000001 demand paged 46>88 belong &0x00000002 pre-paged 47>88 belong &0x00000004 non-swapped 48>88 belong &0x00000008 POSIX 49# 50>84 belong &0x80000000 executable 51>84 belong &0x40000000 object 52>84 belong&0x20000000 =0 not stripped 53>84 belong&0x18000000 =0x00000000 native fpmode 54>84 belong&0x18000000 =0x10000000 ieee fpmode 55>84 belong&0x18000000 =0x18000000 undefined fpmode 56# 570 belong 0605 Convex SOFF core 58# 590 belong 0607 Convex SOFF checkpoint 60>88 belong&0x000f0000 =0x00000000 c1 61>88 belong &0x00010000 c2 62>88 belong &0x00020000 c2mp 63>88 belong &0x00040000 parallel 64>88 belong &0x00080000 intrinsic 65>88 belong &0x00000008 POSIX 66# 67>84 belong&0x18000000 =0x00000000 native fpmode 68>84 belong&0x18000000 =0x10000000 ieee fpmode 69>84 belong&0x18000000 =0x18000000 undefined fpmode 70
