Each one 23# corresponds to a drastically different dump format. The first on is 24# the original dump format on a 4.1 BSD or earlier file system. The 25# second marks the change between the 4.1 file system and the 4.2 file 26# system. The Third marks the changing of the block size from 1K 27# to 2K to be compatible with an IDC file system. The fourth indicates 28# a dump that is dependent on Convex Storage Manager, because data in 29# secondary storage is not physically contained within the dump. 30# The restore program uses these number to determine how the data is 31# to be extracted. 32# 3324 belong =60011 dump format, 4.1 BSD or earlier 3424 belong =60012 dump format, 4.2 or 4.3 BSD without IDC 3524 belong =60013 dump format, 4.2 or 4.3 BSD (IDC compatible) 3624 belong =60014 dump format, Convex Storage Manager by-reference dump 37# 38# what follows is a bunch of bit-mask checks on the flags field of the opthdr. 39# If there is no `=' sign, assume just checking for whether the bit is set? 40# 410 belong 0601 Convex SOFF 42>88 belong&0x000f0000 =0x00000000 c1 43>88 belong &0x00010000 c2 44>88 belong &0x00020000 c2mp 45>88 belong &0x00040000 parallel 46>88 belong &0x00080000 intrinsic 47>88 belong &0x00000001 demand paged 48>88 belong &0x00000002 pre-paged 49>88 belong &0x00000004 non-swapped 50>88 belong &0x00000008 POSIX 51# 52>84 belong &0x80000000 executable 53>84 belong &0x40000000 object 54>84 belong&0x20000000 =0 not stripped 55>84 belong&0x18000000 =0x00000000 native fpmode 56>84 belong&0x18000000 =0x10000000 ieee fpmode 57>84 belong&0x18000000 =0x18000000 undefined fpmode 58# 590 belong 0605 Convex SOFF core 60# 610 belong 0607 Convex SOFF checkpoint 62>88 belong&0x000f0000 =0x00000000 c1 63>88 belong &0x00010000 c2 64>88 belong &0x00020000 c2mp 65>88 belong &0x00040000 parallel 66>88 belong &0x00080000 intrinsic 67>88 belong &0x00000008 POSIX 68# 69>84 belong&0x18000000 =0x00000000 native fpmode 70>84 belong&0x18000000 =0x10000000 ieee fpmode 71>84 belong&0x18000000 =0x18000000 undefined fpmode 72
