2 # Based on the vmlinux file create the System.map file
3 # System.map is used by module-init tools and some debugging
4 # tools to retrieve the actual addresses of symbols in the kernel.
5 #
6 # Usage
7 # mksysmap vmlinux System.map
10 #####
11 # Generate System.map (actual filename passed as second argument)
13 # $NM produces the following output:
14 # f0081e80 T alloc_vfsmnt
16 # The second row specify the type of the symbol:
17 # A = Absolute
18 # B = Uninitialised data (.bss)
19 # C = Comon symbol
20 # D = Initialised data
21 # G = Initialised data for small objects
22 # I = Indirect reference to another symbol
23 # N = Debugging symbol
24 # R = Read only
25 # S = Uninitialised data for small objects
26 # T = Text code symbol
27 # U = Undefined symbol
28 # V = Weak symbol
29 # W = Weak symbol
30 # Corresponding small letters are local symbols
32 # For System.map filter away:
33 # a - local absolute symbols
34 # U - undefined global symbols
35 # w - local weak symbols
37 # readprofile starts reading symbols when _stext is found, and
38 # continue until it finds a symbol which is not either of 'T', 't',
39 # 'W' or 'w'. __crc_ are 'A' and placed in the middle
40 # so we just ignore them to let readprofile continue to work.
41 # (At least sparc64 has __crc_ in the middle).
