The Makefiles call the respective interpreter explicitly, but this makes it easier to use the scripts manually. Signed-off-by: Michal Marek <mmarek@suse.cz>

# Based on the vmlinux file create the System.map file
|
|
# System.map is used by module-init tools and some debugging
|
|
# tools to retrieve the actual addresses of symbols in the kernel.
|
|
#
|
|
# Usage
|
|
# mksysmap vmlinux System.map
|
|
|
|
|
|
#####
|
|
# Generate System.map (actual filename passed as second argument)
|
|
|
|
# $NM produces the following output:
|
|
# f0081e80 T alloc_vfsmnt
|
|
|
|
# The second row specify the type of the symbol:
|
|
# A = Absolute
|
|
# B = Uninitialised data (.bss)
|
|
# C = Common symbol
|
|
# D = Initialised data
|
|
# G = Initialised data for small objects
|
|
# I = Indirect reference to another symbol
|
|
# N = Debugging symbol
|
|
# R = Read only
|
|
# S = Uninitialised data for small objects
|
|
# T = Text code symbol
|
|
# U = Undefined symbol
|
|
# V = Weak symbol
|
|
# W = Weak symbol
|
|
# Corresponding small letters are local symbols
|
|
|
|
# For System.map filter away:
|
|
# a - local absolute symbols
|
|
# U - undefined global symbols
|
|
# N - debugging symbols
|
|
# w - local weak symbols
|
|
|
|
# readprofile starts reading symbols when _stext is found, and
|
|
# continue until it finds a symbol which is not either of 'T', 't',
|
|
# 'W' or 'w'. __crc_ are 'A' and placed in the middle
|
|
# so we just ignore them to let readprofile continue to work.
|
|
# (At least sparc64 has __crc_ in the middle).
