It is not feasible to insert comments in a multi-line shell command.
Use sed, and move comments close to the code.

# Generate System.map (actual filename passed as second argument)

# The following refers to the symbol type as per nm(1).



# 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'.

#

# Ignored prefixes:

#  $                    - local symbols for ARM, MIPS, etc.

#  .L                   - local labels, .LBB,.Ltmpxxx,.L__unnamed_xx,.LASANPC, etc.

#  __crc_               - modversions

#  __kstrtab_           - EXPORT_SYMBOL (symbol name)

#  __kstrtabns_         - EXPORT_SYMBOL (namespace)
