# Writes out all of the exported symbols to a file.
|
|
# This is needed on AIX as symbols are not exported
|
|
# by an executable by default and need to be listed
|
|
# specifically for export so that they can be used
|
|
# by native add-ons.
|
|
#
|
|
# The raw symbol data is obtained by using nm on
|
|
# the .a files which make up the node executable.

|
|
# -Xany processes symbols for both 32-bit and
|
|
# 64-bit (the default is for 32-bit only).
|
|
#
|
|
# -g selects only exported symbols.
|
|
#
|
|
# -C, -B and -p ensure that the output is in a
|
|
# format that can be easily parsed and converted
|
|
# into the required symbol.
|
|
#
|
|
# -C suppresses the demangling of C++ names.
|
|
# -B writes the output in BSD format.
|
|
# -p displays the info in a standard portable
|
|
# output format.
|
|
#
|
|
# Only include symbols if they are of the following
|
|
# types and don't start with a dot.
|
|
#
|
|
# T - Global text symbol.
|
|
# D - Global data symbol.
|
|
# B - Global bss symbol.
|
|
#
|
|
# The final sort allows removal of any duplicates.
|
|
#
|
|
# Symbols for the gtest libraries are excluded as
|
|
# they are not linked into the node executable.
