-# This shell script provides a wrapper for ld under AIX in order to

-# create the .exp file required for linking. Its arguments consist

-# of the name and arguments that would normally be provided to the

-# ld command. This script extracts the names of the object files

-# from the argument list, creates a .exp file describing all of the

-# symbols exported by those files, and then invokes "ldCmd" to

-# perform the real link.

-# Create the export file from all of the object files, using nm followed

-# by sed editing. Here are some tricky aspects of this:

-#

-# 1. Nm produces different output under AIX 4.1 than under AIX 3.2.5;

-# the following statements handle both versions.

-# 2. Use the -g switch to nm instead of -e under 4.1 (this shows just

-# externals, not statics; -g isn't available under 3.2.5, though).

-# 3. Eliminate lines that end in ":": these are the names of object

-# files (relevant in 4.1 only).

-# 4. Eliminate entries with the "U" key letter; these are undefined

-# symbols (relevant in 4.1 only).

-# 5. Eliminate lines that contain the string "0|extern" preceded by space;

-# in 3.2.5, these are undefined symbols (address 0).

-# 6. Eliminate lines containing the "unamex" symbol. In 3.2.5, these

-# are also undefined symbols.

-# 7. If a line starts with ".", delete the leading ".", since this will

-# just cause confusion later.

-# 8. Eliminate everything after the first field in a line, so that we're

-# left with just the symbol name.
