# This shell script provides a wrapper for ld under AIX in order to
6
# create the .exp file required for linking. Its arguments consist
7
# of the name and arguments that would normally be provided to the
8
# ld command. This script extracts the names of the object files
9
# from the argument list, creates a .exp file describing all of the
10
# symbols exported by those files, and then invokes "ldCmd" to
11
# perform the real link.

# Create the export file from all of the object files, using nm followed
70
# by sed editing. Here are some tricky aspects of this:
72
# 1. Nm produces different output under AIX 4.1 than under AIX 3.2.5;
73
# the following statements handle both versions.
74
# 2. Use the -g switch to nm instead of -e under 4.1 (this shows just
75
# externals, not statics; -g isn't available under 3.2.5, though).
76
# 3. Eliminate lines that end in ":": these are the names of object
77
# files (relevant in 4.1 only).
78
# 4. Eliminate entries with the "U" key letter; these are undefined
79
# symbols (relevant in 4.1 only).
80
# 5. Eliminate lines that contain the string "0|extern" preceded by space;
81
# in 3.2.5, these are undefined symbols (address 0).
82
# 6. Eliminate lines containing the "unamex" symbol. In 3.2.5, these
83
# are also undefined symbols.
84
# 7. If a line starts with ".", delete the leading ".", since this will
85
# just cause confusion later.
86
# 8. Eliminate everything after the first field in a line, so that we're
87
# left with just the symbol name.
