# FILE:         makexp_aix
# TYPE:         standalone executable
# SYSTEM:	AIX 3.2.5 and AIX 4
#
# DESCRIPTION:  This script creates an export list of ALL global symbols
#               from a list of object or archive files.
#
# USAGE:        makexp_aix <OutputFile> "<FirstLine>" <InputFile> ...
#
#               where:
#                      <OutputFile> is the target export list filename.
#                      <FirstLine> is the path/file string to be appended
#                         after the "#!" symbols in the first line of the
#                         export file. Passing "" means deferred resolution.
#                      <InputFile> is an object (.o) or an archive file (.a).

# Extract the symbol list using 'nm' which produces quite
# different output under AIX 4 than under AIX 3.2.5.
# The following handles both versions by using a common flagset.
# Here are some hidden tricks:
# 1. Use /usr/ccs/bin/nm. Relevant to AIX 3.2.5 which has
#    another version under /usr/ucb/bin/nm.
# 2. Use the -B flag to have a standard BSD representation
#    of the symbol list on both AIX 3.2.5 and AIX 4. The "-B"
#    flag is missing in the AIX 3.2.5 online usage help of 'nm'.
# 3. Use the -x flag to have a hex representation of the symbol
#    values. This fills the leading whitespaces on AIX 4,
#    thus simplifying the sed statement.
# 4. Eliminate all entries except those with either "B", "D"
#    or "T" key letters. We are interested only in the global
#    (extern) BSS, DATA and TEXT symbols. With the same statement
#    we eliminate object member lines relevant to AIX 4.
# 5. Eliminate entries containing a dot. We can have a dot only
#    as a symbol prefix, but such symbols are undefined externs.
# 6. Eliminate everything including the key letter, so that we're
#    left with just the symbol name.
# 7. Eliminate all entries containing two colons, like Class::method

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
