# FILE: ld_so_aix
# TYPE: executable, uses makexp_aix
# SYSTEM: AIX
#
# DESCRIPTION: Creates a shareable .o from a set of pre-compiled
# (unshared) .o files
#
# USAGE: ld_so_aix [CC] [arguments]
#
# ARGUMENTS: Same as for "ld". The following arguments are processed
# or supplied by this script (those marked with an asterisk
# can be overriden from command line):
#
# Argument Default value
# (*) -o [OutputFileName] -o shr.o
# (*) -e [EntryPointLabel] -e init[OutputBaseName]
# (*) -bE:[ExportFile] -bE:[OutputBaseName].exp
# (*) -bI:[ImportFile] -bI:./python.exp
# -bM:[ModuleType] -bM:SRE
# -bhalt:[Number] -bhalt:4
# -T[Number] -T512
# -H[Number] -H512
# -lm
#
# The compiler specific ("-lc" or "-lc_r", "-lpthreads",...)
# arguments will be automatically passed to "ld" according
# to the CC command provided as a first argument to this
# script. Usually, the same CC command was used to produce
# the pre-compiled .o file(s).
#
# NOTES: 1. Since "ld_so_aix" was originally written for building
# shared modules for the Python interpreter, the -e and
# -bI default values match Python's conventions. In
# Python, the entry point for a shared module is based
# on the module's name (e.g., the "mathmodule" will
# expect an entry point of "initmath").
# 2. The script accepts multiple .o or .a input files and
# creates a single (shared) output file. The export list
# that is created is based on the output file's basename
# with the suffix ".exp".
# 3. The resulting shared object file is left in the
# current directory.
# 4. Uncommenting the "echo" lines gives detailed output
# about the commands executed in the script.
#
#
# HISTORY: Oct-1996 -- Support added for multiple .o files --
# -- and optional arguments processing. --
# Chris Myers (myers@tc.cornell.edu), Keith Kwok
# (kkwok@tc.cornell.edu) and Vladimir Marangozov
#
# Aug-6-1996 -- Take care of the compiler specific --
# -- args by leaving CC to invoke "ld". --
# Vladimir Marangozov
#
# Jul-1-1996 -- Make sure to use /usr/ccs/bin/ld --
# -- Use makexp_aix for the export list. --
# Vladimir Marangozov (Vladimir.Marangozov@imag.fr)
#
# Manus Hand (mhand@csn.net) -- Initial code -- 6/24/96
