makefile

#ifdef INTEGER #include "ibp.h" #else #include "rbp.h" #endif /* built-in C functions */

#
# This makefile can be used to make all 4 programs but note that
# it is designed to make changing the integer version bp fast
# by keeping its object files around.  The other 3 programs erase
# their object files.
#
# Below, where I say 32-bit floating point or 64-bit floating point,
# note that all the programs use some floating point instructions even
# the integer versions, bp and sbp.  In standard UNIX C all floating
# point arithmetic is done as double so using double values actually is
# faster than using float values because all the covnersions take time.
# To use float rather than double define FLOAT like so:  -DFLOAT
#
# To get the compiler to use 32-bit DOS settings include: -DDOS32
# To get the compiler to use 16-bit DOS settings include: -DDOS16
#
# If you want bp or sbp to produce code that uses the exact derivative
# when computing weight changes use: -DEXACTDERIV.  There is really no
# reason to do this unless you some kind of purist.
#
# Below are the settings I've been using for Zortech 3.1.  The -f flag
# in the ZORTECH CFLAGS forces hardware floating point instructions to
# be generated.  In Zortech 3.1 this also generates checks on
# comparisons involving NaNs.  To skip these checks you an use -ff with
# version 3.1.  The -o is for optimize, -m is used to give the memory
# model.  Note that in the following makefile I don't use the Zortech
# optimization flag -o in the CFLAGS, instead it is used in the
# definitions for the creation of io.obj, misc.obj and int.obj because
# only these routines are worth optimizing and optimizing bp.c takes a
# minute or two on a 486/33.  In Zortech 3.0 the optimizer bombs when it
# optimizes io.obj, so if you have that version, remove the -o.  As its
# set up in this makefile, sbp, srbp and bp will not be optimized.  Of
# course, optimizing bp is worthwhile but for that use the makereal
# makefile.
