# Usage: cd $builddir/tune
# perl $srcdir/tune/many.pl [-t] <files/dirs>...
#
# Output: speed-many.c
# try-many.c
# Makefile.many
#
# Make alternate versions of various mpn routines available for measuring
# and testing.
#
# The $srcdir and $builddir in the invocation above just means the script
# lives in the tune source directory, but should be run in the tune build
# directory. When not using a separate object directory this just becomes
#
# cd tune
# perl many.pl [-t] <files/dirs>...
#
#
# SINGLE FILES
#
# Suppose $HOME/newcode/mul_1_experiment.asm is a new implementation of
# mpn_mul_1, then
#
# cd $builddir/tune
# perl $srcdir/tune/many.pl $HOME/newcode/mul_1_experiment.asm
#
# will produce rules and renaming so that a speed program incorporating it
# can be built,
#
# make -f Makefile.many speed-many
#
# then for example it can be compared to the standard mul_1,
#
# ./speed-many -s 1-30 mpn_mul_1 mpn_mul_1_experiment
#
# An expanded try program can be used to check correctness,
#
# make -f Makefile.many try-many
#
# and run
#
# ./try-many mpn_mul_1_experiment
#
# Files can be ".c", ".S" or ".asm". ".s" files can't be used because they
# don't get any preprocessing so there's no way to do renaming of their
# functions.
#
#
# WHOLE DIRECTORIES
#
# If a directory is given, then all files in it will be made available.
# For example,
#
# cd $builddir/tune
# perl $srcdir/tune/many.pl $HOME/newcode
#
# Each file should have a suffix, like "_experiment" above.
#
#
# MPN DIRECTORIES
#
# mpn directories from the GMP source tree can be included, and this is a
# convenient way to compare multiple implementations suiting different chips
# in a CPU family. For example the following would make all x86 routines
# available,
#
# cd $builddir/tune
# perl $srcdir/tune/many.pl `find $srcdir/mpn/x86 -type d`
#
# On a new x86 chip a comparison could then be made to see how existing code
# runs. For example,
#
# make -f Makefile.many speed-many
# ./speed-many -s 1-30 -c \
# mpn_add_n_x86 mpn_add_n_pentium mpn_add_n_k6 mpn_add_n_k7
#
# Files in "mpn" subdirectories don't need the "_experiment" style suffix
# described above, instead a suffix is constructed from the subdirectory.
# For example "mpn/x86/k7/mmx/mod_1.asm" will generate a function
# mpn_mod_1_k7_mmx. The rule is to take the last directory name after the
# "mpn", or the last two if there's three or more. (Check the generated
# speed-many.c if in doubt.)
#
#
# GENERIC C
#
# The mpn/generic directory can be included too, just like any processor
# specific directory. This is a good way to compare assembler and generic C
# implementations. For example,
#
# cd $builddir/tune
# perl $srcdir/tune/many.pl $srcdir/mpn/generic
#
# or if just a few routines are of interest, then for example
#
# cd $builddir/tune
# perl $srcdir/tune/many.pl \
# $srcdir/mpn/generic/lshift.c \
# $srcdir/mpn/generic/mod_1.c \
# $srcdir/mpn/generic/aorsmul_1.c
#
# giving mpn_lshift_generic etc.
#
#
# TESTS/DEVEL PROGRAMS
#
# Makefile.many also has rules to build the tests/devel programs with suitable
# renaming, and with some parameters for correctness or speed. This is less
# convenient than the speed and try programs, but provides an independent
# check. For example,
#
# make -f Makefile.many tests_mul_1_experimental
# ./tests_mul_1_experimental
#
# and for speed
#
# make -f Makefile.many tests_mul_1_experimental_sp
# ./tests_mul_1_experimental_sp
#
# Not all the programs support speed measuring, in which case only the
# correctness test will be useful.
#
# The parameters for repetitions and host clock speed are -D defines. Some
# defaults are provided at the end of Makefile.many, but probably these will
# want to be overridden. For example,
#
# rm tests_mul_1_experimental.o
# make -f Makefile.many \
# CFLAGS_TESTS="-DSIZE=50 -DTIMES=1000 -DRANDOM -DCLOCK=175000000" \
# tests_mul_1_experimental
# ./tests_mul_1_experimental
#
#
# OTHER NOTES
#
# The mappings of file names to functions, and the macros to then use for
# speed measuring etc are driven by @table below. The scheme isn't
# completely general, it's only got as many variations as have been needed
# so far.
#
# Some functions are only made available in speed-many, or others only in
# try-many. An @table entry speed=>none means no speed measuring is
# available, or try=>none no try program testing. These can be removed
# if/when the respective programs get the necessary support.
#
# If a file has "1c" or "nc" carry-in entrypoints, they're renamed and made
# available too. These are recognised from PROLOGUE or MULFUNC_PROLOGUE in
# .S and .asm files, or from a line starting with "mpn_foo_1c" in a .c file
# (possibly via a #define), and on that basis are entirely optional. This
# entrypoint matching is done for the standard entrypoints too, but it would
# be very unusual to have for instance a mul_1c without a mul_1.
#
# Some mpz files are recognized. For example an experimental copy of
# mpz/powm.c could be included as powm_new.c and would be called
# mpz_powm_new. So far only speed measuring is available for these.
#
# For the ".S" and ".asm" files, both PIC and non-PIC objects are built.
# The PIC functions have a "_pic" suffix, for example "mpn_mod_1_k7_mmx_pic".
# This can be ignored for routines that don't differ for PIC, or for CPUs
# where everything is PIC anyway.
#
# The "-t" option can be used to print a trace of the files found and what's
# done with them. A great deal of obscure output is produced, but it can
# indicate where or why some files aren't being recognised etc. For
# example,
#
# cd $builddir/tune
# perl $srcdir/tune/many.pl -t $HOME/newcode/add_n_weird.asm
#
# In general, when including new code, all that's really necessary is that
# it will compile or assemble under the current configuration. It's fine if
# some code doesn't actually run due to bugs, or to needing a newer CPU or
# whatever, simply don't ask for the offending routines when invoking
# speed-many or try-many, or don't try to run them on sizes they don't yet
# support, or whatever.
#
#
# CPU SPECIFICS
#
# x86 - All the x86 code will assemble on any system, but code for newer
# chips might not run on older chips. Expect SIGILLs from new
# instructions on old chips.
#
# A few "new" instructions, like cmov for instance, are done as macros
# and will generate some equivalent plain i386 code when HAVE_HOST_CPU
# in config.m4 indicates an old CPU. It won't run fast, but it does
# make it possible to test correctness.
#
#
# INTERNALS
#
# The nonsense involving $ENV is some hooks used during development to add
# additional functions temporarily.
#
#
# FUTURE
#
# Maybe the C files should be compiled pic and non-pic too. Wait until
# there's a difference that might be of interest.
#
# Warn if a file provides no functions.
#
# Allow mpz and mpn files of the same name. Currently the mpn fib2_ui
# matching hides the mpz version of that. Will need to check the file
# contents to see which it is. Would be worth allowing an "mpz_" or "mpn_"
# prefix on the filenames to have working versions of both in one directory.
#
#
# LIMITATIONS
#
# Some of the command lines can become very long when a lot of files are
# included. If this is a problem on a given system the only suggestion is
# to run many.pl for just those that are actually wanted at a particular
# time.
#
# DOS 8.3 or SysV 14 char filesystems won't work, since the long filenames
# generated will almost certainly fail to be unique.
