When not using a separate object directory this just becomes # # cd tune # perl many.pl [-t] ... # # # 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. # # K&R compilers are supported via the same ansi2knr mechanism used by # automake, though it's hard to believe anyone will have much interest in # measuring a compiler so old that it doesn't even have an ANSI mode. # # 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. use strict; use File::Basename; use Getopt::Std; my %opt; getopts('t', \%opt); my @DIRECTORIES = @ARGV; if (defined $ENV{directories}) { push @DIRECTORIES, @{$ENV{directories}} } # regexp - matched against the start of the filename.
