#!/usr/local/bin/perl -w # # generate a .def file # # It does this by parsing the header files and looking for the # prototyped functions: it then prunes the output. # # Intermediary files are created, call libeay.num and ssleay.num,... # Previously, they had the following format: # # routine-name nnnn # # But that isn't enough for a number of reasons, the first on being that # this format is (needlessly) very Win32-centric, and even then... # One of the biggest problems is that there's no information about what # routines should actually be used, which varies with what crypto algorithms # are disabled. Also, some operating systems (for example VMS with VAX C) # need to keep track of the global variables as well as the functions. # # So, a remake of this script is done so as to include information on the # kind of symbol it is (function or variable) and what algorithms they're # part of. This will allow easy translating to .def files or the corresponding # file in other operating systems (a .opt file for VMS, possibly with a .mar # file). # # The format now becomes: # # routine-name nnnn info # # and the "info" part is actually a colon-separated string of fields with # the following meaning: # # existence:platform:kind:algorithms # # - "existence" can be "EXIST" or "NOEXIST" depending on if the symbol is # found somewhere in the source, # - "platforms" is empty if it exists on all platforms, otherwise it contains # comma-separated list of the platform, just as they are if the symbol exists # for those platforms, or prepended with a "!" if not. This helps resolve # symbol name replacements for platforms where the names are too long for the # compiler or linker, or if the systems is case insensitive and there is a # clash. This script assumes those redefinitions are place in the file # crypto/symhacks.h. # The semantics for the platforms list is a bit complicated. The rule of # thumb is that the list is exclusive, but it seems to mean different things. # So, if the list is all negatives (like "!VMS,!WIN16"), the symbol exists # on all platforms except those listed. If the list is all positives (like # "VMS,WIN16"), the symbol exists only on those platforms and nowhere else. # The combination of positives and negatives will act as if the positives # weren't there. # - "kind" is "FUNCTION" or "VARIABLE". The meaning of that is obvious. # - "algorithms" is a comma-separated list of algorithm names. This helps # exclude symbols that are part of an algorithm that some user wants to # exclude. # my $crypto_num= "util/libeay.num"; my $ssl_num= "util/ssleay.num"; my $do_update = 0; my $do_rewrite = 0; my $do_crypto = 0; my $do_ssl = 0; my $do_ctest = 0; my $do_ctestall = 0; my $rsaref = 0; my $VMS=0; my $W32=0; my $W16=0; my $NT=0; # Set this to make typesafe STACK definitions appear in DEF my $safe_stack_def = 0; my @known_platforms = ( "__FreeBSD__", "VMS", "WIN16", "WIN32", "WINNT", "PERL5", "NeXT" ); my @known_algorithms = ( "RC2", "RC4", "RC5", "IDEA", "DES", "BF", "CAST", "MD2", "MD4", "MD5", "SHA", "RIPEMD", "MDC2", "RSA", "DSA", "DH", "HMAC", "FP_API" ); my $options=""; open(IN,") { $options=$1 if (/^OPTIONS=(.*)$/); } close(IN); # The following ciphers may be excluded (by Configure).
