Also, some operating systems (for example VMS with VAX C) 18# need to keep track of the global variables as well as the functions. 19# 20# So, a remake of this script is done so as to include information on the 21# kind of symbol it is (function or variable) and what algorithms they're 22# part of. This will allow easy translating to .def files or the corresponding 23# file in other operating systems (a .opt file for VMS, possibly with a .mar 24# file). 25# 26# The format now becomes: 27# 28# routine-name nnnn info 29# 30# and the "info" part is actually a colon-separated string of fields with 31# the following meaning: 32# 33# existence:platform:kind:algorithms 34# 35# - "existence" can be "EXIST" or "NOEXIST" depending on if the symbol is 36# found somewhere in the source, 37# - "platforms" is empty if it exists on all platforms, otherwise it contains 38# comma-separated list of the platform, just as they are if the symbol exists 39# for those platforms, or prepended with a "!" if not. This helps resolve 40# symbol name variants for platforms where the names are too long for the 41# compiler or linker, or if the systems is case insensitive and there is a 42# clash, or the symbol is implemented differently (see 43# EXPORT_VAR_AS_FUNCTION). This script assumes renaming of symbols is found 44# in the file crypto/symhacks.h. 45# The semantics for the platforms is that every item is checked against the 46# environment. For the negative items ("!FOO"), if any of them is false 47# (i.e. "FOO" is true) in the environment, the corresponding symbol can't be 48# used. For the positive itms, if all of them are false in the environment, 49# the corresponding symbol can't be used. Any combination of positive and 50# negative items are possible, and of course leave room for some redundancy. 51# - "kind" is "FUNCTION" or "VARIABLE". The meaning of that is obvious. 52# - "algorithms" is a comma-separated list of algorithm names. This helps 53# exclude symbols that are part of an algorithm that some user wants to 54# exclude. 55# 56 57my $debug=0; 58 59my $crypto_num= "util/libeay.num"; 60my $ssl_num= "util/ssleay.num"; 61my $libname; 62 63my $do_update = 0; 64my $do_rewrite = 1; 65my $do_crypto = 0; 66my $do_ssl = 0; 67my $do_ctest = 0; 68my $do_ctestall = 0; 69my $do_checkexist = 0; 70 71my $VMSVAX=0; 72my $VMSAlpha=0; 73my $VMS=0; 74my $W32=0; 75my $W16=0; 76my $NT=0; 77my $OS2=0; 78# Set this to make typesafe STACK definitions appear in DEF 79my $safe_stack_def = 0; 80 81my @known_platforms = ( "__FreeBSD__", "PERL5", "NeXT", 82 "EXPORT_VAR_AS_FUNCTION" ); 83my @known_ossl_platforms = ( "VMS", "WIN16", "WIN32", "WINNT", "OS2" ); 84my @known_algorithms = ( "RC2", "RC4", "RC5", "IDEA", "DES", "BF", 85 "CAST", "MD2", "MD4", "MD5", "SHA", "SHA0", "SHA1", 86 "RIPEMD", 87 "MDC2", "RSA", "DSA", "DH", "EC", "HMAC", "AES", 88 # Envelope "algorithms" 89 "EVP", "X509", "ASN1_TYPEDEFS", 90 # Helper "algorithms" 91 "BIO", "COMP", "BUFFER", "LHASH", "STACK", "ERR", 92 "LOCKING", 93 # External "algorithms" 94 "FP_API", "STDIO", "SOCK", "KRB5", "ENGINE", "HW" ); 95 96my $options=""; 97open(IN,"<Makefile.ssl") || die "unable to open Makefile.ssl!\n"; 98while(<IN>) { 99 $options=$1 if (/^OPTIONS=(.*)$/); 100} 101close(IN); 102 103# The following ciphers may be excluded (by Configure).
