Also, some operating systems (for example VMS with VAX C) 181556Srgrimes# need to keep track of the global variables as well as the functions. 191556Srgrimes# 201556Srgrimes# So, a remake of this script is done so as to include information on the 211556Srgrimes# kind of symbol it is (function or variable) and what algorithms they're 221556Srgrimes# part of. This will allow easy translating to .def files or the corresponding 231556Srgrimes# file in other operating systems (a .opt file for VMS, possibly with a .mar 241556Srgrimes# file). 251556Srgrimes# 261556Srgrimes# The format now becomes: 271556Srgrimes# 281556Srgrimes# routine-name nnnn info 291556Srgrimes# 301556Srgrimes# and the "info" part is actually a colon-separated string of fields with 311556Srgrimes# the following meaning: 321556Srgrimes# 331556Srgrimes# existence:platform:kind:algorithms 341556Srgrimes# 351556Srgrimes# - "existence" can be "EXIST" or "NOEXIST" depending on if the symbol is 361556Srgrimes# found somewhere in the source, 371556Srgrimes# - "platforms" is empty if it exists on all platforms, otherwise it contains 3850471Speter# comma-separated list of the platform, just as they are if the symbol exists 391556Srgrimes# for those platforms, or prepended with a "!" if not. This helps resolve 401556Srgrimes# symbol name variants for platforms where the names are too long for the 411556Srgrimes# compiler or linker, or if the systems is case insensitive and there is a 421556Srgrimes# clash, or the symbol is implemented differently (see 4390108Simp# EXPORT_VAR_AS_FUNCTION). This script assumes renaming of symbols is found 4490108Simp# in the file crypto/symhacks.h. 4590108Simp# The semantics for the platforms is that every item is checked against the 4690108Simp# environment. For the negative items ("!FOO"), if any of them is false 4790108Simp# (i.e. "FOO" is true) in the environment, the corresponding symbol can't be 4890108Simp# used. For the positive itms, if all of them are false in the environment, 4990108Simp# the corresponding symbol can't be used. Any combination of positive and 5090108Simp# negative items are possible, and of course leave room for some redundancy. 5190108Simp# - "kind" is "FUNCTION" or "VARIABLE". The meaning of that is obvious. 5290108Simp# - "algorithms" is a comma-separated list of algorithm names. This helps 5390108Simp# exclude symbols that are part of an algorithm that some user wants to 5490108Simp# exclude. 5590108Simp# 561556Srgrimes 571556Srgrimesmy $debug=0; 581556Srgrimes 5990108Simpmy $crypto_num= "util/libeay.num"; 6089788Sgreenmy $ssl_num= "util/ssleay.num"; 6151208Sgreenmy $libname; 621556Srgrimes 6348051Sgreenmy $do_update = 0; 6451208Sgreenmy $do_rewrite = 1; 6551208Sgreenmy $do_crypto = 0; 6651208Sgreenmy $do_ssl = 0; 6751249Sgreenmy $do_ctest = 0; 6851208Sgreenmy $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 "SHA256", "SHA512", "RIPEMD", 87 "MDC2", "RSA", "DSA", "DH", "EC", "ECDH", "ECDSA", "HMAC", "AES", "CAMELLIA", 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", "DGRAM", 95 # Engines 96 "STATIC_ENGINE", "ENGINE", "HW", "GMP", 97 # Deprecated functions 98 "DEPRECATED" ); 99 100my $options=""; 101open(IN,"<Makefile") || die "unable to open Makefile!\n"; 102while(<IN>) { 103 $options=$1 if (/^OPTIONS=(.*)$/); 104} 105close(IN); 106 107# The following ciphers may be excluded (by Configure).
