openssl/Configure
Richard Levitte 96d2d7bc71 Use Configure's @disablables and %disabled through configdata.pm 
Enhances the routines in OpenSSL::Test::Utils for checking disabled
stuff to get their information directly from Configure instead of
'openssl list -disabled'.

#
# --config add the given configuration file, which will be read after
# any "Configurations*" files that are found in the same

# --prefix prefix for the OpenSSL installation, which includes the
# directories bin, lib, include, share/man, share/doc/openssl
# This becomes the value of INSTALLTOP in Makefile
# (Default: /usr/local)
# --openssldir OpenSSL data area, such as openssl.cnf, certificates and keys.
# If it's a relative directory, it will be added on the directory
# given with --prefix.
# This becomes the value of OPENSSLDIR in Makefile and in C.
# (Default: PREFIX/ssl)
#
# --install_prefix Additional prefix for package builders (empty by
# default). This needn't be set in advance, you can
# just as well use "make INSTALL_PREFIX=/whatever install".
#
# --cross-compile-prefix Add specified prefix to binutils components.
#
# --api One of 0.9.8, 1.0.0 or 1.1.0. Do not compile support for
# interfaces deprecated as of the specified OpenSSL version.
#
# no-hw-xxx do not compile support for specific crypto hardware.
# Generic OpenSSL-style methods relating to this support
# are always compiled but return NULL if the hardware
# support isn't compiled.
# no-hw do not compile support for any crypto hardware.
# [no-]threads [don't] try to create a library that is suitable for
# multithreaded applications (default is "threads" if we
# know how to do it)
# [no-]shared [don't] try to create shared libraries when supported.
# no-asm do not use assembler
# no-dso do not compile in any native shared-library methods. This
# will ensure that all methods just return NULL.
# no-egd do not compile support for the entropy-gathering daemon APIs
# [no-]zlib [don't] compile support for zlib compression.
# zlib-dynamic Like "zlib", but the zlib library is expected to be a shared
# library and will be loaded in run-time by the OpenSSL library.
# sctp include SCTP support
# 386 generate 80386 code
# no-sse2 disables IA-32 SSE2 code, above option implies no-sse2
# no-<cipher> build without specified algorithm (rsa, idea, rc5, ...)
# -<xxx> +<xxx> compiler options are passed through
#
# DEBUG_SAFESTACK use type-safe stacks to enforce type-safety on stack items
# provided to stack calls. Generates unique stack functions for
# each possible stack type.
# DES_PTR use pointer lookup vs arrays in the DES in crypto/des/des_locl.h
# DES_RISC1 use different DES_ENCRYPT macro that helps reduce register
# dependancies but needs to more registers, good for RISC CPU's
# DES_RISC2 A different RISC variant.
# DES_UNROLL unroll the inner DES loop, sometimes helps, somtimes hinders.
# DES_INT use 'int' instead of 'long' for DES_LONG in crypto/des/des.h
# This is used on the DEC Alpha where long is 8 bytes
# and int is 4
# BN_LLONG use the type 'long long' in crypto/bn/bn.h
# MD2_CHAR use 'char' instead of 'int' for MD2_INT in crypto/md2/md2.h
# MD2_LONG use 'long' instead of 'int' for MD2_INT in crypto/md2/md2.h
# IDEA_SHORT use 'short' instead of 'int' for IDEA_INT in crypto/idea/idea.h
# IDEA_LONG use 'long' instead of 'int' for IDEA_INT in crypto/idea/idea.h
# RC2_SHORT use 'short' instead of 'int' for RC2_INT in crypto/rc2/rc2.h
# RC2_LONG use 'long' instead of 'int' for RC2_INT in crypto/rc2/rc2.h
# RC4_CHAR use 'char' instead of 'int' for RC4_INT in crypto/rc4/rc4.h
# RC4_LONG use 'long' instead of 'int' for RC4_INT in crypto/rc4/rc4.h
# RC4_INDEX define RC4_INDEX in crypto/rc4/rc4_locl.h. This turns on
# array lookups instead of pointer use.
# RC4_CHUNK enables code that handles data aligned at long (natural CPU
# word) boundary.
# RC4_CHUNK_LL enables code that handles data aligned at long long boundary
# (intended for 64-bit CPUs running 32-bit OS).
# BF_PTR use 'pointer arithmatic' for Blowfish (unsafe on Alpha).
# BF_PTR2 intel specific version (generic version is more efficient).

# Following are set automatically by this script

# MD5_ASM use some extra md5 assember,
