- BN_LLONG use 'unsigned long long' in
- some bignum calculations.
- This has no value when
- SIXTY_FOUR_BIT or
- SIXTY_FOUR_BIT_LONG is given.
- RC4_CHAR makes the basic RC4 unit of
- calculation an unsigned char.
- SIXTY_FOUR_BIT processor registers
- are 64 bits, long is
- 32 bits, long long is
- 64 bits.
- SIXTY_FOUR_BIT_LONG processor registers
- are 64 bits, long is
- 64 bits.
- THIRTY_TWO_BIT processor registers
- are 32 bits.
- EXPORT_VAR_AS_FN for shared libraries,
- export vars as
- accessor functions.
-
- apps_extra_src => Extra source to build apps/openssl, as
- needed by the target.
- cpuid_asm_src => assembler implementation of cpuid code as
- well as OPENSSL_cleanse().
- Default to mem_clr.c
- bn_asm_src => Assembler implementation of core bignum
- functions.
- Defaults to bn_asm.c
- ec_asm_src => Assembler implementation of core EC
- functions.
- des_asm_src => Assembler implementation of core DES
- encryption functions.
- Defaults to 'des_enc.c fcrypt_b.c'
- aes_asm_src => Assembler implementation of core AES
- functions.
- Defaults to 'aes_core.c aes_cbc.c'
- bf_asm_src => Assembler implementation of core BlowFish
- functions.
- Defaults to 'bf_enc.c'
- md5_asm_src => Assembler implementation of core MD5
- functions.
- sha1_asm_src => Assembler implementation of core SHA1,
- functions, and also possibly SHA256 and
- SHA512 ones.
- cast_asm_src => Assembler implementation of core CAST
- functions.
- Defaults to 'c_enc.c'
- rc4_asm_src => Assembler implementation of core RC4
- functions.

- functions.
- rc5_asm_src => Assembler implementation of core RC5
- functions.
- Defaults to 'rc5_enc.c'
- wp_asm_src => Assembler implementation of core WHIRLPOOL
- functions.
- cmll_asm_src => Assembler implementation of core CAMELLIA
- functions.
- Defaults to 'camellia.c cmll_misc.c cmll_cbc.c'
- modes_asm_src => Assembler implementation of cipher modes,
- currently the functions gcm_gmult_4bit and
- gcm_ghash_4bit.
- padlock_asm_src => Assembler implementation of core parts of
- the padlock engine. This is mandatory on
- any platform where the padlock engine might
- actually be built.
