3des: add amd64 assembly implementation for 3DES
* cipher/Makefile.am: Add 'des-amd64.S'. * cipher/cipher-selftests.c (_gcry_selftest_helper_cbc) (_gcry_selftest_helper_cfb, _gcry_selftest_helper_ctr): Handle failures from 'setkey' function. * cipher/cipher.c (_gcry_cipher_open_internal) [USE_DES]: Setup bulk functions for 3DES. * cipher/des-amd64.S: New file. * cipher/des.c (USE_AMD64_ASM, ATTR_ALIGNED_16): New macros. [USE_AMD64_ASM] (_gcry_3des_amd64_crypt_block) (_gcry_3des_amd64_ctr_enc), _gcry_3des_amd64_cbc_dec) (_gcry_3des_amd64_cfb_dec): New prototypes. [USE_AMD64_ASM] (tripledes_ecb_crypt): New function. (TRIPLEDES_ECB_BURN_STACK): New macro. (_gcry_3des_ctr_enc, _gcry_3des_cbc_dec, _gcry_3des_cfb_dec) (bulk_selftest_setkey, selftest_ctr, selftest_cbc, selftest_cfb): New functions. (selftest): Add call to CTR, CBC and CFB selftest functions. (do_tripledes_encrypt, do_tripledes_decrypt): Use TRIPLEDES_ECB_BURN_STACK. * configure.ac [host=x86-64]: Add 'des-amd64.lo'. * src/cipher.h (_gcry_3des_ctr_enc, _gcry_3des_cbc_dec) (_gcry_3des_cfb_dec): New prototypes.
Add non-parallel functions for small speed-up and 3-way parallel functions for
modes of operation that support parallel processing.
