Add Camellia AES-NI/AVX2 implementation
* cipher/Makefile.am: Add 'camellia-aesni-avx2-amd64.S'.
* cipher/camellia-aesni-avx2-amd64.S: New file.
* cipher/camellia-glue.c (USE_AESNI_AVX2): New macro.
(CAMELLIA_context) [USE_AESNI_AVX2]: Add 'use_aesni_avx2'.
[USE_AESNI_AVX2] (_gcry_camellia_aesni_avx2_ctr_enc)
(_gcry_camellia_aesni_avx2_cbc_dec)
(_gcry_camellia_aesni_avx2_cfb_dec): New prototypes.
(camellia_setkey) [USE_AESNI_AVX2]: Check AVX2+AES-NI capable hardware
and set 'ctx->use_aesni_avx2'.
(_gcry_camellia_ctr_enc) [USE_AESNI_AVX2]: Add AVX2 accelerated code.
(_gcry_camellia_cbc_dec) [USE_AESNI_AVX2]: Add AVX2 accelerated code.
(_gcry_camellia_cfb_dec) [USE_AESNI_AVX2]: Add AVX2 accelerated code.
(selftest_ctr_128, selftest_cbc_128, selftest_cfb_128): Grow 'nblocks'
so that AVX2 codepaths get tested.
* configure.ac (camellia) [avx2support, aesnisupport]: Add
'camellia-aesni-avx2-amd64.lo'.
--
Add new AVX2/AES-NI implementation of Camellia that processes 32 blocks in
parallel.
Speed old (AVX/AES-NI) vs. new (AVX2/AES-NI) on Intel Core i5-4570:
ECB/Stream CBC CFB OFB CTR
