+ 2020-11-07  Niels Möller  <nisse@lysator.liu.se>
+ 
++	Merged initial powerpc64 implementation of chacha.
+ 	* configure.ac: New command line option --enable-power-altivec.
+ 	Update asm_path logic, and add altivec to FAT_TEST_LIST.
+ 	* fat-ppc.c (get_ppc_features): Add logic to check for altivec and
+ 	vsx support, and select aither C or altivec implementation of
+ 	chacha_core.
 -	* powerpc64/fat/chacha-core-internal-2.asm: New file.
++	* powerpc64/p7/chacha-core-internal.asm: New file.
+ 
+ 2020-09-25  Niels Möller  <nisse@lysator.liu.se>
+ 
+ 	* powerpc64/p7/chacha-core-internal.asm: New file.
+ 	* Makefile.in (distdir): Add powerpc64/p7.
+ 
 +2020-10-29  Niels Möller  <nisse@lysator.liu.se>
 +
 +	* blowfish.c (blowfish_set_key): Add casts to uint32_t. Avoids
 +	undefined behavior, since shifting an 8-bit value left by 24 bits
 +	overflows the range of signed int. Reported by Guido Vranken.
 +
 +2020-10-28  Niels Möller  <nisse@lysator.liu.se>
 +
 +	* gmp-glue.h (cnd_add_n, cnd_sub_n, cnd_swap): Deleted, use
 +	corresponding functions mpn_cnd_add_n, mpn_cnd_sub_n,
 +	mpn_cnd_swap, available from GMP version 6.1.0. Update all
 +	callers, in particular, mpn_cnd_add_n and mpn_cnd_sub_n has one
 +	more argument than the old functions.
 +
 +	* gmp-glue.c (mpn_cnd_add_n, mpn_cnd_sub_n, mpn_cnd_swap)
 +	[NETTLE_USE_MINI_GMP]: Fallback definitions or mini-gmp builds.
 +
 +2020-10-14  Niels Möller  <nisse@lysator.liu.se>
 +
 +	* ecc-mod-arith.c (ecc_mod_pow_2k, ecc_mod_pow_2k_mul): Moved
 +	functions here.
 +	* ecc-internal.h (ecc_mod_pow_2kp1): New macro, calling the more
 +	general ecc_mod_pow_2k_mul.
 +	* ecc-curve25519.c (ecc_mod_pow_2kp1): Deleted static function.
 +	* ecc-curve448.c (ecc_mod_pow_2k, ecc_mod_pow_2kp1): Deleted
 +	static functions.
 +
 +2020-10-13  Niels Möller  <nisse@lysator.liu.se>
 +
 +	* ecc-mod-inv.c (ecc_mod_inv_destructive): New helper function,
 +	not preserving input argument. Extracted from old ecc_mod_inv.
 +	(ecc_mod_inv): Call ecc_mod_inv_destructive.
 +	(ecc_mod_inv_redc): New inversion function, with input and output
 +	in redc form.
 +
 +	* ecc-secp224r1.c: Select between ecc_mod_inv and ecc_mod_inv_redc.
 +	* ecc-secp256r1.c: Likewise.
 +
 +	* ecc-j-to-a.c (ecc_j_to_a): Simplify redc-related logic, taking
 +	advantage of ecc->p.invert handling redc, when appropriate. Reduce
 +	scratch need from 5n to 4n in the process (assuming inversion
 +	needs 2n).
 +
 +	* testsuite/ecc-modinv-test.c (ref_modinv): Updated to do redc, if
 +	appropriate.
 +
 +2020-09-25  Niels Möller  <nisse@lysator.liu.se>
 +
  	* gcm.c (gcm_fill): Added separate implementations for big- and
  	little-endian, to use uint64_t stores and less overhead.
