There is no intention to expose these via public API or to use them in TLS.
For now these will only be used for short-circuiting pointless expensive
computations in DH_check().

libcrypto: make most of the BN_* macro pollution internal2025-12-05T14:12:32+00:00tb2025-12-05T14:12:32+00:00urn:sha1:f3f05f0cf8c30a990193e332e26fdd8e54b3f59b
This is a first sweep of reducing the number of terribly named macros
in bn.h More can go away. Those we need internally go to bn_local.h.
Annoyingly bn_internal.h uses some of them, so it includes bn_local.h
now. This can be cleaned up later.

Re-enable bn_sqr_words() assembly.2025-09-07T05:21:29+00:00jsing2025-09-07T05:21:29+00:00urn:sha1:9283c4361ce1f1a39a1f03c588c3d1a3da64025e
This is now only on amd64.
Disable assembly bn_sqr_words() again for now.2025-09-02T14:18:38+00:00jsing2025-09-02T14:18:38+00:00urn:sha1:99f066b0e074e44bab8174651b96c62ac333cc64
The old assembly bn_sqr_words() does not actually square words in the
bignum sense. These will have to be renamed (once I come up with a name
for whatever it actually does) before we can roll forward again.
Found the hard way by Janne Johansson.
Constify bn_mul_words().2025-09-01T15:33:23+00:00jsing2025-09-01T15:33:23+00:00urn:sha1:edd4db8b24106490f82c1a694d4e2b35afe9c6cbRename prototype for bn_mul_normal().2025-08-31T09:33:30+00:00jsing2025-08-31T09:33:30+00:00urn:sha1:faea853ea68887727c76f113f0487e95e8aa0738
This was missed in the previous commit.
Rename bn_mul_words()/bn_mul_add_words().2025-08-30T07:54:27+00:00jsing2025-08-30T07:54:27+00:00urn:sha1:694b88dc8ad458db9997e90128806a423fec09db
Most bn_.*_words() functions operate on two word arrays, however
bn_mul_words() and bn_mul_add_words() operate on one word array and
multiply by a single word. Rename these to bn_mulw_words() and
bn_mulw_add_words() to reflect this, following naming scheme that we use
for primitives.
This frees up bn_mul_words() to actually be used for multiplying two word
arrays. Rename bn_mul_normal() to bn_mul_words(), which will then become
one of the possible assembly integration points.

Rework bn_sqr() to use bn_sqr_words().2025-08-30T07:16:06+00:00jsing2025-08-30T07:16:06+00:00urn:sha1:3adccdb355e2f651255227b11a6324730cb85e48
Rework some of the squaring code so that it calls bn_sqr_words() and use
this as the integration point for assembly. Convert bn_sqr_normal() to
bn_sqr_words(), which is then used on architectures that do not provide
their own version.
This means that we resume using the assembly version of bn_sqr_words() on
i386, mips64 and powerpc, which can provide considerable performance gains.

Provide bn_sqr_comba6().2025-08-05T15:08:13+00:00jsing2025-08-05T15:08:13+00:00urn:sha1:85ada1d50506ca1df60943a83591a12c2f5804fa
This allows for fast squaring of a 6 word array.
