Also, use 1/0 intead of h/l (e.g. a1 instead of ah), as this keeps consistency with other primitives and allows for naming that works with double word, triple word and quadruple word inputs/outputs.

Call this from the three places that currently implement this themselves. This is implemented with some slight indirection, which allows for per architecture implementations, replacing the define/macro tangle, which messes with variables that are not passed to it. Also remove a duplicate of bn_div_words() for the BN_ULLONG && BN_DIV2W case - this is already handled. ok tb@ 2023-01-23T12:17:58+00:00 jsing 2023-01-23T12:17:58+00:00 urn:sha1:c1cecd93e8ee9b8f82eb8dd7e752b256b5a9caf8 These are wrapped with #ifndef HAVE_BN_ADD_MUL_WORDS/HAVE_BN_MUL_WORDS, which are defined for architectures that provide their own assembly versions. 2023-01-23T12:09:06+00:00 jsing 2023-01-23T12:09:06+00:00 urn:sha1:59011d19bae2f06c7da3b93b0f376d59914113a2 This is wrapped with #ifndef HAVE_BN_SQR_WORDS, which is then defined for architectures that provide their own assembly versions. 2023-01-23T12:02:48+00:00 jsing 2023-01-23T12:02:48+00:00 urn:sha1:f19c47039da4275e5bf41ae120247544333dd021 This is wrapped with #ifndef HAVE_BN_DIV_WORDS, which are defined for architectures that provide their own assembly versions. 2023-01-23T10:31:03+00:00 jsing 2023-01-23T10:31:03+00:00 urn:sha1:72c06ed66b15060f591b12db9516011124121c3c These are wrapped with #ifndef HAVE_BN_ADD_WORDS/HAVE_BN_SUB_WORDS, which are defined for architectures that provide their own assembly versions. 2023-01-20T17:31:52+00:00 jsing 2023-01-20T17:31:52+00:00 urn:sha1:b92d9703cbe79988537ce70eae887ac8dd689362 Wrap these in HAVE_BN_{MUL,SQR}_COMBA{4,8} defines.
