Remove various defines that only existed for md32_common.h usage. 2023-08-11T15:25:36+00:00 jsing 2023-08-11T15:25:36+00:00 urn:sha1:e5c37e5e9f9d7f447090e5f144afac1bcc9341d9 Replace macros with static inline functions, as well as writing out the variable rotations instead of trying to outsmart the compiler. Also pull the message schedule update up and complete it prior to commencement of the round. Also use rotate right, rather than transposed rotate left. Overall this is more readable and more closely follows the specification. On some platforms (e.g. aarch64) there is no noteable change in performance, while on others there is a significant improvement (more than 25% on arm). ok miod@ tb@ 2023-08-10T07:15:23+00:00 jsing 2023-08-10T07:15:23+00:00 urn:sha1:13ecebf7d6c58d65f6df008731bbb41f4c2be2f6 This is a hack that is only enabled on a handful of 64 bit platforms, as a workaround for poor compiler optimisation. If you're running an archiac compiler on an archiac architecture, then you can deal with slightly lower performance. ok tb@ 2023-07-08T12:24:10+00:00 beck 2023-07-08T12:24:10+00:00 urn:sha1:f46ac389a5f2c573c854a6c2b50156ca974ea892 ok tb@ 2023-07-08T07:58:25+00:00 jsing 2023-07-08T07:58:25+00:00 urn:sha1:b73d110b33338f5dd55f8edf8a6c9a557c4c5d06 2023-07-08T07:52:25+00:00 jsing 2023-07-08T07:52:25+00:00 urn:sha1:51192ea4c1ff26a1f6ae8dab8e9bb1f465c01aaa 2023-07-08T07:49:45+00:00 jsing 2023-07-08T07:49:45+00:00 urn:sha1:a8e05970851a5ad651999ea1a9e8216dd8f3d06e No change to generated assembly. 2023-07-08T07:43:44+00:00 jsing 2023-07-08T07:43:44+00:00 urn:sha1:69c2702dd169f2187e540d7feaec5a0dabbcaaa3 No functional change. 2023-07-08T07:08:11+00:00 jsing 2023-07-08T07:08:11+00:00 urn:sha1:ed40d3cca6345815b45a8b09197f9d7d29369445 2023-07-07T15:09:45+00:00 jsing 2023-07-07T15:09:45+00:00 urn:sha1:22c789d71b31efbf40ba30721eb7379bb92a2600 Copy the update, transform and final functions from md32_common.h, manually expanding the macros for SHA1. This will allow for further clean up to occur. No change in generated assembly.
