smaz_implementations-base_64: rewrite variable-length verbatim code

At some point in the development I changed the base-64 scheme, but failed to propagate it everywhere. Mostly I intend to use only one mode in base-64, and the other one is merely a place-holder, which explains how it got neglected. Now at least it works, even if it's useless. check-in: 210677c061 user: nat tags: trunk

2017-01-06
22:44

2016-12-28
22:29
smaz_implementations-base_64: fix reading of 3n+2 verbatim length

A sign error caused a direct constraint error, and using the wrong type caused overlong reads (now 4 is hardcoded just like it is in encoding code). check-in: 23d16059bd user: nat tags: trunk

2016-12-27
21:28

2016-12-16
20:55
smaz_generic: optimize compression

For some reason it seems even with -O3, calling Dict_Entry involves a string copy, which makes `memcpy` the larger time consumer of the copmpression algorithm. Inlining it manually improves performance a lot. check-in: 674fadc74b user: nat tags: trunk

2016-12-15
20:12
tools/smaz: use the new validation function instead of ad-hoc code check-in: 3a95d52c86 user: nat tags: trunk
2016-12-14
20:01
smaz_generic: brind the predicate back as a separate function

Since Smaz dictionaries are meant to be global hard-coded constant objects, it makes sense to check the precondition only once, e.g. in a test suite, and not for each and every subprogram call. check-in: ec19d3153c user: nat tags: trunk

22:09
