How far should we trust ChangeLog attribution dates?

The 'changelogs' command of reposugeon attempts to fill in author attributions (author and authorship date) by mining Changelogs. It makes use of the fact that changesets often contain a change band for a Changelog and that change band normally contains or can be referred to exactly one attributio

I have implemented the ability for an email address to be declared as an alias in an author map file. When this is done, that alias will be recognized in ChangeLog attributions and mapped back to the base address for which it is an alias when filling inm Author attributions. However, the timezon

So, both AVR and RISC-V are fairly register-rich with usually 32. RV32E only has 16, but that's still a lot better than i386. If you use a lot of 16 bit integers then AVR also only has effectively 16 registers (or a more with a mix of 8 and 16 bit variables). 32 bit integers should be rare in AVR c
