It’s always quite difficult in these releases to help express to people exactly
what’s happened. We’ve got over 1000 changesets — what have we been doing? If
my star chart is correct, the latter represents nearly 1700 extra lines of
codes in tools/tests/x86_emulator/predicates.c. It’s actually a reasonable
chunk of code churn, which I think is worth highlighting.
Re the former, I think letting someone know that a new instruction is emulated
is worthwhile.
Ian is the maintainer, so ultimately I think it’s his call?
