[PATCH 00/10] tcg/s390x: updates for mie2 and mie3

Posted by Richard Henderson 3 years, 11 months ago

While reviewing David Miller's updates for mie3 for target/s390x,
I realized that most of those are useful on the code generation
side as well.  Then I stepped back and looked at what other
feature extensions had been missed.

Our new s390x ci host is a z15, so this new code gets exercised,
at least minimally.  I need to get some other bits configured to
do more comprehensive testing, e.g. avocado and risu.  But in the
meantime...
