Subject: [RFC PATCH 0/3] target/ppc: Change CR registers from i32 to tl
Date: Wed, 13 Sep 2023 10:58:11 +1000 [thread overview]
Message-ID: <20230913005814.413113-1-npiggin@gmail.com> (raw)
This is a bit of churn so I might leave it for later in the cycle (or
defer if we get a lot of other changes) since it's a relatively
mechanical change. So don't spend time reviewing details, I'm just
wondering about concept and general approach.
I'm not sure the history of why these are 32-bit, maybe better code gen
on 32-bit host emulating 64-bit? If so, that shouldn't be so important
now that most people use 64-bit systems to develop and test with.
Thanks,
Nick
