v1: https://lists.gnu.org/archive/html/qemu-devel/2023-10/msg10251.html v1 -> v2: Introduce op_laa_addu64() (Richard). Add the ADD LOGICAL WITH CARRY test. This was intended to catch the issue mentioned by David, but did not succeed. I thought it would still be worthwile to include it as a regression test.
Hi, This series fixes two issues with updating CC. David was suggesting a bigger rewrite [1], but I did not dare do this (yet). Instead, these are targeted fixes: patch 1 helps with installing Fedora, and patch 3 addresses something I noticed when reviewing the code. Patches 2, 4 and 5 are tests.
