[PATCH v2 0/5] target/s390x: CC fixes

[Ilya Leoshkevich <iii@linux.ibm.com>]

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.

Best regards,
Ilya
