[Qemu-devel] [PATCH v4 0/3] target/s390x: implement loads/store quadword

[Aurelien Jarno]

This patchset implements the LOAD PAIR FROM QUADWORD and STORE PAIR TO
QUADWORD instructions. The corresponding patches have been in my previous
patchset and the pull request from Richard, but they failed to build on a
host without atomic128 support.

This new version fixes that. It has to be applied over the pull request
as it makes uses of the check_alignment function.

Finally the latest patch fixes a lack of alignement check in CDSG,
discovered as I used it as an example about how to properly handle hosts
without atomic128 support.

  target/s390x: implement LOAD PAIR FROM QUADWORD
  target/s390x: implement STORE PAIR TO QUADWORD
  target/s390x: check alignment in CDSG in the !CONFIG_ATOMIC128 case
