Subject: [PATCH 0/2] target/s390x: Fix DR/D INT64_MIN / -1 host crash
Date: Tue, 14 Jul 2026 21:02:39 +0200 [thread overview]
Message-ID: <20260714190351.337923-1-iii@linux.ibm.com> (raw)
Hi,
Christian reported that INT64_MIN / -1 crashes the emulator itself
instead of the guest program. This series fixes the issue and adds a
test.
Best regards,
Ilya
