Subject: [PATCH v2 0/2] target/s390x: Fix R[NOX]SBG with T=1
Date: Thu, 16 Mar 2023 00:56:40 +0100 [thread overview]
Message-ID: <20230315235642.118002-1-iii@linux.ibm.com> (raw)
v1: https://lists.gnu.org/archive/html/qemu-devel/2023-03/msg04493.html
v1 -> v2: Work around a clang issue (Thomas).
Add cc=0 test, use more human-friendly constants.
Hi,
This series fixes ROTATE THEN <do something with> SELECTED BITS when
test-results control is on. The problem is the incorrect translation,
which confuses the register allocator.
Patch 1 is the fix, patch 2 adds a test.
Best regards,
Ilya
