[PATCH 0/2] target/s390x: Fix R[NOX]SBG with T=1

Posted by Ilya Leoshkevich 1 year, 1 month ago

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
