Subject: [PATCH 0/2] target/s390x: Fix the floating-point multiply-and-add NaN rules
Date: Wed, 23 Oct 2024 01:59:17 +0200 [thread overview]
Message-ID: <20241023000147.34035-1-iii@linux.ibm.com> (raw)
Hi,
Peter reported on IRC that FMA NaN handling was likely broken on s390x.
Patch 1 of this series fixes the issue, patch 2 adds a test. For the
sake of readability, the test sacrifices the 90-character line length
rule.
Best regards,
Ilya
