[PATCH 0/2] target/s390x: Fix the floating-point multiply-and-add NaN rules

[Ilya Leoshkevich]

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
