The fxam implementation does not check for invalid encodings, instead treating them like NaN or normal numbers depending on the exponent. Fix it to check that the high bit of the significand is set before treating an encoding as NaN or normal, thus resulting in correct handling (all of C0, C2 and C3 cleared) for invalid encodings. Backports commit 34b9cc076ff423023a779a04a9f7cd7c17372cbf from qemu |
