How much does it bother you if THead CPUs C906/C910 e.g. in Milk-V Pioneer never set the FP sticky flags inexact, underflow, overflow, divide by zero, invalid?

This appears to be documented in the manual, while also claiming to be “Fully IEEE-754 compliant”. But FP exception flags are NOT optional.
