VFP rounding modes / exception flags

Priority 1 - CPU Architectures & Execution Engines / 1.4 AArch32 (A32 + T32), NEON, VFP

As a firmware developer, I want vemu to finish its VFP rounding modes / exception flags model, so that I can depend on numerically-exact FP for production firmware, not just the common path.

Why it matters

Numerically-exact FP

Summary

Non-default rounding, FP exceptions

Scope of work

Partially modeled. Complete the missing mechanics of VFP rounding modes / exception flags. What it is: Non-default rounding, FP exceptions. Why it matters: Numerically-exact FP.

Current state

Status: Partially implemented. Notes / evidence: Host path = round-nearest, flags discarded.

Blocked by 1

Fund these first - this work can't be completed until they ship.
