Branch Handling, Pipeline Flush, and Redirect Timing: Pitfalls and Red Flags
Pitfalls and Red Flags for Branch Handling, Pipeline Flush, and Redirect Timing.
Pitfalls and red flags
Pitfalls and Red Flags for Branch Handling, Pipeline Flush, and Redirect Timing is anchored on Branch mispredict penalty in cycles, wrong-path retire count (target zero), and redirect latency from resolve to fetch restart.. Convert observations into mechanism-backed decisions with explicit ownership.
Tuning knobs without proving first failing mechanism.
Ignoring privilege, trap, and memory-protection side effects.
Mixing extension profiles across benchmark runs.
Shipping on one benchmark uplift without stress replay.
