Instruction Encoding and Format Families: Pitfalls and Red Flags

Pitfalls and red flags

Pitfalls and Red Flags for Instruction Encoding and Format Families is anchored on Decode critical-path depth, immediate-generation logic complexity, and illegal-instruction detection coverage.. 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.
