Abstract
The increasing use of digital signal processors (DSPs) and application specific instruction-set processors (ASIPs) has put a strain on the perceived mature state of compiler technology. The presence of custom hardware for application-specific needs has introduced instruction types which are unfamiliar to the capabilities of traditional compilers. Thus, these traditional techniques can lead to inefficient and sparsely compacted machine microcode. In this paper, we introduce a novel instruction-set matching and selection methodology, based upon a rich representation useful for DSP and mixed control-oriented applications. This representation shows explicit behaviour that references architecture resource classes. This allows a wide range of instructions types to be captured in a pattern set. The pattern set has been organized in a manner such that matching is extremely efficient and retargeting to architectures with new instruction sets is well defined. The matching and selection algorithms have been implemented in a retargetable code generation system called CodeSyn.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
