loop snippet

Concept

In OTBN random instruction generator (`otbn-rig`), a loop snippet is a kind of snippet used to build a generated program. The documentation says snippets form a tree in the generator’s JSON output and lists loops alongside other more complex snippet forms, but it does not describe loop-specific structure or sizing rules in the provided evidence.

loop snippet

In otbn-rig, a loop snippet is a kind of snippet used when generating a random OTBN program. The documentation says the generated program is built from blocks called snippets, and that more complicated snippets include conditional branches and loops. The JSON output format represents this as a tree of snippets.

The documentation also describes snippet size in general. It gives examples for a single unconditionally executed instruction, a straight-line sequence of instructions, and an if/else branch. However, the provided evidence does not define any loop-specific size formula or JSON structure.
