Fixture 80

trie

C · 2 functions · 4 lanes · 8 of 8 function-lanes behave identically

All 4 lanes recompile and return the same results as the original.

A four-way prefix tree over a flat node array (symbols 'a'..'d'). Children are indices, not pointers, so insertion allocates by bumping a cursor and lookup is a chain of dependent loads -- pointer-chasing without a heap.
