Data-oriented pass on the encode hot path. Profiling showed bounds checks already elided by -o:speed; the cost was per-instruction loop/scan machinery and immediates falling off the hint path. - Gather the immediate slot in the single resolve pass and emit it straight- line (no scan over enc.enc); likewise drive the legacy REX prefix from the precomputed reg/mr/opr slots instead of a per-form scan. - Fold the separate needs_66 (GPR16) and SPL/BPL/SIL/DIL operand loops into the resolve pass, so user operands are visited exactly once. This was the big one: mov r,r 27 -> 21 ns. - Gate the whole legacy-prefix block on a single flags!=0 test (a legacy prefix is almost always absent) instead of four branches per instruction. - Make immediate forms hintable. A typed immediate builder names its width (inst_add_r32_imm32), the matcher already keys off the operand's declared size, so baking the form is byte-identical AND drops immediates from the full match scan: mov r32,imm32 55.7 -> 17.8 ns (3.1x). Floor (no-op) 14.55 -> 10.3 ns; realistic immediate-heavy typed mix 30 -> 20.5 ns/inst (~49 M inst/s). gen/builders/check/test/idempotent green; 2282 cases (typed==generic byte-identical, incl. the new immediate cases).

The Odin Programming Language
Odin is a general-purpose programming language with distinct typing, built for high performance, modern systems, and built-in data-oriented data types. The Odin Programming Language, the C alternative for the joy of programming.
