11-post thread. Root: 4-byte overhead interpreter with 64KiB aligned
window of directly-jumpable words (write to ax doesn't change other
48 bits), cuts source size in half. Tangent with @noop_dev covering
cold-cache misses, runtime-macroassembler idea, 4K Atari 2600 emu
precedent. End: GPU code generation for AMD where 8+ bitfields in
an opcode means the simple interpreter won't work.
