Stack-machine opcodes. The u8 / u32 payloads stay inline so the Vec<Op> is a flat array the interpreter scans linearly.

Variants

PushConst(u32)

Push consts[idx] onto the stack.

Pop

Drop the top of stack.

LoadHot(u8)

Push the value of hot slot idx (one of the HOT_* constants).

StoreHot(u8)

Pop and write into hot slot idx.

LoadQ(u8)

Push q-channel idx (0-based: LoadQ(0) → q1).

StoreQ(u8)

Pop and write into q-channel idx.

LoadCold(u32)

Push ctx.get(cold_names[idx]).unwrap_or(0.0).

StoreCold(u32)

Pop and call ctx.set(cold_names[idx], v).

IfSelect

MD2 if(cond, then, else) (and milkif) — if returns then when cond != 0, else else. The bytecode evaluates both branches and selects — same as evalexpr’s builtin if does.

Rand

rand(max) — pseudo-random value in [0, max) seeded by the system clock (matches the evalexpr-registered rand).

Gmegabuf

gmegabuf(idx) — read slot idx from the thread-local gmegabuf. Out-of-range / non-finite indices push 0.0.

Megabuf

megabuf(idx) — same shape as Gmegabuf against the megabuf.

GmegabufSet

gmegabuf_set(idx, val) — write val to slot idx. Pushes 0.0 (evalexpr returns Empty on assignments; the rest of the VM treats that as a numeric 0.0).

MegabufSet

megabuf_set(idx, val) — same shape as GmegabufSet against the megabuf.

Trait Implementations
