Struct DecodedInst 

pub struct DecodedInst {
    pub opcode: Opcode,
    pub ra: u8,
    pub rb: u8,
    pub rd: u8,
    pub imm1: u64,
    pub imm2: u64,
    pub pc: u32,
    pub next_pc: u32,
    pub next_idx: u32,
    pub target_idx: u32,
    pub bb_gas_cost: u32,
}

Pre-decoded instruction for the fast interpreter / JIT path.

Flattened representation: all operands stored directly (no enum discrimination at runtime). 40 bytes.

Fields

opcode: Opcode

ra: u8

Register A (first register operand, context-dependent).

rb: u8

Register B (second register operand, context-dependent).

rd: u8

Register D (destination register, context-dependent).

imm1: u64

First immediate / offset value.

imm2: u64

Second immediate / offset value.

pc: u32

Byte offset of this instruction in the code.

next_pc: u32

Byte offset of the next sequential instruction.

next_idx: u32

Pre-resolved instruction index for the next sequential instruction.

target_idx: u32

Pre-resolved instruction index for the branch/jump target. u32::MAX = invalid (out-of-program target).

bb_gas_cost: u32

Gas cost to charge at gas-block entry (0 for non-gas-block-start instructions). Gas blocks = {PC=0} ∪ {post-terminator PCs}; branch targets are NOT gas-block starts.
