Struct PreDecodedInst 

pub struct PreDecodedInst {
    pub opcode: Opcode,
    pub args: Args,
    pub pc: u32,
    pub next_pc: u32,
    pub gas_cost: u32,
    pub is_gas_block_start: bool,
    pub ra: u8,
    pub rb: u8,
    pub rd: u8,
}

Pre-decoded PVM instruction. Stores everything the codegen and the gas simulator need per instruction.

Fields

opcode: Opcode

PVM opcode (for compile_instruction match dispatch).

args: Args

Decoded arguments (registers, immediates, offsets).

pc: u32

PVM byte offset of this instruction.

next_pc: u32

PVM byte offset of the next instruction.

gas_cost: u32

Gas cost if this is a gas block start (>0), 0 otherwise. Set by the recompiler’s single-pass codegen via placeholder + patch.

is_gas_block_start: bool

Whether this instruction starts a gas metering block.

ra: u8

Flat register fields for fast gas cost lookup (avoids Args enum match).

rb: u8

rd: u8
