Struct Predecode 

pub struct Predecode {
    pub insts: Vec<RvPreDecodedInst>,
    pub block_costs: Vec<u32>,
    pub block_reserves: Vec<u32>,
    pub decode_error_at: Option<u32>,
}

Output of the predecode pass over an RV+C+custom-0 code section.

Fields

insts: Vec<RvPreDecodedInst>

One entry per static instruction.

block_costs: Vec<u32>

Pre-computed per-basic-block gas cost. Aligned with insts: block_costs[i] is meaningful only when insts[i].is_gas_block_start == true; entries at non- block-start indices are 0. Each meaningful entry is max(simulation_cycles - 3, 1) for the block starting at that instruction, computed by the pipeline simulator in gas_cost::rv_gas_cost_for_block.

block_reserves: Vec<u32>

Pre-computed per-basic-block worst-case category-#3 reserve. Aligned with insts exactly like block_costs: meaningful only at block-start indices, 0 elsewhere. The block-entry gate checks gas ≥ block_costs[i] + block_reserves[i] but charges only block_costs[i] — the reserve is a gate, not a charge (see gas_cost::rv_block_reserve_for_block).

decode_error_at: Option<u32>

If decode hit a reserved/illegal encoding, the byte offset of the first one. None on success.
