Struct Start 

pub struct Start {
    pub decl: u32,
    pub block: Block,
    pub after: Option<Inst>,
}

Where a declaration starts holding a value, when that is not where the value was computed.

The block and the instruction in front of the assignment, because an assignment that computes nothing is not an instruction and the one in front of it is the nearest thing that is. The block is carried for a start at the top of one, and for the rest it is where the start was made, since a pass can move the instruction to another block. Func::start_place says where it is now.

Fields

decl: u32

The declaration, in whatever numbering the front end gave it.

block: Block

The block the assignment is in.

after: Option<Inst>

The instruction in front of the assignment, or None for one at the top of the block.
