Struct BranchInsts 

pub struct BranchInsts {
    pub prefix: &'static str,
    pub cond: &'static str,
    pub test: &'static str,
    pub if_true: &'static str,
    pub if_false: &'static str,
    pub jump: &'static str,
}

Every instruction a laid out branch is made of.

Fields

prefix: &'static str

What a rule file and the machine IR put in front of this target’s opcodes, such as x64., which says which target a term belongs to and is not part of the opcode.

cond: &'static str

What a lowering rule selects for a conditional branch, which is what the layout replaces.

It reads the condition and does nothing, which is as much of a branch as a rule can say. Naming it here is what lets the layout find one and be sure it has found one, rather than assuming that whatever a two-armed block ends with must be the branch.

test: &'static str

Reads the register the branch is on and sets the condition state from whether it is zero.

if_true: &'static str

Goes to the block’s first successor when the condition held.

if_false: &'static str

Goes to the block’s first successor when the condition did not hold.

jump: &'static str

Goes to the block’s first successor.
