SwitchSpec

Struct SwitchSpec 

Source
pub struct SwitchSpec<'a> {
    pub selector: &'a str,
    pub cases: &'a [u64],
    pub default_addr: u64,
    pub dispatch: &'a str,
    pub table_va: u64,
    pub cmp_ip: u64,
}
Expand description

Structured switch-dispatch spec, passed to ArchCodec::encode_switch_dispatch. Holds everything the x86 MSVC encoder needs; arches that don’t model jump-table dispatch return Unsupported.

Fields§

§selector: &'a str

Register name (e.g. "ecx") holding the case selector.

§cases: &'a [u64]

The case-target addresses, in case-index order.

§default_addr: u64

Target for out-of-range selectors.

§dispatch: &'a str

Dispatch shape identifier — "msvc-jmp-table" today. Implementations match on this and return Unsupported for shapes they don’t recognise.

§table_va: u64

Absolute virtual address where the jump-table data lives.

§cmp_ip: u64

Absolute address of the dispatch’s first instruction.
