Struct BlockView 

pub struct BlockView<'a> {
    pub ctx: &'a Context<'static>,
    pub block: BlockId,
}

A read-only look at a block, for choosing sites.

Fields

ctx: &'a Context<'static>

block: BlockId

Implementations

impl BlockView<'_>

pub fn address(&self) -> Option<u64>

The block’s guest address, if it starts at one.

pub fn entry(&self) -> Option<Site>

The site at the block’s entry, if the block starts at a guest address.

Anchored on the first instruction that is not an interrupt an earlier hook placed at the entry, so hooks on the same entry fire in registration order and a hook recognises its own anchor when asked again.

pub fn addresses(&self) -> Vec<Site>

Every guest instruction that starts in the block, in order, as a site on the first instruction lifted from it.

One guest instruction’s p-code may branch within itself, so a block with no address of its own can open with the tail of an instruction begun in its predecessor. Those instructions carry the predecessor’s last address; they are a continuation, not a start, and get no site.

pub fn at(&self, address: u64) -> Option<Site>

The instruction addressed by the guest instruction at address, as a site, if the block covers it.

pub fn stores(&self) -> Vec<Site>

Every store to guest memory, in order.

pub fn loads(&self) -> Vec<Site>

Every load from guest memory, in order.

pub fn compares(&self) -> Vec<Site>

Every integer comparison, in order.
