Struct AmodeOffsetPlusKnownOffset

pub struct AmodeOffsetPlusKnownOffset {
    pub simm32: AmodeOffset,
    pub offset: Option<KnownOffset>,
}

An AmodeOffset immediate with an optional known offset.

Cranelift does not know certain offsets until emission time. To accommodate Cranelift, this structure stores an optional KnownOffset. The following happens immediately before emission:

• the KnownOffset is looked up, mapping it to an offset value
• the [Simm32] value is added to the offset value

Fields

simm32: AmodeOffset

offset: Option<KnownOffset>

Implementations

impl AmodeOffsetPlusKnownOffset

pub fn value(&self, offsets: &impl KnownOffsetTable) -> i32

Panics

Panics if the sum of the immediate and the known offset value overflows.
