Implementations

impl DataValue[src]

    imm: i64,
    ty: Type
) -> Result<DataValue, DataValueCastFailure>[src]

Try to cast an immediate integer (a wrapped i64 on most Cranelift instructions) to the given Cranelift Type.

pub fn ty(&self) -> Type[src]

Return the Cranelift IR Type for this DataValue.

pub fn is_vector(&self) -> bool[src]

Return true if the value is a vector (i.e. DataValue::V128).

pub unsafe fn write_value_to(&self, p: *mut u128)[src]

Write a DataValue to a memory location.

pub unsafe fn read_value_from(p: *const u128, ty: Type) -> Self[src]
