pub trait KnownOffsetTable: Index<KnownOffset, Output = i32> { }Expand description
A table mapping KnownOffset identifiers to their i32 offset values.
When encoding instructions, Cranelift may not know all of the information
needed to construct an immediate. Specifically, addressing modes that
require knowing the size of the tail arguments or outgoing arguments (see
SyntheticAmode::finalize) will not know these sizes until emission.
This table allows up to do a “late” look up of these values by their
KnownOffset.
Implementations on Foreign Types§
impl KnownOffsetTable for Vec<i32>
impl KnownOffsetTable for [i32; 2]
Provide a convenient implementation for testing.
