pub struct SinkOperandDefs;Expand description
This transformation sinks constants as close as possible to their uses, one of two ways:
-
If there exists only a single use of the constant, move it before it’s use so that it is in an ideal position for code generation.
-
If there exist multiple uses, materialize a duplicate constant for all but one of the uses, placing them before the use. The last use will receive the original constant.
To make this rewrite even more useful, we take care to place the constant at a position before the using op, such that when generating code, the constant value will be placed on the stack at the appropriate place relative to the other operands of the using op. This makes the operand stack scheduling optimizer’s job easier.
The purpose of this rewrite is to improve the quality of generated code by reducing the live ranges of values that are trivial to materialize on-demand.
