Abstract

A high level shader language compiler incorporates transforms to optimize shader code for graphics processing hardware. An instruction reordering transform determines instruction encapsulations of dependent instructions that reduce concurrent register usage by the shader. A phase pulling transform re-organizes the shader's instructions into phases that reduce a measure of depth of texture loads. A register assigning transform assigns registers to lower register usage by the shader.
