This creates a new tab that shows\nthe shader's source as well as static analysis statistics.\n\nTo see the specific shader bound to a specific stage in the pipeline, view that\nstage in the [**Pipeline** view](/games/agi/refdocs/pipeline-view-pane).\n**Figure 1.** **Shader** pane\n\nSelect shader code\n------------------\n\nYou can select either **SPIR-V** or, if possible, **GLSL**. Note:\n\n- If the SPIR-V code provides the original GLSL code in its OpSource instruction, the **GLSL** tab simply shows the same code. If not, AGI attempts to decompile the SPIR-V into GLSL using SPIRV-Cross.\n- If an error occurs in the decompilation, the option to show GLSL source code isn't available.\n\nStatic analysis\n---------------\n\nAGI provides statistics from a static analysis of the SPIR-V shader. Here are\nthe statistics supported:\n\n| Statistic | Description |\n|----------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| ALU Instructions | Number of instructions in the shader that uses the ALU. |\n| Texture Instructions | Number of texture fetches in the shader. |\n| Branch Instructions | Number of branching instructions in the shader. |\n| Peak Temporary Register Pressure | The highest number of concurrently live temporary registers. A temporary value's lifetime starts at its defition and ends at its last use in the shader. The statistic adds *p* the number of registers each live value uses (for example, a 4D float would be 4 registers). |"]]
