ALU Packing Window

Are there any plans to improve this window?

For example, the window size is not paritcularly large AND the window doesn't seem to "slide".

Example: If you have a kernel that has 100 instructions with 100% data dependency that arer non-vectorized (only use 1/5 VLIW) and then another 100 the same way but with no data dependency across the two 100 instruction sets you get no packing from compiler.

ALU Packing Window

Ryta,
If you can provide test cases of this happening, I can forward it to the shader compiler team for analysis.
