[Impeller] malioc diff should label the components in the shortest/longest cycle output and include stack spilling. #120401
Description
I believe these will each correspond to arithmetic, load/store, texture, et cetera components. We should labels these and print which one is the bottleneck. In general, we may wish to change shaders such that we increase the usage of a component which is not a bottleneck in exchange for decreasing the usage of a component that is bottlencked.
For example, I uses the text output which contains these labels:
- Work registers: 4 (100% used at 100% occupancy)
+ Work registers: 3 (75% used at 100% occupancy)
- Uniform registers: 2 (10% used)
+ Uniform registers: 2 (9% used)
Stack spilling: false
