Research direction
Start by locating the decompiler or intermediate-representation logic that handles the shown a3 u< 8 followed by a3 != 0 pattern; the issue names no file, test, or entry point. Use the example and internal binary sparkle giraffe juggling toaster at 1c000a287 as the reference case, and consider the work done when that conditional is simplified without changing the result.
