Summary: Peeling should not occur during the full unrolling invocation early in the pipeline, but rather later with partial and runtime loop unrolling. The later loop unrolling invocation will also eventually utilize profile summary and branch frequency information, which we would like to use to control peeling. And for ThinLTO we want to delay peeling until the backend (post thin link) phase, just as we do for most types of unrolling. Ensure peeling doesn't occur during the full unrolling invocation by adding a parameter to the shared implementation function, similar to the way partial and runtime loop unrolling are disabled. Performance results for ThinLTO suggest this has a neutral to positive effect on some internal benchmarks.
