- Mar 18, 2026 Loop Unrolling, Trip Counts, and the Cost of Code Growth Unrolling by a known factor removes loop overhead and enables scheduling across iterations, but it needs trip-count knowledge, a remainder loop, and a register-pressure check to pay off. compilers
- Feb 5, 2026 Loop-Invariant Code Motion and the Conditions It Needs Hoisting an expression out of a loop requires proving it computes the same value on every iteration, and each of the conditions that license it fails in a way that costs correctness rather than speed. compilers
- Apr 8, 2024 Modulo Scheduling and Software Pipelining How a loop is transformed so that successive iterations overlap in the pipeline, what the initiation interval bounds are, and why prologue and epilogue code appears at the edges. compilers
