[github-actions]

The provided diff consists of numerous small, localized changes across various benchmark files. Here is a summary of the most significant and recurring types of changes:

1. Simplification of Branch Conditions: Multiple instances replace complex branch merge logic (e.g., or of two conditions) with simpler direct use of one condition. For example, in saigRetMin.ll, %brmerge = or i1 %.0.lcssa, %.not is replaced with br i1 %.0.lcssa, indicating that one operand dominates or the other was redundant.

2. Optimization of PHI Nodes and Value Selection: Several functions eliminate unnecessary PHI nodes and conditional selects. In symbolize.ll, redundant phi values and an and operation are removed, simplifying control flow and reducing value tracking complexity.

3. Improved Code Generation for Range/Or Patterns: Functions like cord.ll, io_util.ll, and hermes/CodeBlock.ll now directly compute combined values using or disjoint instead of separate loads and inserts into PHI nodes, reducing instruction count and improving clarity.

4. Loop Exit and Critical Edge Handling: Many changes restructure loop exits by introducing new .loopexit blocks and redirecting branches to them, often merging cleanup paths. This improves control flow structure and enables better optimization (e.g., in casadi/interpolant.ll).

5. Reduction of SROA Artifacts: Across multiple files (box2d, folly, grpc), struct field reconstruction via SROA (Scalar Replacement of Aggregates) is simplified—unnecessary or and insert operations are removed, returning single reconstructed values directly.

These changes reflect optimizations focused on reducing redundancy, simplifying control flow, and eliminating intermediate steps in value computation, likely resulting from improved static analysis or code generation passes.
