Here is a concise summary of the major changes in this LLVM IR diff:

1. Optimized Pointer Arithmetic via select + getelementptr: Multiple files replace chains of getelementptr instructions (e.g., gep A, i64 X; gep B, i64 Y) with direct offset computation using select to choose between two base offsets, followed by a single getelementptr. This reduces instruction count and improves locality (e.g., giaNf.ll, str_cat_test.ll, vtls.ll, Curl_ssl_conn_config_update).

2. Refined Structure Layout Accesses: Several patches adjust hardcoded struct field offsets (e.g., 52 → 54, 1504 → 1625) used in getelementptr instructions, likely reflecting updated type layouts or ABI changes in the source C++ code (btAxisSweep3.ll, vtls.ll, http_digest.ll).

3. Improved Exception Handling Flow: In MDLMaterialLoader.ll, the invoke instruction’s unwind destination is updated from %28 to %46, correcting control flow after an exception is caught and rethrown.

4. Elimination of Redundant Intermediate GEPs: Many locations remove unnecessary getelementptr steps that were used solely to compute an address before loading/storing. Instead, loads/stores now use the directly computed getelementptr (e.g., clamdtop.ll, cmGeneratorExpressionNode.ll, yyjson.ll). This simplifies the IR and removes dead pointer values.

5. Corrected PHI Node Block References: Several files fix PHI node predecessor block references to match updated control flow (e.g., changing %107 to %108, %61 to %62), ensuring accurate SSA form after other IR transformations (str_cat_test.ll, clamdtop.ll, cmWorkerPool.ll).
