From: Scott Mitchell <[email protected]> This series optimizes RTE_PTR_ADD and RTE_PTR_SUB by using char* pointer arithmetic instead of uintptr_t casts when operating on pointer types. This enables better compiler optimization, particularly for Clang which can now recognize simple pointer patterns and apply vectorization, loop unrolling, and improved assembly.
The implementation uses C11 _Generic to dispatch based on input type, maintaining full API compatibility while enabling ~40-8x performance improvements in checksum operations. The second patch adds a .mailmap entry for consistent git attribution.
