🔍 LessVM Codebase Analysis Report

After a thorough examination of the codebase, I've identified several areas for improvement in the LessVM implementation:

• Bugs: The SIMD implementation in vector_add() incorrectly adds a vector to itself, fixed memory size (1024 bytes) restricts complex applications, and many opcodes defined in opcodes.rs lack implementation in core.rs
• Limitations: Data structures have restrictive fixed maximum sizes and the compiler implementation doesn't actually compile code to VM bytecode
• Improvement Opportunities: Dynamic memory allocation, complete opcode implementations, more granular gas costs, bytecode validation, and extended platform compatibility

No changes were implemented as this was a pure analysis task, but I recommend prioritizing the memory management and SIMD implementation fixes.
