Developed RISC-V Vector (RVV) support for rv64gcv targets in the JoltPhysics repository, focusing on enabling efficient vectorized physics computations on RISC-V hardware. The work involved implementing sizeless RVV vector types as arrays of scalars and introducing a new RISCVVector.h header with helper functions for vector shuffling, modeled after ARMNeon.h patterns. By integrating RVV into core mathematical operations, the developer improved both performance and compatibility for RISC-V architectures. Utilizing C++ and low-level programming techniques, the contribution established reusable vector utilities and aligned with a multi-architecture performance roadmap, laying a foundation for future vectorization efforts across platforms.
