About

Valgrind is a widely-used instrumentation framework that is utilized for the development of dynamic analysis tools, including memcheck, which is particularly helpful in identifying memory management problems.

Project Scope

1. A framework for vector support
2. Several (tens of) RVV instructions support in Valgrind, it can run the following test cases and detect the memory issues (memcheck)
   1. https://github.com/riscv/riscv-v-spec/tree/master/example
