Project Scope

Enable/optimize AddressSanitizer function on RISC-V architecture. The major work is to port AddressSanitizer to RISC-V architecture both in GCC and LLVM, both for RV32 and RV64, both from pure software and hardware-software co-design.

...

The tool consists of a compiler instrumentation module which works as an LLVM pass and a run-time library which replaces the malloc function.

• For LLVM:

The instrumentation module is maintained in LLVM backend. (llvm/lib/Transforms/Instrumentation/AddressSanitizer.cpp)

The run-time libraries tailored for AddressSanitizer can be found in compiler-rt/lib/asan and compiler-rt/lib/sanitizer_common.

• For GCC:

The instrumentation module is maintained in GCC backend.
